The Pullman neighborhood exemplifies the "company town" style of industrial development, and was the site of one of the most famous labor clashes in U.S. history. George M. Pullman began construction in 1880, seeking to create a harmonious environment that would prevent class tensions. However, Pullman's social control experiment alienated workers, and conditions worsened when Pullman maintained the cost of rents but decreased wages during the 1893 financial panic. The resulting 1894 battle between the American Railway Union (ARU), an early industry-wide union led by Eugene V. Debs, and the General Managers' Association (GMA), a powerful combination of railroad owners, ended when President Grover Cleveland called in federal troops over the objections of Mayor John P. Hopkins and Governor John Peter Altgeld. In 1960, the city of Chicago declared the area "blighted" and moved to replace it with a new industrial park. The residents saved Pullman's main housing and it continues to be a vibrant community. For more information on Pullman, visit the museum at 112th and Forrestville.
