E. Paul du Pont (1887-1950) established Du Pont Motors, Inc., a manufacturing company of luxury automobiles, in 1919 in Wilmington, Delaware. He worked for a short time at the family business, E.I. du Pont de Nemours & Company which manufactured gunpowder. He was one of ten children of Francis Gurney du Pont (1850-1904) and Eliza Wigfa Simons du Pont (1849-1919). This small collection contains photographs of DuPont powder yards; family photographs; home exteriors; and postcard views of Longwood Gardens.

Charles Copeland (1867-1944) was Secretary of E.I. du Pont de Nemours and Company from 1921 to 1935. He also served on the Board of Directors from 1921 to 1942. This small collection primarily consists of scenic views of the Hagley property. The collection has been organized into three series: Brandywine and Hagley areas of Copeland estate; Rolling wheels, and Pierre Gentieu prints.

Pierre A. Gentieu (1842-1930) was a long-time employee of E.I. du Pont de Nemours & Company. Gentieu was born in France in 1842. He emigrated to the United States around 1859. He began working for DuPont in 1877. This collection is comprised of images taken by DuPont Company employee Pierre Gentieu from approximately 1880 to 1920. Gentieu's images document the DuPont Company Powder Yards along the banks of the Brandywine River in Wilmington Delaware. The collection documents the surrounding community along the Brandywine including worker's families, du Pont family homes, churches in the area, DuPont Company exposition displays, and other facets of social and work life in the area.
