Moore sculpture
Henry Moore's sculpture Nuclear Energy bears the caption: "On December 2, 1942, man achieved here the first self-sustaining chain reaction and thereby initiated the controlled release of nuclear energy." Under the leadership of Enrico Fermi, Chicago Pile No. 1 (CP-1) was constructed in a makeshift laboratory under the grandstands of Stagg Field Stadium at The University of Chicago. The sculpture was unveiled at 3.36 p.m. on 2 December 1967, precisely a quarter of a century after the event that it commemorates.
