The musical Chicago is based on a play of the same name by reporter and playwright Maurine Dallas Watkins, who was assigned to cover the 1924 trials of accused murderers Beulah Annan and Belva Gaertner for the Chicago Tribune.
Chicago is known by a plethora of nicknames, including âThe Windy Cityâ, âChi-Townâ, the âSecond Cityâ, âChicagolandâ, and in a play on New Yorkâs nickname, âThe Big Onion.â In a poem by Carl Sandberg which was published in 1916 titled âChicago,â he refers to the city as âCity of the Big Shoulders.â
