E.I. du Pont de Nemours & Company is a chemical company more commonly referred to as the DuPont Company. The company was established in 1802 by Pierre Samuel du Pont de Nemours (1739-1817) and his son Éleuthère Irénée du Pont (1771-1834); the company began with the production of gunpowder. The du Pont’s purchased a mill site on the banks of the Brandywine River just North of Wilmington, Delaware. During wartime the company was a major supplier for the United States government. During peacetime, the company marketed their product towards sportsmen and hunters. Throughout the 1900s and 1910s, the company shifted its focus away from gunpowder production and towards chemistry innovations. By 1926 the company officially dissolved the powder production unit, although it had already been inactive for many years.
