The collection note P&P's curator says:
Working as an investigative photographer for the National Child Labor Committee (NCLC), Lewis Hine (1874-1940) documented working and living conditions of children in the United States between 1908 and 1924. The NCLC photos are useful for the study of labor, reform movements, children, working class families, education, public health, urban and rural housing conditions, industrial and agricultural sites, and other aspects of urban and rural life in America in the early twentieth century.
The collection consists of more than 5,100 photographic prints and 355 glass negatives, given to the Library of Congress, along with the NCLC records, in 1954 by Mrs. Gertrude Folks Zimand, acting for the NCLC in her capacity as chief executive.
