The University of Chicago (also called Chicago University and, after it closed, Old University of Chicago) was a college affiliated with the Baptist church in Chicago from 1857 to 1886. The present-day University of Chicago, which was established in 1890, is legally a separate institution but the new school eventually recognized Old University alumni as its own. The lone remaining stone from the older school's building, which was destroyed by fire, is preserved on the present school's main quadrangle, where it is set into the wall of the arch between the Classics building and Wieboldt Hall.
