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. Linked to the Philadelphia port from the eighteenth century onward, the eastern part of the county, including Chester and its neighboring municipalities along the Delaware River, was almost indistinguishable from nearby Philadelphia neighborhoods while much of the rest of the county remained agricultural into the late twentieth century. In the mid-nineteenth century, the introduction of regional railways fostered new town centers at commuter stations. The westernmost section remained predominantly rural until the late twentieth century, when the county began to experience the effects of large-scale development. That mixed settlement pattern created some of the widest social disparities observable in any suburban county in the Philadelphia metropolitan area.

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
Brownfields Redevelopment
First designated by the U.S. Environmental Protection Agency (EPA) in 1995, the polluted tracts of land known as “brownfields” resulted from Greater Philadelphia’s industrial heritage. For more than a century, manufacturers generated vast amounts of waste and runoff. After industry declined between the 1950s and the 1980s, acres of abandoned structures and soiled land remained. ⇒ 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.

Courthouses (County)
The prominent locations of courthouses in the architectural landscape of Philadelphia and the surrounding region mirrored their positions as cornerstones of civic life.

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

Log Cabins
The Philadelphia region served as an important diffusion ground for log cabins in America as Swedes, Finns, and later Germans transposed their traditional building practices to the Delaware Valley, melding old-world models with the bounty of timber but adapting to the lack of tools and skilled craftsmen. By the mid-nineteenth century, log cabins had become ⇒ Read More

Public Health
From the moment Native Americans, Europeans, and Africans came together in the Delaware Valley, they confronted a host of health threats. Philadelphia’s earliest public health efforts reflected the lack of scientific understanding of infectious diseases, and usually began only after an outbreak commenced. After the terrible 1793 yellow fever epidemic, Philadelphia’s leaders founded a permanent ⇒ Read More
Railroad Suburbs
As railroads reached outlying villages and the countryside around Philadelphia during the nineteenth century, railroad companies and other enterprising real estate developers created fashionable residential enclaves, new suburban towns, and vast semirural estates.
