David Fox’s father, Dr. Marvin Fox, studied physics at Columbia University under Isidor Rabi and Harold Urey. Marvin Fox worked at the Radiation Laboratory at MIT and at Columbia during the Manhattan Project. After the war, he served as Chairman of the Reactor Department at Brookhaven National Laboratory, where he helped build the Graphite Research Reactor, the first reactor dedicated to peaceful uses of atomic energy. In this interview, David Fox describes his father’s work on the Manhattan Project and at Brookhaven, his idealism about technology, and how the onset of the Cold War affected him.
Dr. Alfred Nier was an American physicist well-known for his work on spectrometry. Nier designed the mass spectrometers used for Manhattan Project experiments and his instruments were sent to all of the major Project sites. With his mass spectrometer, Nier helped prove that that U-235 was fissile, not the more abundant isotope U-238. Nier worked for the Kellex Corporation to design and construct the apparatuses used to monitor the separation of Uranium-235 and Uranium-238, as well as leak detectors for the K-25 gaseous diffusion plant. In this interview, Nier discusses his early involvement in the Manhattan Project in New York and the transport of uranium between Project sites. He also discusses his experiences working at both the Nash Garage Building in New York City, and the K-25 Plant at Oak Ridge, Tennessee.
