The father of documentary photography

Lewis W. Hine/George Eastman House Collection

One of the original social justice photographers, Lewis Hine documented the struggles of immigrants, the poor and child laborers in the early 20th century.

A new, two-part exhibition of Hine's work will open at the International Center of Photography in New York on Oct. 4, 2013 and will be on display until Jan. 19, 2014. The show will feature hundreds of photographs from Hine's career, beginning with his portraits of immigrants at Ellis Island in 1905.
