Edward B. du Pont (1934-2017) was vice president of the Wilmington Trust Company, served on numerous boards of directors, and was descended from the founders of E.I. du Pont de Nemours & Company, a chemical company more commonly referred to as the DuPont Company. This small collection documents Edward B. du Pont's service on the boards of directors for the DuPont Company, Atlantic Aviation, and the Hagley Museum and Library, as well as the board of trustees for the University of Delaware, primarily through group portraits. His work for the DuPont Company is most heavily represented. The collection is arranged chronologically. The majority of images date from 1977 to 2003.

Eugene du Pont Jr. (1873-1954) was a director of the E.I. du Pont de Nemours & Company from 1917 until 1954, and a great grandson of company founder, Éleuthère Irénée du Pont (1771-1834). The papers of Eugene du Pont Jr. include reports to the DuPont Company Board of Directors by the executive committee and the treasurer of the DuPont Company. In addition, there are several copies of letters to du Pont family members.
