About Us

Welcome to Hagley Museum and Library!

Located on 235 acres along the banks of the Brandywine in Wilmington, Delaware, Hagley is the site of the gunpowder works founded by E. I. du Pont in 1802. This example of early American industry includes 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. Hagley Library is a proud member of the prestigious Independent Research Libraries Association (IRLA). Click here for more information about the Library.

The Library’s Center for the History of Business, Technology, and Society organizes and administers the Hagley Museum and Library's interaction with the world of scholarship. It brings attention to Hagley's research collections and generates intellectual dialogue at Hagley.
