Crawford H. Greenewalt (1902-1993) was an executive with the DuPont Company and president of the firm from 1948 to 1962. In 1942, when the DuPont Company agreed to participate in the Manhattan Project, Greenewalt was named chief liaison, working with the physicists at the University of Chicago Metallurgical Laboratory, including Arthur Compton (1892-1962) and Enrico Fermi (1901-1954), who were developing techniques for plutonium separation. The collection consists of eight volumes of Greenewalt's diaries, which describe the history of the Manhattan Project and the development of the United States' first atomic bombs that were used to end the Second World War. The diaries describe the technical history of the project, as well as the relationships that developed between scientists.

Donald Fell Carpenter (1899-1985) was general manager of the Film Department at the DuPont Company. He graduated from the Massachusetts Institute of Technology (MIT) with a degree in engineering in 1922. Between 1927 and 1933 he held increasingly important managerial positions with the DuPont Viscoloid Company, and between 1933 and 1948 with the Remington Arms Company. In 1947 to 1948 he was a member of the Industrial Advisory Group to the U.S. Atomic Energy Commission. Broadly speaking, the materials in this small collection of his papers cover Carpenter's entire career, from his senior thesis at MIT (the design for an addition to his father's tinsmithing shop) to his involvement with political and civic affairs during his retirement.

Richard Douglas Caney (1918-1994) was a chemical engineer with E.I. du Pont de Nemours & Company, working in the Explosives Department on the Manhattan Project. To remember his participation in the Manhattan Project, Caney prepared a scapbook of newspaper clippings of articles that flooded the media after the atomic bombs were dropped and the secrecy around the project ended.
