What other reactor did the supervisor of construction of the reactor that went critical under the supervision of Enrico Fermi build?
Chicago Pile-1 Chicago Pile-1 (CP-1), was the world's first artificial nuclear reactor. Its construction was part of the Manhattan Project, the Allied effort to create atomic bombs during World War II. It was built by the Manhattan Project's Metallurgical Laboratory at the University of Chicago, under the west viewing stands of the original Stagg Field. The first human-made self-sustaining nuclear chain reaction was initiated in CP-1 on 2 December 1942, under the supervision of Enrico Fermi, who described the apparatus as "a crude pile of black bricks and wooden timbers".
Frederic de Hoffmann Frederic de Hoffmann (b. Vienna, July 8, 1924 – d. La Jolla, October 4, 1989) was a nuclear physicist who worked on the Manhattan Project. He came to the United States of America in 1941 and graduated from Harvard in 1944. Upon graduating, de Hoffmann was sent to Los Alamos National Laboratory where he assisted Edward Teller in the development of the Hydrogen bomb. Frederic de Hoffmann was an advocate of peaceful atomic energy.
