From its initial, colonial foundations as a sparsely populated farming hinterland to its dramatic postwar housing development after World War II, Northeast Philadelphia developed into a desirable destination for those seeking to improve their economic, social, and cultural standing within Philadelphia’s city boundaries. Stretching from Frankford in the lower Northeast to Somerton in the Far Northeast, its vast, geographic expanse has undergone dramatic spatial, economic, and racial transformations throughout its complex and still unfolding history.

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

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

Coal
In the nineteenth century, Philadelphia banks and entrepreneurs played a pivotal role in facilitating the emergence of coal as the nation’s principal energy source for industry, transportation, and heating, by creating and financing the firms that first brought to market anthracite coal, mined exclusively in rugged eastern Pennsylvania. To mine anthracite, or “hard coal,” on ⇒ Read More

Consolidation Act of 1854
The Consolidation Act of 1854 extended Philadelphia’s territory from the two-square-mile “city proper” founded by William Penn to nearly 130 square miles, making the municipal borders coterminous with Philadelphia County and turning the metropolis into the largest in extent in the nation, a position it held until Chicago leapt ahead in 1889. Consolidation’s supporters believed ⇒ Read More

Down There
Down There, a hardboiled crime novel by Philadelphia writer David Goodis (1917-67) published in 1956, follows Eddie Lynn, a former concert pianist, who hides from his past until his estranged brother shows up and forces him to grapple with his ghosts. Although not one of Goodis’s most successful novels, Down There became his most famous ⇒ Read More

Environmental Movement
With its industrial past and expanses of natural resources, the Greater Philadelphia region teemed with activity during the environmental movement of the late twentieth and early twenty-first centuries. In the years following World War II, people across the United States began to demand new measures to assure their health and safety. The resulting environmental movement, ⇒ Read More

Genealogy
In the Delaware Valley and the United States, the study of genealogy transformed from a pursuit of the elite in the nineteenth century into the most democratic field of historical research. The search by genealogical researchers for materials of importance that assist with pedigree building, family histories, and searches for heirs has resulted in the ⇒ Read More

I-95
Interstate 95—known as the Delaware Expressway in the Philadelphia area—is one of the region’s key transportation conduits. Running alongside the western bank of the Delaware River, it links central Philadelphia with Mercer County in New Jersey and Bucks and Delaware Counties in Pennsylvania. Conceived and built in an era when planners promoted automobile traffic above ⇒ Read More

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. Compact industrial neighborhoods originated at a time when the lack of public transportation made it necessary for workers to live within walking distance of the factories. These row house blocks ⇒ Read More

Liberty County
City and state politicians representing Northeast Philadelphia, deeply unsettled by the shifting economy and demographic makeup of the city in the 1980s, proposed seceding to create “Liberty County,” a separate, suburban municipality to ostensibly address taxpayers’ demands for improved municipal services. The primary impetus for such a radical step, however, was reaction to Philadelphia’s first ⇒ Read More

Machining and Machinists
Hundreds of machine shops, large and small, built and maintained Philadelphia’s position as the “Workshop of the World” through the nineteenth and twentieth centuries. In the city and beyond, especially in Conshohocken, Pottstown, Phoenixville, Chester, and Camden, machining made the Delaware Valley a hub of foundries, craft shops, mills, workshops, and manufactories. During the latter ⇒ Read More

Mexican-American War
Despite taking place in the American Southwest and Central America, the Mexican-American War (1845-48) had significant ties to the Philadelphia area. As one of the most populous urban centers in the country, the Delaware Valley became a hotbed of activity for one of the most controversial wars in American history. War between the United States ⇒ Read More

Northeast Philadelphia
From its initial, colonial foundations as a sparsely populated farming hinterland to its dramatic postwar housing development after World War II, Northeast Philadelphia developed into a desirable destination for those seeking to improve their economic, social, and cultural standing within Philadelphia’s city boundaries.

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

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

Surveying (Colonial)
Land was the most valuable commodity in the Delaware Valley during the colonial period, and it had to be surveyed before it could be granted or transferred. In Pennsylvania, William Penn (1644–1718) relied upon surveyors to measure and map his new lands. Colonial surveyors established tract, manor, township, and county boundaries, laid out city streets ⇒ 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
