Why the Colored American Not in the World’s Columbian Exposition, an interactive exhibition, examining black Americans’ contributions to the World’s Columbian Exposition of 1893, will open through Oct. 11. The exhibition, inspired by the same-titled pamphlet co-authored by famed civil rights activist Ida B. Wells, highlights the historical accounts of black Americans’ thoughts, feelings and experiences related to the Chicago’s World’s Fair. In addition, it draws on the 120th anniversary of the exposition to explore how blacks felt about their exclusion from the planning processes, some of the lesser-known contributions of black Chicagoans during that period, and issues concerning ethnic representation within the fair’s exhibits.
