E.I. du Pont de Nemours is a chemical company commonly known as the DuPont Company. It was established in 1802 and began by manufacturing gunpowder; later it moved to chemical compounds. The foundations for the Engineering Department were laid in 1902. The department's purpose was to design and construct high explosives plants, design powder machinery, and create extensions to existing plants. The collection consists of three mechanical drawings created by the DuPont Company's Engineering Department showing specifications for constructing and marking crates for gelatine dynamite.
