Italian-American physicist Enrico Fermi created the first self-sustaining nuclear chain reaction demonstration on December 2, 1942 at the Metallurgical Laboratory of the University of Chicago, Chicago, IL, USA for a 40 person audience. Neutrons, spontaneously released by atoms of metallic uranium that were embedded in a suitable pattern throughout a block of graphite, collided with neighboring atoms of uranium oxide, causing these atoms to split. The split atoms released additional neutrons, causing multiple reactions with other uranium atoms at a rapidly increasing rate.

Chicago Pile-1 (CP-1) was the world’s first artificial nuclear reactor. On 2 December 1942, the first human-made self-sustaining nuclear chain reaction was initiated in CP-1, during an experiment led by Enrico Fermi. … Fermi described the apparatus as “a crude pile of black bricks and wooden timbers”.
