Carl Sandburg called it the City of Big Shoulders. Carolyn Martineau dubbed it the place that invented the wind-chill. Consider what Chicago means to you in Chicago Authored, the first-ever entirely crowd-sourced museum exhibition, which opens at the Chicago History Museum on Saturday, October 17, 2015. We asked Chicago to give us an assignment, and we are thrilled to present Chicago Authored, an exhibition that epitomizes the Museums mission to share Chicagos stories, said Chicago History Museum President Gary T. Johnson . The Museum boldly asked Chicagoans to select an exhibition topic, entirely free of suggestion, in a tournament-style competition dubbed the Chicago History Bowl. The submissions that flooded in included Chicagos neighborhoods, Prohibition, architecture, the Great Chicago Fire, and notable women of Chicago.
