Bill Mackey (1906-1996) was a chemical engineer and the plant manager of the Technical Division of the Explosives Department of the E.I. du Pont de Nemours & Company. His papers consist of a mix of personal and DuPont Company materials documenting his career as an explosives expert.

The E.I. du Pont de Nemours is a chemical company commonly known as the DuPont Company was established in 1802, and began by manufacturing gunpowder and later 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 DuPont Engineering Department collection consists of photographic material documenting Twentieth century construction projects throughout the many different E.I. du Pont de Nemours and Company work sites, including some outside construction projects within the explosives and chemical industry. There are 209 work sites which are arranged in alphabetical order.

E.I. du Pont de Nemours & Company is a chemical company more commonly referred to as the DuPont Company.

In 1902, DuPont took control of Laflin & Rand, including the Haskell Works. Infallible and Ballistite powders were manufactured there. The works played an important role in smokeless powder production during World War I. The panoramic photographs depict views of the Du Pont Company's smokeless powder works in Haskell, New Jersey and the workers village nearby.

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.
