Biography provided by Focal press
 
Hine was a sociologist who took up photography in 1904 in the cause of social reform. He documented immigrants arriving at Ellis Island then followed them in their harsh new lives in the slums of America. In 1907, Hine photographed the Pittsburgh iron and steel workers revealing employment of children under grueling, dangerous conditions. As staff photographer to the National Child Labor Committee from 1911 to 1917, Hine's photographs exposed the negative consequences of a growing consumer society and contributed to the passing of child labor laws. In the 1920s, he embarked on "positive documentation" by making portraits of the working man. His landmark book about the construction of the Empire State Building,Men at Work, was published in 1932.
