Crawford H. Greenewalt's Manhattan Project laboratory notebooks

About this collection

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 seven volumes of Greenewalt's notebooks, with corresponding typescripts, 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 notebooks describe the technical history of the project, as well as the relationships that developed between scientists. Click here for a detailed description of the collection.
