DuSable Museum of African American History, a Smithsonian affiliate, is in Washington Park at 740 E. 56th Pl. Named for Chicago’s first permanent settler, the museum houses several galleries including Africa Speaks, featuring a collection of masks, carved doors and statues representing various ethnic groups and beliefs. Other galleries recount the history of slavery in America, celebrate the contributions of African-American aviators, and highlight the work of such artists as Augustus Savage and Henry O. Tanner. A Slow Walk to Greatness: The Harold Washington Story highlights the life of the former mayor of Chicago. Traveling exhibits also are presented.
