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.
The Chicago Poems, and its follow-up volumes of verse, Cornhuskers (1918) and Smoke and Steel (1920) represent Sandburg's attempts to found an American version of social realism, writing expansive verse in praise of American agriculture and industry. All of these tendencies are manifest in Chicago itself.
