University of Chicago alumnus and long-time Hyde Park resident Leon H. Lewis was a great lover of jazz and he spent many an evening in the jazz clubs of the South Side. As part of the Chicago Jazz Club Project, several employees of the Chicago Jazz Archive at the University of Chicago worked with Lewis to create a map of Chicago's jazz clubs from roughly 1915 to the early 1940s. Visitors can view the map in segments, or they can look at the entire map in one fell swoop. For each map, visitors can click on each of the clubs to learn a bit more about the location and view period advertisements and photographs. Additionally, visitors can click on the Club Lists section to view an entire list of all the clubs, complete with brief listing of performers who entertained at each establishment on a regular or semi-regular basis.
