E.I. du Pont de Nemours & Company is a chemical company that began as a gunpowder manufacturer in 1802. In 1939, the DuPont Company created the Seaford Plant near Seaford, Delaware, to be the world's first nylon plant. The bulk of the records in this collection relate to the planning of the Seaford Plant's 50th anniversary celebration events; however, there is a small amount of documentation related to the introduction of nylon, as well as operation and wage statistics from the 1940s through the 1960s that would be of interest to researchers interested in textiles, manufacturing, or labor practices.
