Hagley Museum and Library collects, preserves, and interprets the unfolding history of American enterprise. Hagley’s collections document the interaction between business and the cultural, social, and political dimensions of our society from the late 18th century to the present.

Located on 235 acres along the banks of the Brandywine River in Wilmington, Delaware, Hagley is the site of the gunpowder works founded by E. I. du Pont in 1802. It is an example of early American industry including restored mills, a workers' community, and the ancestral home and gardens of the du Pont family.

Hagley's library furthers the study of business and technology in America. The collections include individuals' papers and companies' records ranging from eighteenth-century merchants to modern telecommunications and illustrate the impact of the business system on society.

The Hagley library has allowed this site the use of approximately 200 photos of the Haskell plant. These include views of the plant, it's assorted manufacturing and storage structures, as well as repair and maintenance facilities, housing and infrastructure. These photos reveal the development of what is now the better part of the haskell section of Wanaque.

Postcard image (left) describing the "DuPont Club House" (about 1910), now part of Arrow Group Industries, Third Ave., Haskell.

At it's height, about 1914, the DuPont plant employed thousands of men and women. Homes were built, and many were housed local hotels, barracks and women's dormitories. Some of the homes built can be seen on the Haskell pages.
