Hagley’s Museum Collection contains more than 65,000 artifacts. Its beginnings go back to the donation of the DuPont Museum Collection in 1954 which focuses on innovations produced by the company including nineteenth century improvements in gunpowder and explosives as well as twentieth century innovative products such as Pyralin, Cellophane, nylon, Dacron®, Orlon, Kevlar® and more.

A very large United States patent model collection, numbering close to 5,000, reflects nineteenth century American inventions and innovations. Other collections at Hagley reflect the du Pont family and powder workers who owned, managed and worked at the Hagley site.

Only a very small percentage of the collection is on display at any time. If you wish to examine an object listed as not on display, please schedule an appointment at least two weeks in advance in order for staff to pull objects out of storage for the visit.

For questions about the collection, please contact Museum Registrar Keith Minsinger at or by phone at (302) 658-2400 extension 309.

For inquiries related to donating objects to the collection, please contact Curator of Collections and Exhibits Debra Hughes at or by phone at (302) 658-2400 extension 308.
