In 1907, Hine became the staff photographer of the
Russell Sage Foundation; he photographed life in the steel-making districts and people of
Pittsburgh, Pennsylvania, for the influential sociological study called
The Pittsburgh Survey. shucker in Alabama Canning Co. (
Bayou La Batre, Alabama, 1911) In 1908, Hine left his teaching position to become the photographer for the
National Child Labor Committee (NCLC). Over the next decade, Hine documented child labor, with a focus on the use of child labor in the
Carolina Piedmont, to aid the NCLC's lobbying efforts to end the practice. In 1913, he documented child laborers among cotton mill workers with a series of
Francis Galton's
composite portraits. Hine's work for the NCLC was often dangerous. As a photographer, he was frequently threatened with violence or even death by factory police and foremen. At the time, the immorality of child labor was meant to be hidden from the public. Photography was not only prohibited but also posed a serious threat to the industry. To gain entry to the mills, mines and factories, Hine was forced to assume many guises. At times he was a fire inspector,
postcard vendor, bible salesman, or even an industrial photographer making a record of factory machinery. During and after
World War I, he photographed
American Red Cross relief work in Europe. In the 1920s and early 1930s, Hine made a series of "work portraits", which emphasized the human contribution to modern industry. In 1930, Hine was commissioned to document the construction of the
Empire State Building. He photographed the workers in precarious positions while they secured the steel framework of the structure, taking many of the same risks that the workers endured. To obtain the best vantage points, Hine was swung out in a specially designed basket 1,000 ft above Fifth Avenue. At times, he remembered, he hung above the city with nothing below but "a sheer drop of nearly a quarter-mile." During the Great Depression, Hine, once again, worked for the Red Cross, photographing drought relief in the American South, and for the
Tennessee Valley Authority (TVA), documenting life in the mountains of eastern Tennessee. ==Later life==
