In the 1970s a group of neo-Nazis planned a march in the predominantly Jewish suburb of Skokie, and local Holocaust survivors reacted by creating the Holocaust Memorial Foundation of Illinois, a group determined to educate the public about the atrocities of World War II. It took years of planning, but in 2009 the foundation finally unveiled a gem of a museum. The 65,000-square-foot building, designed by architect Stanley Tigerman, houses more than 11,000 Holocaust-related objects. An early 20th-century German railcar—of the type used by the Nazis during the Holocaust—serves as the central artifact. Permanent exhibits include the Legacy of Absence Gallery, which evokes other contemporary genocides and atrocities through art, and the Harvey L. Miller Family Youth Exhibition, which aims to teach kids about respecting differences.
