Photograph by Lewis Wickes Hine (1874-1940), of a 'hostler' refitting a spark arrestor screen in an American steam locomotive. A 'hostler' is someone who services a large vehicle or engine, such as a locomotive. Hine used his photography as a documentary tool to inspire social reform. He photographed New York for about thirty years, concentrating on three main areas; the European immigrants arriving at Ellis Island, the Lower East Side and the Empire State Building.
