Twentieth Century to 1945

Greater Philadelphia, the “Workshop of the World,” felt the impact of national and international events during two world wars and the Great Depression. Although the region’s rate of industrial growth slowed in the first half of the twentieth century, the demands created by war energized manufacturing, particularly in shipyards on both sides of the Delaware River. The textile industry also boomed during the 1920s before being undercut by the onset of the Depression.

By the 1920s, movements of people and industries signaled a new era. The surge of immigration from eastern and southern Europe that had begun in the late nineteenth century came to an end with the First World War and immigration quotas imposed in 1924. The region did not lack for newcomers, however, as the employment opportunities created during the world wars helped to spur the Great Migration of African Americans from the South. African Americans formed new communities, churches, and cultural institutions in much of West and North Philadelphia, in Camden, and in other cities of the region.

At the same time, there were signs of a suburbanizing trend in business and industry. Notably, Baldwin Locomotive moved its production lines from Philadelphia to Eddystone, Delaware County, in 1929. Knitting and lace plants opened in the suburbs in the 1920s, some relocating from Philadelphia. Department stores, the anchors of central business districts, also began to open suburban branch stores. Although an “arsenal for democracy” for World War II, Greater Philadelphia was coming to the end of its industrial prime.

Topics: Twentieth Century to 1945

Academy of Natural Sciences of Drexel University

A group of six amateur scientists with an interest in natural history gathered at a private residence at High and Second Streets in Philadelphia on January 25, 1812, and founded the Academy of Natural Sciences of Philadelphia for, according to its charter, “the encouragement and cultivation of the Sciences” and “the advancement of useful learning.” ⇒ Read More

Admiral Wilson Boulevard

Admiral Wilson Boulevard, a two-and-a-half-mile section of U.S. Route 30 extending from the Benjamin Franklin Bridge in Camden to the Route 70 overpass in Pennsauken, was the first “auto strip” in the United States. Originally named Bridge Approach Boulevard when it opened in 1926, it was renamed in 1929 to honor Rear Admiral Henry Braid ⇒ Read More

African American Migration

People of African descent have migrated to Philadelphia since the seventeenth century. First arriving in bondage, either directly from Africa or by way of the Caribbean, they soon developed a small but robust community that grew throughout the eighteenth and nineteenth centuries. Although African Americans faced employment discrimination, disfranchisement, and periodic race riots in the ⇒ Read More

Airports

Commercial aviation grew dramatically in the United States in the twentieth century, and a number of airports in the Philadelphia area grew to become regional centers of the industry. There was nothing assured or inevitable about this growth, however. It depended on the efforts of local political leaders, investments by the aviation companies, and state ⇒ Read More

Almshouses (Poorhouses)

From the late seventeenth century to the early twentieth century, almshouses offered food, shelter, clothing, and medical care to the poorest and most vulnerable, often in exchange for hard labor and forfeiture of freedom. Those who entered the Philadelphia region’s almshouses, willingly or unwillingly, rarely accepted this exchange and often protested their treatment or blatantly ⇒ Read More

American Friends Service Committee

The American Friends Service Committee (AFSC), co-recipient of the Nobel Peace Prize and coiner of the phrase “speak truth to power,” was founded in Philadelphia by members of the Religious Society of Friends (Quakers) in Spring 1917, shortly after the United States declared war on Germany on April 6. Over the following century, AFSC embodied ⇒ Read More

American Philosophical Society

Well before the Declaration of Independence, in 1743 Benjamin Franklin (1706-90) and his friend the Quaker botanist John Bartram (1699-1777) established the American Philosophical Society in Philadelphia as a declaration of scientific independence from Great Britain’s scientific domination. The APS developed from a group of local intellectuals keen on expanding human knowledge to serve informally ⇒ Read More

Animal Protection

Moral doubt over the cruel usage of animals has a long history in Philadelphia. Public disapproval of such treatment surfaced by the late eighteenth century, but even with comprehensive laws designed to protect animals, and organizations devoted to enforcing those laws, the region has struggled to extend adequate protection to its nonhuman animals. Benjamin Franklin ⇒ Read More

Arboretums

The Philadelphia area is a recognized “hearth” of early American arboretums. Starting almost exclusively within a tight-knit community of Quaker botanists with a reverence for nature, early Philadelphia arboretums left a legacy of emphasis on native plants. Over time, the region’s arboretums also encompassed English naturalistic designs showcasing North American species and increasingly global perspectives, ⇒ Read More

Armories

Armories served as military training and recruiting sites, arms depots, headquarters, and social clubs for the nation’s citizen-soldiers. Early armories in Philadelphia were simply rented spaces in commercial buildings. After the Civil War, permanent structures for the exclusive use of the Pennsylvania National Guard supplanted these ad hoc armories as business interests responded to labor ⇒ Read More

Armstrong Association of Philadelphia

The Armstrong Association of Philadelphia was a social-service organization established early in the twentieth century to assess and address the needs of the African American community. Through its efforts to improve education, housing, and health, the organization addressed social and economic issues facing African Americans. Founded in 1908, the association formed as a branch of ⇒ Read More

Arsenals

For much of the nation’s history Philadelphia held a preeminent position as the provider of logistical support to the U.S. Army, and federal arsenals played a considerable role in the economic life of the city. The Schuylkill Arsenal and Frankford Arsenal were, respectively, the largest manufacturers of uniforms and small-arms ammunition in the country, often ⇒ Read More

Art Colonies

Outside the urban core of Philadelphia, the picturesque rural landscape proved a significant draw to many artists in search of the purportedly simple, wholesome, and moral quality of countryside living. Whether planned and intentional or more organic and serendipitous, colonies like those in New Hope, Chadds Ford, and Rose Valley in Pennsylvania, and Arden and ⇒ Read More

Art Deco

Like other major American cities in the 1920s and 1930s, Philadelphia was an epicenter for the exuberant strain of architecture and design activity that came to be known as Art Deco. Fueled by the area’s economic importance and increasingly urban character after the First World War, designers, corporations, and manufacturers all engaged in a broad ⇒ Read More

Art of Cecilia Beaux

The elegant portraits of Cecilia Beaux (1855-1942) found unanimous critical acclaim in Philadelphia, Paris, and New York. Her modern style of painting combined the best of academic training, European sophistication, and experimentation. Beaux successfully negotiated the gender separatism of the late nineteenth century while she gained international renown, allowing her to become the first full-time ⇒ Read More

Art of Dox Thrash

Dox Thrash (1893-1965) was an accomplished draftsman, printmaker, watercolorist, and painter, whose art reflected his experiences as an African American in Philadelphia. He became well known in the 1940s after developing the Carborundum printmaking technique at the Philadelphia Fine Print Workshop (311 Broad Street) of the Works Progress Administration’s Federal Art Project. By rubbing coarse ⇒ Read More

Art of Thomas Eakins

The art of Thomas Eakins (1844-1916) is more deeply entwined with the city of Philadelphia than that of any other artist of the nineteenth century. Born in North Philadelphia in 1844, Eakins spent nearly his entire life in the city. He consistently took local residents as his subjects, portraying friends, family, and individuals he admired engaged ⇒ Read More

Arts and Crafts Movement

The Arts and Crafts movement in Greater Philadelphia grew against the backdrop of the area’s increasingly industrial character in the late nineteenth and early twentieth centuries. The 1876 Centennial Exhibition brought attention to Philadelphia’s prominence as a manufacturing center and fostered a renewed sense of pride in the city’s connections to national history, but it ⇒ Read More

Arts of Wharton Esherick

The unconventional artistic trajectory and prolific work of prominent Philadelphia-area artist and craftsman Wharton Esherick (1877–1970) have been claimed for and by multiple movements in the history of twentieth-century American art, from early-twentieth-century Arts and Crafts to postwar studio craft. Working across a wide variety of media, including printmaking, sculpture, furniture, and theatrical design, Esherick ⇒ Read More

Astronomy

Philadelphians embraced the study of celestial phenomena and bodies, such as stars, planets, and comets, from an early date. As early as 1769, the American Philosophical Society’s involvement in tracking that year’s transit of Venus gained transatlantic scientific attention. Astronomy remained a popular scientific pursuit throughout the region’s history; the Franklin Institute and Rittenhouse Astronomical ⇒ Read More

Athenæum of Philadelphia

The Athenæum of Philadelphia, a non-profit, member-supported library, was founded in 1814 “to disseminate useful knowledge.” Threatened for its very existence with the advent of the city’s free library in 1894, the organization subsequently recovered and ultimately thrived as it reinvented itself as a special- collections library with related public exhibitions, lectures, and publications. Unlike ⇒ Read More

Atlantic City

Before Disneyland, Atlantic City was the first great middle-class resort in the nation, especially the Philadelphia region. From its founding in the 1850s through the early decades of the twenty-first century, Atlantic City succeeded and failed based on its ability to make itself in the image of the American middle class. As the cultural tastes ⇒ Read More

Automats

Beloved by generations of diners and immortalized in art, song, cinema, and poetic verse, Automats, also known as “automatics” or “waiterless restaurants,” were popular manifestations of an early-twentieth century modernizing impulse. Influenced by studies of scientific management by Frederick W. Taylor and the widespread use of the assembly line, the Automat removed the process of ⇒ Read More

Automobile Racing

Motorsports developed into a popular leisure activity in the Philadelphia area during the twentieth century. Originally an activity enjoyed by wealthy car owners, the advent of the Model T Ford allowed local technophiles to build their own race cars and compete in regional races. By mid-century, drivers raced at fairground horse tracks and purpose-built speedways ⇒ Read More

Automobiles

Since appearing in the 1890s, automobiles have in many ways shaped Greater Philadelphia’s history and geography. Initially a luxury item and later available on a massive scale, cars, while enhancing mobility, required billions of dollars in infrastructure, reordered the landscape of every town and city, and made indelible marks on the region’s architecture, culture, and ⇒ Read More

Automotive Manufacturing

Once a mainstay of Greater Philadelphia’s industrial might and a reflection of the socioeconomic transformations of the twentieth and early twenty-first centuries, the manufacturing of automobiles and related components provided mobility for millions, jobs for many thousands, and lifeblood for towns and cities. First appearing in the 1900s, flourishing during the interwar and postwar periods, ⇒ Read More

Bakeries and Bakers

Baking, one of the earliest businesses in Philadelphia, did not become a major part of the local economy until the late nineteenth century. It remained a viable industry throughout the region’s history, however, ranging from small neighborhood bakeries to large baking companies with national product distribution. Philadelphia supported several commercial bakers from the beginning. A ⇒ Read More

Ballet

Philadelphia has a rich ballet history that spans centuries. Although initially not hospitable to dance, the city developed into an attractive destination for international ballet dancers and teachers and eventually produced the first genuine ballerinas born in the United States, the first thoroughly American ballet troupe, and one of the most prominent of the regional ⇒ Read More

Bank of North America

Chartered May 26, 1781, by the Continental Congress under the Articles of Confederation, this enterprise was the first national and truly commercial bank in the United States. Officially titled The President, Directors, and Company of the Bank of North America (BNA) until 1825, the bank was the first created by the national government to do ⇒ Read More

Banking

Greater Philadelphia’s banking roots go deeper than those of any region in the country. Philadelphia was the home of the first commercial bank (1782), the first national bank (1791), the first savings bank (1816), and the first savings and loan association (1831). Until the mid-1980s, celebrated local institutions such as First Pennsylvania, Girard, and Provident ⇒ Read More

Barbershops and Barbers

Throughout much of its modern American history, barbering has been derided as “servile” work, unfit for native-born, white citizens. As such, the profession has been dominated by marginalized groups. In the Philadelphia region, African Americans owned and operated the majority of barber shops during the eighteenth and early nineteenth centuries. Since then, waves of immigrant ⇒ Read More

Barnes Foundation

Businessman, chemist, educator, and art collector Dr. Albert C. Barnes (1872-1951) established the Barnes Foundation in 1922 as a center for art education organized around his growing collection of paintings, sculpture, and furniture. The institution earned international renown, less for its pedagogy than for its art collection, which by mid-century was world-class. Initially based in ⇒ Read More

Bartram’s Garden

Located on the west bank of the Schuylkill River, Bartram’s Garden, considered the oldest surviving botanic garden in North America, has served as a monument to the storied history of Philadelphia’s botanical endeavors and to the genius of John Bartram (1699–1777) and his descendants. Established as a family farm and garden by John Bartram in ⇒ Read More

Baseball: Negro Leagues

More than any other city, Philadelphia epitomized the significance of Negro League baseball in urban communities. For a remarkable eight decades, local fans consistently supported a series of black ball clubs whose successes generated racial pride and represented a triumph of African American institution-building. In Philadelphia, the first all-black baseball teams surfaced in the 1860s. ⇒ Read More

Baseball: Professional

From the time the game was created to its organization into a professional league, and from the first National League game ever played to some of the earliest World Series, the city of Philadelphia has played a prominent role in professional baseball history. Variations of the game of baseball became popular some three decades prior ⇒ Read More

Benjamin Franklin Parkway

Created in the first decades of the twentieth century, the Benjamin Franklin Parkway connected the heart of Philadelphia’s downtown to its premier park and over time became a district of cultural institutions and a commons for civic celebrations. The broad boulevard and its monumental structures reflected the European-inspired, nationwide City Beautiful Movement embraced by the ⇒ Read More

Bicycles

Since the nineteenth century, bicycles have enamored the American public as tools of transportation, sport, exercise, and joy. The Philadelphia area has been intimately connected with the development of the two-wheeled, human-powered machine from its early appearance in North America to the adoption of bike-share programs and the blazing of interstate trail networks in the ⇒ Read More

Billiards (Pool)

Billiards, the traditional name for games played on a table with balls and a cue stick, of which there are a number of variations, has been played in Philadelphia since at least the late 1700s. Played on a table with six pockets and either nine or fifteen balls, billiards is referred to as pocket billiards ⇒ Read More

Bloody Fifth Ward

Philadelphia’s Fifth Ward, south of Chestnut Street near the Delaware River, became infamous in the late nineteenth century for election-day riots among the Irish, blacks, and the police, with ward boss William “Bull” McMullen (1824-1901) at the center of the violence. By the early twentieth century, the area had become known as the “Bloody Fifth,” ⇒ Read More

Blue Route

Famous for the many protracted conflicts that delayed its full construction for decades, Pennsylvania’s Mid-County Expressway, also referred to as the Veterans Memorial Highway and, more commonly, the “Blue Route,” is the southernmost section of Interstate 476. The expressway stretches through southern Montgomery and Delaware Counties, linking the Pennsylvania Turnpike interchange at Plymouth Meeting with ⇒ Read More

Board of Health (Philadelphia)

Philadelphia suffered numerous outbreaks of epidemic disease throughout the seventeenth and eighteenth centuries, but it was not until 1794, in the wake of the disastrous 1793 yellow fever outbreak, that a group of concerned citizens founded the Board of Health, independent of the city’s control. In the nineteenth century, the city supported the board with ⇒ Read More

Boarding and Lodging Houses

Distinguished by its ubiquitous row houses and high rates of home ownership, Philadelphia has been long been known as a “city of homes.” But for much of its history, it also has been a city of boardinghouses. “Boarding” and “lodging” houses did not enter the local lexicon until the late eighteenth century, but the practice ⇒ Read More

Boathouse Row

Philadelphia’s Boathouse Row is a National Historic Landmark that reflects the city’s fusion of sport, culture, and history. The boathouses, built in the second half of the nineteenth-century, line the eastern bank of the Schuylkill River just north of the Fairmount Waterworks. Lit at night with thousands of glowing bulbs, they form a welcoming beacon ⇒ Read More

Book Publishing and Publishers

Between 1750 and 1800, Philadelphia became the center for book printing and publishing in the United States, surpassing New York and Boston. Although Philadelphia lost that primacy in the nineteenth century, firms specializing in medical and religious publishing continued to do well. By the mid to late twentieth century, however, as the publishing industry consolidated, ⇒ Read More

Bookselling

Bookstores have long been an important part of the economic and cultural fabric of Philadelphia. As early as the eighteenth century, booksellers set up shop in the city, eager to serve a highly-educated population hungry for information. In the nineteenth and early twentieth centuries, the number of bookstores continued to rise. These stores sold a ⇒ Read More

Bootlegging

Bootleg liquor, produced illegally during Prohibition (1920-33), flowed into the Philadelphia region from a variety of sources, including overseas shipments, small home stills, large stills in urban factories and country barns, beer breweries, and manufacturers of industrial alcohol. Philadelphia’s location at the confluence of the Delaware and Schuylkill Rivers, just inland from the Atlantic Ocean, ⇒ Read More

Botany

Beginning in the eighteenth century with the botanical enthusiasts who explored the world around them as part of a larger interest in natural history, botany became an integral part of the Philadelphia region’s national and international reputation. It brought scholars and enthusiasts from across the globe to study and explore Philadelphia’s collections and gardens, influenced ⇒ Read More

Boxing and Boxers

For over one hundred years, Philadelphia neighborhoods, for better and worse, played a significant role in molding fighters. Over two dozen world boxing champions throughout various weight classes called Philadelphia home. Nearby communities such as Camden, New Jersey, and Easton, Pennsylvania, also produced world champions. Over time, Philadelphia-area boxing was supported by a wide network ⇒ Read More

Brickmaking and Brickmakers

The city of Philadelphia was built with bricks, giving it an appearance many neighborhoods retained into the twenty-first century. An abundance of local clay allowed brickmaking to flourish and bricks to become the one of the most important building materials in the region. Because it could be accomplished with just a few rudimentary tools, brickmaking ⇒ Read More

Bridgeton, New Jersey

Bridgeton, the governmental seat of Cumberland County, originated in the late seventeenth century as a fording place at the upper tidal reach of the Cohansey River, a tributary of the Delaware Bay. Located seven direct miles from the bay (though twenty by meandering river), and about forty miles south of Philadelphia, Bridgeton drew on water ⇒ Read More

Broad Street

“No other street in America quite compares with Broad Street,” wrote E. Digby Baltzell, author of Puritan Boston and Quaker Philadelphia, of the varied architecture north and south of City Hall. Philadelphia’s Broad Street goes past stores, churches, synagogues, museums, funeral parlors, fast food places, gas stations, apartment houses, and rows and rows of row ⇒ Read More

Bucks County, Pennsylvania

Bucks County, one of three counties established in 1682 by William Penn (1644-1718), originally stretched northward along the Delaware River all the way to the Delaware Water Gap and westward past Allentown. Even after shrinking dramatically when Northampton and Lehigh Counties were carved from its territory in 1752, the county still encompassed multiple regions that ⇒ Read More

Burlesque

In the late nineteenth and early twentieth centuries, Philadelphia became one of the central nodes of American burlesque, a genre with origins in the ribald Victorian “travesties”—theatrical parodies of well-known operas that relied upon risqué and absurd humor. Distinct from its English counterpart, American burlesque incorporated elements of minstrelsy and, especially by the end of ⇒ Read More

Buses

Beginning in the 1920s, the Philadelphia region’s independent transit companies added motorized buses (autobuses) to their networks. Superior in comfort to the horse-drawn omnibuses of the nineteenth century and with more range and versatility than electric trolleys, autobuses offered passengers easier means to traverse the metropolitan area. Prior to the internal combustion engine, mass transit ⇒ Read More

Byberry (Philadelphia State Hospital)

From the arrival of its first patients in 1911 to 1990, when the Commonwealth formally closed it down, the Philadelphia State Hospital, popularly known as Byberry, was the home for thousands of mental patients. In its early decades Byberry was controlled by the city, and from 1938 onward it was one of the several hundred ⇒ Read More

Camden, New Jersey

Incorporated in 1828 and named county seat of the newly formed Camden County when it separated from Gloucester County in 1844, Camden City long served as the heart of the South Jersey region directly across the Delaware River from Philadelphia. Besieged in the second half of the twentieth century by losses of population and economic ⇒ Read More

Campbell Soup Company

Anyone crossing the Benjamin Franklin Bridge from Philadelphia to Camden during most of the twentieth century saw one of the best-known icons of American consumerism, the giant Campbell-Soup-can water towers looming over the company’s flagship cannery. Campbell Soup may have been “America’s Favorite Food,” as the title of the company-sponsored history claims, but it was ⇒ Read More

Carpet Weaving and Rug Making

In its early twentieth-century heyday, Philadelphia’s carpet and rug industry represented this nation’s greatest concentration of factories making household and commercial floor coverings. The Public Ledger boasted that “two wards, in the northern section of the city, produce more carpets than the whole of Great Britain and Ireland.” Indeed, as early as 1882, those Kensington ⇒ Read More

Cartoons and Cartoonists

American cartooning began in Philadelphia. Benjamin Franklin (1706–90), who introduced cartoons to North America, used images to galvanize viewers to action on the issues of their day. As the political, economic, and cultural capital of the early United States, Philadelphia became a center for producing political cartoons and humorous caricatures. Although New York eventually supplanted ⇒ Read More

Cathedral Basilica of Saints Peter and Paul

Established in 1846, the Cathedral Basilica of Saints Peter and Paul at Eighteenth and Race Streets became the principal church and center of Catholic life for the clergy and faithful of the Philadelphia archdiocese. During a turbulent era of immigration and anti-Catholic nativism, Bishop Francis Patrick Kenrick (1796-1863) desired a “common church of the whole ⇒ Read More

Cemeteries

Cemeteries have been integral features of the Philadelphia-area landscape since the earliest European settlements of the mid-1600s. Over the centuries, and in tandem with developments such as epidemics, immigration, industrialization, war, and suburbanization, the region’s cemeteries matured from small, private grave sites, potter’s fields, and church burial yards to rural cemeteries, national cemeteries, and memorial ⇒ Read More

Center City

Forming a core of civic, commercial, and residential life since Philadelphia’s seventeenth-century founding, Center City has been a continually evolving experiment in urban living and management. The roughly rectangular area of about 2.3 square miles between the Delaware and Schuylkill Rivers, from Vine Street to South Street, occupies the territory of the original 1682 city ⇒ Read More

Cheesesteaks

A cheesesteak is a sandwich unlike any John Montagu, the fourth Earl of Sandwich (1718-1792), might have encountered. Thin bits of frizzled beef served on a locally-made Italian roll, usually topped with fried onions and Cheez Whiz drawn from the can with a paint stirrer, the Philly cheesesteak also is distinguished, in part, by its ⇒ Read More

Chemical Industry

Since the eighteenth century, chemical or chemical processing industries have been an important part of the economy of Philadelphia and the Delaware Valley region and have reflected larger trends in the industry. The earliest chemical companies manufactured products such as sulfuric acid and white lead pigments for local consumption, while other manufacturers, such as tanners, ⇒ Read More

Chemistry

Philadelphians used chemistry to enhance manufacturing, household practice, and artisan trades, mixing scholarly with practical aims from the outset. Furthermore, chemistry’s relationship to other scientific disciplines, including botany, geology, and medicine, made Philadelphians particularly keen to promote and diffuse chemical knowledge. Encouraged by widespread interest in chemistry between the eighteenth and twenty-first centuries, a number ⇒ Read More

Chester, Pennsylvania

Located 30 miles down the Delaware River from Philadelphia, the small but once industrially mighty city of Chester emerged in the latter part of the twentieth century as but a shadow of its former prominence in the county and the region. The municipality’s fortunes shifted many times over the 334 years of its existence, evolving ⇒ Read More

Children’s Aid Society of Pennsylvania

The Children’s Aid Society of Pennsylvania was founded in 1882 by a group of predominantly women volunteers to address social issues plaguing the city of Philadelphia, such as drunkenness, child homelessness, and rampant crime. Child welfare advocate Helen W. Hinckley led the charge, assisted by Cornelia Hancock (1840–1928), who had volunteered as a nurse in ⇒ Read More

Chinatown

Settled by Chinese migrants in the 1870s, Philadelphia’s Chinatown grew over the course of the twentieth century from a small ethnic enclave on the outskirts of Skid Row to a vibrant family community in the heart of Center City. Threatened by urban renewal in the 1960s and 1970s, Chinatown residents marshaled the redevelopment process to ⇒ Read More

City Beautiful Movement

Grounded in landscape and European architecture and shaped by the politics of the Progressive Era, the City Beautiful Movement emerged in reaction to the physical decay and social congestion that burdened America’s industrial centers at the turn of the twentieth century. Considered the “mother” of urban planning, its promoters and practitioners sought to reorder the ⇒ Read More

City Hall (Philadelphia)

Constructed over a thirty-year period at a cost approaching $25 million, Philadelphia City Hall stands as a monument both to the city’s grand ambitions and to the extravagance of its political culture. Controversial from the outset–for its location, its architecture, and the patronage it commanded on behalf of its construction–the structure nonetheless came to be ⇒ Read More

Civil Defense

Because of Greater Philadelphia’s position as a political, cultural, and economic hub, the region’s residents have often found their daily lives deeply affected by times of national crisis. Civil defense, generally defined as local voluntary programs designed to protect civilian life and property during times of conflict, has taken many forms: militia, home defense, civilian defense, ⇒ Read More

Civil Rights (African American)

Black Philadelphians have fought for civil rights since the nineteenth century and even before. Early demands focused on the abolition of slavery and desegregation of public accommodations. The movement gained greater power as the nineteenth century gave way to the twentieth and the World War I-era Great Migration brought tens of thousands of African Americans ⇒ Read More

Classical Music

Classical music stands apart from vernacular (or “folk” music) and from “popular” music (in the form of simplified commercial entertainment) in its complexity of structure and high level of performance requirements. Philadelphia established a major position in American classical composition and performance in the early nineteenth century, and maintained that position through its premier professional ⇒ Read More

Clocks and Clockmakers

Clockmaking in colonial and early republican Philadelphia and its environs was considered an intellectual profession requiring great artisanal skill and scientific knowledge. Among rural communities surrounding the city, the mathematical precision and mechanical intricacy of the profession put it at a superior rank to the crafts of blacksmithing and carpentry. Clockmakers like David Rittenhouse (1732-96) ⇒ Read More

Coffeehouses

Philadelphia’s first coffeehouse opened in 1703, and by mid-century half a dozen operated within the city limits. Their purpose, however, changed in important ways as the eighteenth century progressed. Early coffeehouses primarily served the needs of traders and mariners, acting as crucial centers of commerce. In the decades following the American Revolution, however, some coffeehouse ⇒ Read More

College of Physicians of Philadelphia

One of the oldest professional medical societies in the United States, the College of Physicians of Philadelphia was founded in 1787 “to advance the science of medicine and to thereby lessen human misery.” At the time, Philadelphia, home to the first general hospital and medical college, was the center of American medicine. The College of ⇒ Read More

Columbus Day

Observed on the second Monday in October, Columbus Day in the Philadelphia region gained prominence as Italian immigrant communities grew in the late nineteenth and early twentieth century. By commemorating the 1492 arrival of Christopher Columbus (1451-1506) in the New World, Italian-Americans embraced the navigator as their countryman, celebrated Italian culture, and called attention to ⇒ Read More

Commercial Museum

Opened to the public in 1897, the Commercial Museum was the foremost source of international trade knowledge for American manufacturers at the turn of the twentieth century. Located on the western bank of the Schuylkill River in Philadelphia, the museum served as a reference library for merchants, facilitated connections between American export traders and foreign ⇒ Read More

Commuter Trains

Commuter trains have helped to shape and define Philadelphia and its region since their introduction in 1832. The trains influenced suburban development and shaped Center City. For most of this period, the trains charged higher fares than other forms of public transit and remained a largely middle-class means of transport. Commuter trains connected middle-class homes ⇒ Read More

Constitution Commemorations

As a cause for commemoration, the signing of the U.S. Constitution historically has struggled to compete with the Declaration of Independence for national recognition and ardor. In contrast to the dramatic act of independence, the framing of the national government is a more sober and complex narrative not easily celebrated with barbecues and fireworks. In ⇒ Read More

Contractor Bosses (1880s to 1930s)

As Philadelphia expanded physically after its 1854 consolidation of city and county, building contractors wielded a greater degree of political power as they paid politicians and civil servants handsomely for the rights to construct the city’s infrastructure. The late nineteenth century saw the emergence of the “contractor boss”—a construction magnate who wielded political power directly ⇒ Read More

Convents

Convents—communities of women devoted to religious life—in the Greater Philadelphia area played a significant role in the education of youth and in social services for communities from the nineteenth century into the twenty-first century. Although some regional Catholic convents moved or closed during this time, the Philadelphia area remained strong in Catholic identity because of ⇒ Read More

Corrupt and Contented

In July 1903, at the height of the period of reform we have come to call the Progressive Era, crusading journalist Lincoln Steffens published the fifth in a series of articles exposing municipal corruption in the United States. His subject was Philadelphia, and to his mind it was worse than any other place he had ⇒ Read More

Country Clubs

Country clubs originated in the 1890s as elite, family-oriented havens usually emphasizing golf, but they have never been just about golf or even sports. Clubs fostered sportsmanship, appropriate deportment, and social development while also providing opportunities for exercise. A “golden age” of country clubs lasted until the Great Depression of the 1930s, and the number ⇒ Read More

Cricket

The rise, fall, and rebirth of the sport of cricket in the Philadelphia region reflected political, social, and economic change. Cricket once flourished in the city, which produced some legendary players known throughout the cricketing world. The rise of other leisure activities supplanted the game, however, until a moderate resurgence in the late twentieth and ⇒ Read More

Crime

Crime is inextricably linked to Philadelphia’s shifting economic fortunes. Its history reflects the region’s status as a port and point of entry for goods, immigrants, and migrants, where concentrations of both wealth and poverty developed in a center of American commerce and industry. As a type of economic activity, forms of crime changed dramatically as ⇒ Read More

Cycling (Sport)

The Philadelphia area’s connections to the sport of cycling have spanned nearly 200 years, reflecting its rise, decline, and resurgence in the United States. The region’s history of road, track, and all-terrain races began before the invention of the modern “bicycle” and continued into the twenty-first century with new variations of the sport and the ⇒ Read More

Dancing Assembly

Established in the winter of 1748-49, the Dancing Assembly of Philadelphia— also known as “The Assembly” or “The Assemblies”— originated as an occasion for elite men and women to gather for social dancing in carefully matched pairs. Modeled after the English “assembly,” a type of formal social gathering most famously held in Bath and London, ⇒ Read More

Deafness and the Deaf

Documentation of the lives of deaf individuals in the Philadelphia region, and elsewhere, is limited. Historic accounts depict desperate individuals roaming the streets or begging. Prior to the advent of public schools for the deaf, only elite deaf individuals received private tutoring. In the early nineteenth century, Philadelphia philanthropists, religious figures, educators, merchants, and policymakers ⇒ Read More

Deindustrialization

The Philadelphia region’s long-held reputation as the “workshop of the world,” though richly deserved, did not prevent it from suffering the same loss of manufacturing firms and jobs that devastated the economies of other manufacturing centers. Local products ranged widely, from locomotives and ships to silk hosiery, wool carpets, machine tools, hand tools, lighting fixtures, ⇒ Read More

Delaware Avenue (Columbus Boulevard)

Delaware Avenue, the north-south thoroughfare closest to the Delaware River in Philadelphia, owes its existence to the richest man in America, who wanted a grand avenue along the central waterfront. The street, including a portion renamed Columbus Boulevard in the 1990s, played a significant role in the development of Philadelphia’s maritime activity, particularly food distribution ⇒ Read More

Delaware Bay

The Delaware Bay does not often get the historical acknowledgement received by its estuarine neighbor, the Delaware River, but it exerted equal weight in shaping the Philadelphia region’s cultural and economic development. Over seven hundred square miles in size and bordered by New Jersey and Delaware, the Delaware Bay is one of America’s premier maritime ⇒ Read More

Delaware County, Pennsylvania

Carved out of Chester County in 1789 (with the remainder of that county lying to its southwest), Delaware County long served as a distinct but close neighbor to the City of Philadelphia.

Dentistry and Dentists

As dentistry slowly emerged as a profession in the eighteenth and nineteenth centuries, innovative dentists in Philadelphia helped to shape dental care, procedures, and tools.

Department Stores

As department stores became central to retailing in American cities in the late nineteenth and early twentieth centuries, Philadelphia played a major role.

Dogfighting

The cruel practice of dogfighting has thrived in the shadows of the Philadelphia region for more than 150 years.

The process of training and culling weak dogs as well as the fights themselves have ⇒ Read More

Dogs

For as long as people have inhabited Philadelphia and the surrounding area, dogs probably have been present, too. As the first domesticated animal, dogs possess a long, complicated past with humans, likely dating back between fifteen thousand and thirty thousand years.

Dutch (The) and The Netherlands

From seventeenth-century Dutch settlements in the Delaware Valley to twenty-first century business connections, the greater Philadelphia area has had longstanding and meaningful ties with the Netherlands.

The ⇒ Read More

Eastern State Penitentiary

Eastern State Penitentiary, considered by many to be the world’s first full-scale penitentiary, opened in Philadelphia in 1829 and closed in 1971.

Abandoned as a prison in the ⇒ Read More

Education and Opportunity

In the twentieth century, many urban school districts, which had been among the finest in the nation, became some of the most challenged. The Greater Philadelphia region reflected this trend. In 1900 the region’s school systems consisted of largely uncoordinated public, parochial, and private schools. Between 1900 and 1965 politicians, educational administrators, and civic leaders ⇒ Read More

Educational Reform

Since the early nineteenth century, several reform efforts have aimed to improve Philadelphia-area public schools.

Eugenics

In 1883 Francis Galton (1822–1911), an English statistician and sociologist, invented a term for his decades-long genealogical investigations into “fit” and “unfit” families: eugenics, the scientific study of being well-born. While Galton tended to focus on the fit, in the United States, enthusiasts for eugenics more often focused on those deemed biologically unfit. Elwyn, Pennsylvania, ⇒ Read More

Fabric Row

A textile and garment district emerged during the late nineteenth and early twentieth centuries on South Fourth Street, between Catharine and Bainbridge Streets in South Philadelphia, as immigrants transformed the neighborhood into a Jewish Quarter.

Fairmount Park Houses

From the mid-eighteenth century, prominent Philadelphians looking for a rural, healthy, scenic environment built small mansions, or villas, along the Schuylkill River, one of two major waterways that define Philadelphia’s geography. In the early nineteenth century, the city began to acquire properties along the Schuylkill, including these villa houses. These purchases culminated in the 1855 ⇒ Read More

Fairmount Water Works

For more than two centuries, Philadelphia’s Fairmount Water Works provided two vitally important, but different, services to the city. The first began when Philadelphia’s municipal water system—the first of its kind anywhere in the modern world—was moved to Fairmount and enlarged. Thanks to its charming design and placement beside the bucolic Schuylkill River, its second ⇒ Read More

Fashion

Fashion played an important role in Philadelphia’s development as a center for retail and manufacturing.

Ferries

Long before bridges, trestles, and elevated expressways, the people and products of Greater Philadelphia required a network of ferries to traverse the region’s numerous waterways. Once ubiquitous on the area’s rivers, ferries were economic necessities that were phased out over time as industry changed and transportation improved. Until the advent of steam and internal combustion ⇒ Read More

Films (Feature)

Philadelphia’s association with movie-making dates back to the beginning of the film industry, when the city’s Lubin Manufacturing Company created and distributed many of the first generation of silent films.

Food Processing

The food industry has always held a special place in Philadelphia and its surrounding region, though it never became a center of a massive industry like meatpacking in Chicago.

Football: Professional

From the 1950s onward, pro football’s Eagles ruled the sports roost in Philadelphia, having built a dedicated fan base that filled the stadium each week and careened emotionally from each gridiron success and failure.

Funerals and Burial Practices

In the Philadelphia region, burial and funeral rituals have served to honor the dead and comfort the living.

Furnituremaking

From the founding of Philadelphia in 1682 until the late 1800s, a vibrant community of cabinetmakers plied their skills alongside specialists in carving, chair making, and turning.

These tradesmen were as diverse as the city itself, and their complex webs of language, ethnicity, religious ⇒ Read More

Gardens (Public)

More than three centuries of private and public efforts have given the Philadelphia area the highest concentration of public gardens in the United States.

From these beginnings, public gardens became ⇒ Read More

Garment Work and Workers

Garment work was once one of Philadelphia’s largest industries. Clothing and textiles (a category including hosiery, a Philadelphia specialty) employed more than 40 percent of the city’s paid workforce by 1880.

Gas Stations

The widespread adoption of the passenger automobile during the twentieth century altered the physical landscape of Greater Philadelphia and the United States.

Heating (Home)

The Delaware Valley’s frosty winters have always required residents to heat their homes for months at a time.

Higher Education: Private (Religious)

With the exception of Greater Boston, the Philadelphia region has more independent colleges and universities than any other metropolitan area of the United States.

Historic Preservation

Through more than three centuries of building and rebuilding settlements, towns, and cities, the region centered on Philadelphia and spanning southeastern Pennsylvania, South Jersey, and northern Delaware became a living museum of American architectural history. The fate of structures ranging from log cabins and colonial mansions to courthouses, warehouses, and the famed Independence Hall often ⇒ Read More

Historical Societies

Over the nineteenth and twentieth centuries, Americans started establishing historical societies to collect and preserve historical materials.

Hog Island

Hog Island, at the confluence of the Delaware and Schuylkill Rivers, exemplifies many broad trends in the environmental history of the region.

No longer productive in the early twentieth century, the island ⇒ Read More

Home Remedies

Although Philadelphia has been a premier city for medical innovation since the mid-eighteenth century, the diverse peoples of the region also have used home remedies to heal themselves.

Medical recipes often ⇒ Read More

Horses

Horses played a critical role in Philadelphia’s growth and development as an industrial city, but over time their role as prime movers gradually diminished, and after the mid-twentieth century their role was primarily recreational. Although horses have become associated with the countryside or the American West, American cities had large, concentrated populations of horses well ⇒ Read More

Horticulture

The history of horticulture in Philadelphia and the Delaware Valley has been primarily a story of exploration, beautification, and preservation.

Hotels and Motels

As one of the busiest and most influential port cities in colonial and later independent America, Philadelphia became an early leader in hotel development and continued to elevate industry standards throughout the nineteenth and twentieth centuries.

Hurricanes and Tropical Storms

The Greater Philadelphia area’s position near the Atlantic Ocean has made it vulnerable to hurricanes and tropical storms, especially along the Delaware and New Jersey shores, and to flooding from storm surges along the Delaware River. The majority of storms to hit the region have been tropical storms, because hurricanes have tended to weaken over ⇒ Read More

Ice Hockey (Professional)

In February 1966, the National Hockey League decided that the future was now.

Immigration (1870-1930)

During the national explosion of immigration that took place between 1870 and the 1920s, the Philadelphia region became more diverse and cosmopolitan as it was energized by immigrants who indelibly changed the character of the places where they settled.

Immigration (1930-Present)

For most of the decades since the United States’ immigration restriction acts of the 1920s, Philadelphia was not a major destination for immigrants, but at the end of the twentieth century the region re-emerged as a significant gateway.

Industrial Neighborhoods

The growth and decline of industry in the Philadelphia region in the nineteenth and twentieth centuries also shaped the character of many of its neighborhoods.

These row house blocks ⇒ Read More

Industrial Workers of the World

In the early 1900s thousands in greater Philadelphia belonged to the Industrial Workers of the World (IWW)—a militant, leftist labor union.

Indeed, there might not have been a more egalitarian ⇒ Read More

Infectious Diseases and Epidemics

Despite Philadelphia’s prominence, throughout its history, as a center for medical education and care, the region has experienced numerous epidemics of infectious disease.

Inner Suburbs

Presenting a varied and complicated patchwork of both thriving and distressed communities, Philadelphia’s inner suburbs developed during different eras to serve different purposes and populations.

During the eighteenth ⇒ Read More

Insurance

Insurance is sometimes called an “invisible” element of commerce, but in Philadelphia, it has never been far from view.

Irish (The) and Ireland

Contacts between the Philadelphia region and Ireland began in the late seventeenth century, shortly after the creation of Penn’s colony.

Jazz

Jazz began to emerge as a distinct musical style around the turn of the twentieth century, a merging of two vernacular African American musical styles—ragtime and blues—with elements of popular music.

Lehigh Valley

Over the centuries, strong ties of transport, investment, and culture grew between the Greater Philadelphia region and the Lehigh Valley.

Only in recent ⇒ Read More

Liberians and Liberia

Greater Philadelphia has had close links to Liberia historically.

Liberty Bell

It is America’s most famous relic, a nearly sacred totem. Several million people each year make a pilgrimage to see it, many dabbing their eyes as they gaze at it intently.

Four years later, much the same group institutionalized edification and self-improvement by establishing the ⇒ Read More

Lincoln Drive

The 4.1 miles of Lincoln Drive that link Philadelphia’s northwest neighborhoods to Center City was built in three distinct segments over the course of five decades in the late nineteenth and early twentieth centuries.

Literary Societies

Philadelphia’s literary societies typically have combined the social with the intellectual and artistic, with ongoing shifts in the balance between the two.

Philadelphia has often been described as a ⇒ Read More

Locomotive Manufacturing

For over one hundred and twenty years, railway locomotives were built in Greater Philadelphia.

Manufacturing Suburbs

Although early industrialization in the eighteenth century took root mainly in urban centers, a substantial share of the Philadelphia region’s early manufacturing sprang up in small towns outside the young city.

Redlining, the practice of basing access to capital and financial services on neighborhood characteristics such as race and ethnicity, had destructive effects on older, nonwhite areas of Philadelphia. Especially in areas of South, West, and Lower North Philadelphia that form a ring around downtown, banks and other lending institutions issued proportionally fewer mortgages than in ⇒ Read More

Refineries (Oil)

Philadelphia emerged as a petroleum hub in the second half of the nineteenth century. As an industrialized port city with global networks and extensive unbuilt land available on the Schuylkill and Delaware Rivers, the city offered the necessary rail and water infrastructure as well as access to water for the new industry. Extensive construction of ⇒ Read More

Religious Society of Friends (Quakers)

Much as New England was shaped by its Puritan heritage, the history of Philadelphia and the Delaware Valley intertwined heavily with the Religious Society of Friends. Philadelphia gained one of its nicknames, “The Quaker City,” from its founding and settlement by the Friends, colloquially known as Quakers, a historically Christian religious sect that emerged during ⇒ Read More

Restaurants

From colonial-era taverns to the celebrity chef establishments of the early twenty-first century, Greater Philadelphia’s restaurants illuminated the region’s socioeconomic, cultural, and culinary trends while also providing sustenance for millions, employing thousands, and in some cases emerging as historic and nostalgic treasures. Taverns and public houses (“pubs”) represented the area’s earliest food-serving establishments; many operated ⇒ Read More

Roman Catholic Education
(Elementary and Secondary)

Parochial schools in the Philadelphia region share a common Catholic mission and similar patterns of growth and development. For more than three centuries they have responded to the changing characteristics of the region’s Catholic population. Several of these developments, such as schools for specific ethnic groups, occurred in Philadelphia, Camden, N.J., and Wilmington, Del., within ⇒ Read More

Roman Catholic Parishes

Parishes stand at the center of Roman Catholic religious life. Since the arrival of Catholicism in the Philadelphia region in the early eighteenth century, parishes have shaped Catholics’ sense of communal identity by functioning as both the administrative unit of a diocese and the primary site of Catholic worship. Developing into expansive complexes that often ⇒ Read More

Roosevelt Boulevard

Snaking its way through parts of North and Northeast Philadelphia, the Roosevelt Boulevard, formally known as the Theodore Roosevelt Memorial Boulevard, has become one of the most heavily traveled thoroughfares in the Philadelphia metropolitan region. Initially conceived amid political maelstroms during the “corrupt and contented” phase of Progressive Era Philadelphia, “the Boulevard,” as it became ⇒ Read More

Root Beer

Root beer, a popular beverage in the United States since the late eighteenth century, began as a medicinal beverage produced at home. In the nineteenth century, carbonated root beer grew in popularity, particularly after Philadelphia pharmacist Charles Elmer Hires (1851-1937) presented his version of root beer at the 1876 Centennial Exhibition. Although the popularity of ⇒ Read More

Row Houses

Lining Philadelphia’s straight, gridiron streets, the row house defines the vernacular architecture of the city and reflects the ambitions of the people who built and lived there. Row houses were built to fit all levels of taste and budgets, from single-room bandbox plans to grand town houses. The row house was easy to build on ⇒ Read More

Saint Patrick’s Day

In March, Philadelphians of many backgrounds join together to celebrate Saint Patrick’s Day, the city’s Irish citizens, and their heritage. Celebrated in Philadelphia since 1771, the holiday began as a Catholic holy day and evolved into a rambunctious affair marked throughout the region by parades, music, dancing, drinking, and wearing kelly-green clothing to symbolize the ⇒ Read More

Salem County, New Jersey

Before Philadelphia’s founding, Salem, New Jersey, was the first English Quaker colony along the Delaware River. Established in 1675, the city of Salem had early prominence and served as a port of entry, but was soon overshadowed by Philadelphia. Although eighteenth-century settlement in Salem County consisted primarily of farmers and craftsmen, the proximity of the ⇒ Read More

Saturday Evening Post

The Saturday Evening Post, one of the oldest magazines in the United States, originated in Philadelphia in 1821 as a four-page weekly newspaper printed on the same equipment as Benjamin Franklin’s Pennsylvania Gazette. After switching to a magazine format in 1870, the Post grew in the twentieth century to reach more than a million readers ⇒ Read More

Savings Societies

The two most prominent forms of savings societies are the mutual savings bank and the savings and loan association, and Philadelphia is the home to the first institution for both. The Philadelphia Saving Fund Society (PSFS), founded 1816, and Oxford Provident Building Association, formed in 1831, were member-owned cooperatives whose success helped launch two financial ⇒ Read More

Saws and Saw Making

Philadelphia ranked as one of the nation’s foremost saw manufacturing centers for much of the nineteenth and twentieth centuries. Large-scale saw making began locally in the early nineteenth century, and by midcentury a number of major saw manufacturers operated in the city, including the world’s largest, Henry Disston’s Keystone Saw Works. Disston created a unique ⇒ Read More

Schuylkill Expressway

Fully opened for traffic November 25, 1958, Philadelphia’s Schuylkill Expressway was gridlocked from the first day of its operation. Envisioned by city planners as a panacea for economy-suffocating urban traffic congestion, but built on flawed engineering assumptions about traffic flows, the expressway ignored any concern for postwar social and regional realities. Rather than being acclaimed, ⇒ Read More

Schuylkill Navigation Company

While eighteenth-century Philadelphians looked almost exclusively to the east and the Delaware River to connect them to the wider world, by the turn of the nineteenth century they looked increasingly to the Schuylkill River and the west. After several failed attempts to fund improvements that would make the rapid-filled Schuylkill River navigable in the 1780s ⇒ Read More

Scientific Management

The “Scientific Management” movement was born in early twentieth-century Philadelphia factories but spread rapidly, transforming not only management techniques but also popular conceptions of industrialized society itself. According to its founders, the system simply sought the “one best way” to perform any task. But its time-study engineers, along with the assembly line, came to symbolize ⇒ Read More

Scientific Societies

Since the eighteenth century, Philadelphia-area scientific societies have promoted scholarship and innovation, increased access to scientific knowledge and played an important role in the professionalization of various disciplines. Longstanding institutions, including the American Philosophical Society (1743), the Academy of Natural Sciences (1812), and the Franklin Institute (1824), have garnered national and international accolades, while many ⇒ Read More

Scrapple

Scrapple, which came to the Philadelphia region from Germany, is a loaf of cooked pig parts thickened with cornmeal or buckwheat usually spiced with sage and pepper. Once cooled, the loaf is sliced, fried, and served as a breakfast side dish, often with syrup. Not just a culinary transplant, scrapple exists because of the interplay ⇒ Read More

Sesquicentennial International Exposition (1926)

In 1926, Philadelphia hosted the Sesquicentennial International Exposition, a world’s fair, to commemorate the one hundred and fiftieth anniversary of the signing of the Declaration of Independence. Although it opened to great fanfare, the exposition failed to attract enough visitors to cover its costs. The fair organization went into receivership in 1927 and its assets ⇒ Read More

Settlement Houses

The settlement house movement, a phenomenon of the Progressive era with origins in London, spread to Philadelphia in the 1890s as a large influx of needy immigrants and unsanitary conditions in the city attracted the attention of middle-class, college-educated reformers. Living among the poor in South Philadelphia, Kensington, and other neighborhoods, settlement house residents sought ⇒ Read More

Shipbuilding and Shipyards

Perhaps no business, industry, or institution illuminates the history of the Greater Philadelphia region from the seventeenth century to the present day more clearly than shipbuilding and shipyards. This may seem surprising since Philadelphia and nearby Delaware riverfront ports lie one hundred miles from the Atlantic Ocean up an often treacherous Delaware Bay and river ⇒ Read More

Shirtwaist Strike (1909-10)

On December 20, 1909, more than 7,000 of Philadelphia’s 12,000 shirtwaist workers walked out on their jobs, one month after the “uprising of 20,000” commenced in New York City’s shirtwaist industry. The strike lasted until February 6, 1910, when manufacturers agreed to comply with workers’ demands (though ultimately refused union recognition). Occurring in an era ⇒ Read More

Shopping Centers

Shopping centers, which bound retailers together into one physically convenient and accessible commercial venue for suburban consumers, profoundly altered Greater Philadelphia, redefining the region’s socioeconomic dimensions and destabilizing the city’s old, commercial core, the Central Business District. Commercial retailing also underwent significant changes, as the location, planning, and physical proportions of shopping facilities dramatically transformed ⇒ Read More

Shrines

People of faith have long revered significant religious sites, making pilgrimages for special devotion to locations that often developed into formal shrines–places regarded as holy because of their associations with sacred persons, relics, or events. Beginning in the mid-nineteenth century, Roman Catholic churches and other faiths in the Philadelphia area established a number of shrines, ⇒ Read More

Silk and Silk Makers

Philadelphia’s silk industry began in earnest in the early nineteenth century. There had been efforts since the early eighteenth century to cultivate the silk worm and establish silk-making operations in the region, but they had proven unsustainable or were carried out on a small scale. Philadelphia’s first successful silk manufacturer began operating in 1815, and ⇒ Read More

Single Tax Movement

During the Gilded Age and Progressive Era, Philadelphia helped give birth to the single tax movement, one of the country’s more influential, if less well-remembered, reform movements. The idea of a “single tax” on the unimproved value of land, rather than on productive activities, was popularized by Henry George (1839-97), a native of Philadelphia. The ⇒ Read More

Slinky

Invented by accident in a Philadelphia shipyard, the Slinky is a stack of coiled metal that becomes a bit of oscillating magic, a moving, traveling toy perfect for flipping head-over-heels to “walk” down stairs. Always made in Pennsylvania, the Slinky became standard-issue equipment for generations of American children and a familiar, fun plaything for grown-ups ⇒ Read More

Slovaks and Slovakia

Slovak migration to the Philadelphia region was no less a part of the Slovak experience in the United States than the larger Slovak migrations to Pittsburgh, Cincinnati, or Chicago. Although much smaller and often overlooked in larger migration accounts, Slovak-speaking workers contributed to Philadelphia’s reputation as a “Workshop of the World” through their contribution to ⇒ Read More

Smoking and Smoking Regulations

The origins of smoking tobacco in the Philadelphia region can be traced to the era before European colonization and evolved from pipes and cigars to the commercialization of cigarettes beginning in the late nineteenth century. Philadelphia-area farmers grew tobacco, local manufacturers produced cigars and cigarettes, and the N.W. Ayer advertising agency helped Camel cigarettes become ⇒ Read More

Soccer

Soccer has been played in the Philadelphia area since the late nineteenth century. The rules of Association football, known in the United States as soccer, were formulated in England in 1863. Various forms of football were played in Philadelphia before that time and after, but the first game of soccer in the city “under proper ⇒ Read More

Social Dancing

Dancing has been popular in Philadelphia since the city was founded, in spite of religious opposition, especially from Quakers. Far from succumbing to religious criticism, social dancing gained in importance as a way for socially ambitious Philadelphians to demonstrate their gentility. For most of the eighteenth and nineteenth centuries, well-to-do families gathered for formal balls ⇒ Read More

Society Hill

Society Hill is one of Philadelphia’s oldest neighborhoods, with more buildings surviving from the eighteenth and nineteenth centuries than any other in the country. Usually defined by the boundaries of Walnut, Lombard, Front and Eighth Streets, this area south of Independence National Historic Park evolved over the centuries as a diverse, complex residential and commercial ⇒ Read More

South Street

Along its east-west course, South Street has been a space where different types of Philadelphians—white and black, poor and wealthy, parochial and urbane, straight and gay—have met and mingled. From its early days as a theater district, it evolved through various incarnations: from a locus for African American life to a center for immigrant-owned garment ⇒ Read More

SPHAS

In 1917, a group of Jewish high school graduates in Philadelphia formed a basketball team that competed against other local teams. Affiliated with the Young Men’s Hebrew Association (YMHA) at first, the team soon became known as the SPHAS (South Philadelphia Hebrew Association) after the YMHA withdrew its sponsorship because it considered the sport too ⇒ Read More

Sports Cards

Sports card collecting, a classic American hobby, has strong ties to Philadelphia. Its history can be traced through Philadelphia firms such as the American Caramel Company, Fleer Corporation, and Bowman Gum Company. Those three, all pioneers and innovators in the sports card industry, helped to build collecting as a popular hobby. Sports cards developed from ⇒ Read More

Sprawl

Despite Philadelphia’s twenty-first century resurgence as the urban center of a vital multistate region, the city’s revival did not stem the tide of outward expansion in a largely uncontrolled pattern known popularly as “sprawl.” The steepest population growth in the region continued to occur in the newer suburbs and rural locales, in a low-density and ⇒ Read More

Stadiums and Arenas

The stadiums and arenas of the Greater Philadelphia region provide a physical venue not only for athletic contests, but also for Philadelphians’ passionate connection to their sports teams. Deeply embedded in regional identity and personal memories, the history of the area’s stadiums and arenas reflects broad patterns of regional development and change. During the 1860s ⇒ Read More

Street Vendors

From the colonial period to the present, street vendors have been integral yet contentious features of Greater Philadelphia’s economic landscape. Providing massive numbers of customers with food, clothing, and other goods while allowing many working people an occupational foothold in the region, vending also sparked controversies regarding taxes, regulation, public health, and uses of space. ⇒ Read More

Streetcar Suburbs

Beginning in the middle of the nineteenth century, Philadelphia’s growing streetcar network facilitated the movement of upper and middle class Philadelphians to residential districts outside of the urban core. New streetcar-centric suburban developments combined the allure of pastoral living with fast access to work and commerce in central Philadelphia. In this way, streetcar suburbs represented ⇒ Read More

Streetcars

For more than 150 years streetcars have served the Philadelphia area and helped Center City Philadelphia retain its commercial, retail, and entertainment supremacy in an ever-expanding region. Although the motive power switched from horses to electricity (with short detours into steam and cable), most change has been evolutionary rather than revolutionary. Perhaps the greatest transformation ⇒ Read More

Subway Concourses

Originally built by the Philadelphia Transit Company in the early twentieth century, the underground concourses in Center City Philadelphia played a crucial part in the construction of subway tunnels and then expanded into a network of private and publicly owned pedestrian walkways and storage facilities. In 1912, the City of Philadelphia assumed active development of ⇒ Read More

Subways and Elevated Lines

Philadelphia’s subway and elevated network consists of four lines that connect with other transportation options to serve much of the region. Although the network is relatively simple compared with systems in other cities, its history is complex. It took over eight decades to plan and to build, and its construction required a variety of public-private ⇒ Read More

Tastykake

“Nobody bakes a cake as tasty as a Tastykake” has been a brand tag line known by virtually every Philadelphian for a century. Indeed, few things are as iconically associated with the city and region as Tastykakes. The company was founded in 1914 by Philip J. Baur and Herbert T. Morris, in the Germantown neighborhood ⇒ Read More

Taverns

From small operations in the colonial era to elaborate social spaces in the twenty-first century, taverns in and around Philadelphia have been vital institutions, offering respite, nourishment, and camaraderie to travelers and patrons. Over time, attitudes and laws regarding the consumption of alcohol altered the character of the tavern and gave rise to modern hotels, ⇒ Read More

Telephones

The telephone revolutionized communications by allowing messages to be transmitted instantly to nearly anywhere in the world. Following the public debut of the device at the Centennial Exhibition of 1876, Philadelphia became home to many of telephony’s milestones and a center of telephone innovation, promoted by pioneers and supporters including inventor Alexander Graham Bell (1847-1922) ⇒ Read More

Television

SThe Philadelphia region had a key role in the ascent of television in American popular culture. From the manufacturing of television sets to the production of innovative programming, researchers, technicians, and creative talents in the region produced many of the “firsts” that propelled television to success as a new mass medium in the twentieth century. ⇒ Read More

Tenderloin

In the final decades of the 1800s, a vice district emerged just north of Philadelphia’s city center. Bound by Sixth Street on the east, Thirteenth Street on the west, Race Street to the south, and Callowhill Street to the north, this neighborhood was called the Tenderloin, like similar districts in many other cities of the ⇒ Read More

Textile Manufacturing and Textile Workers

Textile manufacturing began in Philadelphia soon after the city’s founding in 1682 and grew to be one of its chief industries. By the turn of the twentieth century Philadelphia was one of the world’s greatest textile manufacturing centers, with tens of thousands of workers making a wide range of products. The industry declined dramatically in ⇒ Read More

Thanksgiving

Although inspired by a 1621 feast shared by Pilgrims and Native Americans in Plymouth, Massachusetts, Thanksgiving traditions emerged from more than two centuries of celebrations influenced by social classes, ethnic groups, and the rise of consumer culture. Some of the most popular practices of Thanksgiving by the twenty-first century originated in Philadelphia. In colonial America, ⇒ Read More

Thrift

Philadelphia became a national center for the thrift movement of the late nineteenth and early twentieth centuries as a high concentration of progressive individuals and institutions promoted values of frugality, industry, and stewardship as a means for poor and working-class people to improve their circumstances. Espoused by white middle-class society, the thrift movement declined when ⇒ Read More

Tobacco

Growing, trading in, and manufacturing tobacco were important components of the economy and society of the Delaware Valley for centuries. Early residents raised tobacco for personal use and as a trade commodity, but in most of the region it fell out of favor by the late eighteenth century. The exception was Southeast Pennsylvania, where tobacco ⇒ Read More

Tomato Pie

Served by Italian bakeries in South Philadelphia since the early twentieth century, the tomato pie became known by many names: church pie, square pizza, red pizza, granny pizza, and red pie. Although made in a rectangular or square shape similar to Sicilian-style pizza, tomato pie within the city and surrounding region remained distinct from contemporary ⇒ Read More

Tourism

Philadelphia has been a tourist destination since leisure travel emerged as a common pastime for the middle and upper classes in the nineteenth century. By the twenty-first century, the region’s economy depended heavily on tourism to Philadelphia and nearby destinations such as the Brandywine Valley, Valley Forge, and the Jersey and Delaware shores. Historic sites ⇒ Read More

Toy Manufacturing

Philadelphia helped define the toy industry in the United States with simple yet engaging toys that became beloved by generations. Although social, cultural, and economic changes produced challenges for the industry, a few iconic toys stood the test of time and continued to promote imagination, creativity, and discovery for people of all ages. Philadelphia’s first ⇒ Read More

Trails (Recreational)

An expanding network of recreational paths for walkers, hikers, cyclists, joggers, and commuters serves the Greater Philadelphia region. The first recreational paths date to the mid-nineteenth century, when upper-class residents sought idyllic walking grounds in rural cemeteries and urban parks. In the twentieth century, grassroots hiking clubs built additional footpaths, but by the early twenty-first ⇒ Read More

Trees

Trees have been culturally, environmentally, and symbolically significant to the Philadelphia region since the city’s founding. They were believed to improve public health, they beautified and refined city streets, parks, and other green spaces, and several were revered as living memorials to past historical events. Trees also faced their fair share of destruction during the ⇒ Read More

Typhoid Fever and Filtered Water

Philadelphia in the late nineteenth century stood shamefully high among large American cities in rates of death from typhoid fever (also known as enteric fever). Caused by a type of Salmonella bacterium, the disease had become common in Philadelphia and other cities with crowded populations, inadequate disposal of human waste, and lack of water treatment. ⇒ Read More

Union League of Philadelphia

The Union League of Philadelphia, organized in 1862 as a political club for the support of the Union cause during the Civil War, developed into the premier urban social club of Philadelphia. Over time, it also became an important supporter of Republican political candidates and policies locally and nationally, acquired a significant collection of art ⇒ Read More

United States Mint (Philadelphia)

Coins have been minted in Philadelphia as long as the federal government has produced legal tender coins. First authorized by Congress in 1792, the U.S. Mint’s Philadelphia facility (commonly known as the Philadelphia mint) in the early twenty-first century remained the nation’s largest producer of coins. Its history has been intertwined with the complicated history ⇒ Read More

Vagrancy

Vagrancy, generally defined as the act of continuous geographical movement by the poor, often has been interpreted to signify idleness, unemployment, and homelessness. Since the colonial era, it has been a driving social concern in the Mid-Atlantic region, where urban centers, including Philadelphia, attracted poor migrants seeking new economic prospects. Laws created to aid them ⇒ Read More

Veterans and Veterans’ Organizations

Military veterans began organizing in the Philadelphia area during the waning days of the Revolutionary War. As the Continental Army disbanded, its veterans often met at City Tavern and the first general meeting of America’s first veterans’ organization, the General Society of the Cincinnati, occurred there on May 4, 1784. Just as regularly, however, veterans ⇒ Read More

Vine Street Expressway

The Vine Street Expressway (Interstate 676), a 1.75-mile depressed limited-access highway traveling east-west across the northern edge of Philadelphia’s central business district, resulted from more than sixty years of effort to connect I-95 and I-76 and move traffic more easily between and through the city to surrounding counties in Pennsylvania and New Jersey. Its route ⇒ Read More

Walking Encyclopedia: Harrowgate

Like many neighborhoods in Philadelphia, Harrowgate, located just northwest of Kensington, experienced dramatic changes as a result of the industrial boom in the nineteenth century. Prior to industrialization, Harrowgate was a small community built around medicinal springs and attracted only the wealthiest of Philadelphia’s citizens. Industrialization, however, transformed Harrowgate. By the late nineteenth century, Harrowgate ⇒ Read More

West Chester, Pennsylvania

Boosted by its strategic location some twenty-five miles from Philadelphia, West Chester, Pennsylvania, grew and prospered for most of its history as the county seat of Chester County. Pressured by mid-twentieth-century suburbanization, the borough lost its commercial and residential dominance and even its role as county seat somewhat diminished as the growth of the surrounding ⇒ Read More

West Philadelphia

One of the single largest sectors of the city of Philadelphia at almost fifteen square miles between the Schuylkill River to the east and Delaware County to the west, West Philadelphia at its peak, in the early twentieth century, attracted an influx of new residents to its verdant, suburban-feeling neighborhoods. But over the course of ⇒ Read More

Woman Suffrage

While the Philadelphia region often led the way on progressive reforms, by the twentieth century, woman suffrage was not among them. The region boasted a number of early woman suffrage advocates, and women in New Jersey had the right to vote during the early years of the republic, but by the late nineteenth century, Pennsylvania ⇒ Read More

Woman’s Medical College of Pennsylvania

The Woman’s Medical College of Pennsylvania, founded in 1850 as the Female Medical College of Pennsylvania, was the first medical school in the world for women authorized to award them the M.D. It was established in Philadelphia by a group of progressive Quakers and a businessman who believed that women had a right to education ⇒ Read More

Women’s Clubs

The woman’s club movement began throughout the United States in the late nineteenth century. Although initially focused on self-improvement, women’s clubs in the Philadelphia region as in the nation quickly extended their goals to include community activism. Drawing upon contemporary assumptions about the inherent differences between men and women, leaders of the club movement argued ⇒ Read More

Women’s Education

As home to the first chartered school for girls in the United States, the country’s first medical college for women, one of the earliest chapters of the American Association of University Women (AAUW), and coeducational and women’s colleges, the Philadelphia region provided pioneering models in women’s education. These innovations operated in the context of national ⇒ Read More

Woodbury, New Jersey

Located on the Woodbury Creek in the northwestern part of Gloucester County, Woodbury formed as a result of the first Quaker family to settle the area, in 1683. Initially a lightly populated farming community, the village eventually became the seat of Gloucester County and over time emerged as an important center for transportation, manufacturing, and ⇒ Read More

Works Progress Administration (WPA)

In response to the rising tide of unemployment nationally, and after the short-lived Civil Works Administration (CWA) failed to stem that tide, Congress in May 1935 created the Works Progress Administration (WPA), one of the “alphabet soup” of economic recovery programs enacted as part of the New Deal of President Franklin D. Roosevelt (1882-1945). Later ⇒ Read More

Workshop of the World

How will they know? How will future generations of Philadelphians have any inkling that their city once thrived as a premier manufacturing center, the fine products issuing from its shops, mills, and plants prized by customers around the nation and the world? There are few traces left of this history—abandoned factory buildings here and there—and ⇒ Read More

World War I

Although the United States’ military involvement in the First World War lasted just over a year, the conflict in Europe had a lasting impact on the Philadelphia region. The war created new opportunities for the industrial base of Philadelphia, Chester, and Camden, and as men and women enlisted for military service, the region developed a ⇒ Read More

World War II

World War II, which created change for industries, populations, and politics in many urban areas in the United States, had a transforming effect on the Philadelphia region. Already industrialized, the region gained new impetus from government orders for supplies, armaments, transportation, and more. Philadelphia-area industries expanded, making the region a major “arsenal for democracy” during ⇒ Read More

Zoning (Philadelphia)

From its inception, zoning became a fraught subject. By empowering neighborhood groups and local politicians with power over land use in their communities, zoning brought such groups in Philadelphia and elsewhere into contest with developers, industrial concerns, and sometimes with other people who wanted to move into their neighborhoods. The policy generated results both noble, ⇒ Read More
