Photographer's credit, title, date of shooting, date of print, handwritten annotations and collector's label on verso. Image: 18.5 x 23.5 cm Sheet: 20.5 x 25.5 cm Trained in sociology at the University of Chicago, Lewis Hine began his collaboration with the National Child Labor Committee (NCLC) in 1908 . He produced a large body of images documenting the working conditions of children, particularly in the cotton factories of the American East Coast. His work bears witness to the political power of photography, its ability to inform, but above all to show in order to raise awareness and convince. These photographs are directly involved in a political awareness that led to the prohibition of child labor at the end of the 1910s. Gabriel Moulin (1872-1945) Redwood trees. California, c. 1898.
