E.I. du Pont de Nemours & Company was organized in Paris in 1801 by Pierre Samuel "P.S." du Pont de Nemours (1739-1817) and his son Eleuthère Irénée "E.I." du Pont (1771-1834) for the manufacture of gunpowder. Included here are records of the firm collected by P.S. du Pont and separated from the main body of company records.

William du Pont (1855-1928) was an industrialist and member of the promienent du Pont family of Delaware, whose family business was the E.I. du Pont de Nemours & Company, also known as the DuPont Company which was a large manufacturer of gunpowder. He worked for the first DuPont dynamite manufacturer, Repauno Chemical Company, as secretary and treasurer (1880-1884) and after the tragic death of Lammot du Pont (1831-1884), as president (1884-1892). This small group of papers encompass both correspondence and various financial and investment accounts, largely covering his ten years spent in England after leaving the United States in 1893.
