UNITED STATES - APRIL 09: Photograph by Lewis Wickes Hine (1874-1940), showing riveters at work a quarter of a mile above the pavement during the construction of the Empire State Building, New York. Hine used his photography as a documentary tool to inspire social reform. He photographed New York for about thirty years, concentrating on three separate but related areas: the European immigrants arriving at Ellis Island, the Lower East side and the Empire State Building, for which he was the official photographer.
