The first Stagg Field was a stadium at the University of Chicago in Chicago. 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 used as the site of Regenstein Library.
