Dr. Norman Hilberry was a physicist and the right-hand man to Arthur H. Compton at the Metallurgical Project (Met Lab) in Chicago. In the interview, Hilberry discusses the role he played as the Associate Project Director in Chicago. He elaborates on the process of obtaining large amounts of graphite, which was desperately needed, and extracting uranium metal. Hilberry also stresses the various and important roles played by corporations in the project.
Robert Holmberg began working on the Manhattan Project at the Chicago Met Lab and at Ames Laboratory in Iowa. He was then drafted into the Special Engineer Detachment and sent to Oak Ridge. He describes his life at Oak Ridge, where he met his wife and settled down, and recalls what he and his colleagues thought of General Leslie Groves at the time.
Fred Vaslow, a physical chemist, began working on the Manhattan Project while a graduate student at the University of Chicago. During his time working on the project, Vaslow worked in several of the secret cities, including Los Alamos alongside J. Robert Oppenheimer. Vaslow shares many insights including the general opinion about the bomb among scientists who had contributed to its creation as well as the spreading denigration of Oppenheimer’s character after the bombs were dropped.
