Altgeld Hall, located at 1409 West Green Street in Urbana, Illinois on the University of Illinois at Urbana-Champaign (UIUC) campus, was built in 1896-97 and was designed by Nathan Ricker and James McLaren White of the University's architecture department in the Richardsonian Romanesque style. The building was originally the University Library, and received major additions in 1914, 1919, 1926, and 1956. From 1927-55 it was used by the College of Law, and from 1955 on by the Department of Mathematics and the Mathematics Library. The University Chime in the bell tower – which marks the hours, half hours, and quarter hours and plays a ten minute concert every school day from 12:50 - 1:00 PM – was installed in 1920. The building was officially named "Altgeld Hall" in 1941.
