On 2 December 1942, a pivotal moment occurred at CP-1. Enrico Fermi led the world's first self-sustaining nuclear chain reaction, a remarkable achievement. The reactor's construction took place under Stagg Field's west viewing stands by the talented team from the University of Chicago's Metallurgical Laboratory.
