Dr. Marvin Fox (1910-1965) was an American physicist. As a Ph.D. student at Columbia University, Fox worked with Isidor Rabi and Harold Urey, with whom he collaborated on isotope separation studies.
In 1942, Fox was recruited to join the Radiation Laboratory (“Rad Lab”) at MIT. In 1944, he joined the Manhattan Project at Columbia. After the war, he served as Chairman of the Reactor Department at Brookhaven National Laboratory, where he helped build the first reactor dedicated to peaceful uses of atomic energy.
Marvin’s son, David Fox, was five years old when Japan attacked Pearl Harbor. An interview with David about his father’s work on the Manhattan Project can be found here.
