Dorothy J. Sorensen (1923-2006) was an employee of E.I. du Pont de Nemours & Co., a chemical company commonly known as the DuPont Company. She served in the Women Air Force Service Pilots (WASPs) during World War II as an aircraft instrument technician, instructing others in the repair and maintenance of aircraft tools and instruments. The WASPs contributed to the war effort by helping to train pilots for the first atomic mission as the delivery system for the Manhattan Project; the development of the B-29 Silverplate started as a way of carrying atomic bombs for specialized bombing missions. These two items are a Certificate of Appreciation from the U.S. War Department, Manhattan District, and a Manhattan Project Atomic Bomb pin that Sorensen received on August 6, 1945.
