Book excerpt: Created by the federal government in 1933 to revitalize a region twice the size of New England, the Tennessee Valley Authority began as an experiment of unprecedented proportions. Seen here through picture postcards, the dramatic achievements of the TVA take on a personal aspect, as individuals visit the hydroelectric projects and enjoy the newly created recreational opportunities. Tangible benefits are also documented, such as improved navigation, new roads and bridges, and abundant and inexpensive electricity. Influenced by such visionaries as Gifford Pinchot, Theodore Roosevelt, and George Norris, the agency also dealt with regional issues, including river commerce, soil conservation, and flood control.
