Francis Gurney du Pont (1850-1904) was the youngest son of Alexis I. du Pont (1816-1857) and Joanna Smith du Pont (1815-1876), and grandson of Éleuthère Irénée "E.I." du Pont (1771-1834), founder of E.I. du Pont de Nemours & Company, a chemical company more commonly referred to as the DuPont Company. The papers consist of du Pont's student lecture and laboratory notes; letters; technical notes and papers; records of gunpowder production; patent specifications and drawings; patent correspondence; and printed patents related to gunpowder.

The pulp keg mill was built around 1904 to manufacture an experimental design of black and smokeless powder container made essentially from paper. This album contains photographic prints of the construction of the pulp keg mill in the Hagley Yard of E.I. du Pont de Nemours & Co. near Wilmington, Delaware around 1902 through 1905.
