Stagg Field

Amos Alonzo Stagg Field is the name of two different football fields for the University of Chicago. The earliest Stagg Field (1893-1957) is probably best remembered for its role in a landmark scientific achievement by Enrico Fermi during the Manhattan Project. The site of the first nuclear reaction received designation as a National Historic Landmark on February 18, 1965. On October 15, 1966, which is the day that the National Historic Preservation Act of 1966 was enacted creating the National Register of Historic Places, it was added to that as well. The site was named a Chicago Landmark on October 27, 1971. A Henry Moore sculpture, Nuclear Energy, in a small quadrangle commemorates the location of the nuclear experiment. The University's current Stagg Field is located a few blocks away and reuses one of the original gates.

Chicago Pile-1, the world's first artificial nuclear reactor, was built under the west stands of Stagg Field, which was no longer used for football. The first man-made self-sustaining nuclear chain reaction occurred on December 2, 1942.

The first Stagg Field was a stadium at the University of Chicago in Chicago, Illinois. It was primarily used for college football games, and was the home field of the Maroons. Stagg Field originally opened in 1893 as Marshall Field, named after Marshall Field who donated land to the university to build the stadium. In 1913, the field was renamed Stagg Field after their famous coach Amos Alonzo Stagg. The final capacity, after several stadium expansions, was 50,000. The University of Chicago discontinued its football program after 1939 and left the Big Ten Conference in 1946. The stadium was demolished in 1957, and much of the stadium site was re-utilized as the site of Regenstein Library.
