“On December 2, 1942 using a nuclear reactor erected under a section of the West Stands of the University of Chicago’s Stagg Field, a group of scientists achieved the first self-sustaining chain reaction and thereby initiated a controlled release of nuclear energy. The reactor consisted of uranium and uranium oxide lumps spaced in a cubic lattice embedded in graphite. In 1943, the reactor was dismantled and reassembled at the Argonne National Laboratory.” (University of Chicago Library)
