U.S. Steel created Gary, Indiana. The new steel plant and town built on the site in 1906 were at once a triumph of industrial capitalism and a bold experiment in urban planning. Gary became the canvas onto which the American public projected its hopes and fears about modern, industrial society. In its prime, Gary was known as the magic city, steels greatest achievement, and an industrial utopia ; later it would be called the very model of urban decay. S. Paul OHara traces this stark reversal of fortune and reveals Americas changing expectations. He delivers a riveting account of the boom or bust mentality of American industrialism from the turn of the 20th century to the present day.
