E.I. du Pont de Nemours & Company is a chemical company more commonly referred to as the DuPont Company. It was organized in Paris in 1801 by Pierre Samuel du Pont de Nemours and his son Eleuthère Irénée du Pont and originally produced gunpowder.

In the years leading up to the Second World War, the United States government initiated a massive effort to ensure that adequate supplies of essential materials would be readily available should the country's armed forces become actively engaged in military conflict. At the request of the Army Ordnance Department, the DuPont Company participated in these procurement programs by undertaking the design, construction, and operation of plants for the manufacture of military explosives and other chemical products essential to the successful prosecution of the war. The records of the Explosives Department consist of special reports to the Executive Committee, the files of general manager Edward B. Yancey, and the files of powder superintendent Charles E. Seymour.

The Indiana Ordnance Works was built by the DuPont Company for the U.S. Government beginning in 1940. It manufactured military explosives, propellants, and smokeless powder. This collection consists of photographs of the Ballistics Lab of the Indiana Ordnance Works.
