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 artifacts and exhibits about other modern genocides. An early 20th-century German rail car—of the type used by the Nazis during the Holocaust—serves as the Museum's central artifact. Other exhibitions include the Legacy of Absence Gallery, which features contemporary artistic responses to atrocities in Cambodia, Rwanda, Argentina, the Soviet Gulag, and elsewhere. The Make a Difference! Harvey L. Miller Youth Exhibition builds awareness of bullying and tolerance.
