Gradually businesses began hiring Lewis Hine to take industrial photographs, which were used in advertising. In 1924, his photograph of the railroad engineer won a medal for photography given by the prestigious Art Directors Club of New York. Eight years later, in 1932, Hine published a selection of these photographs in his book, titled Men At Work. But a photo documentary of the construction project proved to be a grueling task. Hine was fifty-six years old, and carrying his camera equipment around the construction of the skyscraper would have taxed the energy of a man half his age. After observing their dangerous work high the city, Hine later wrote, “Some of them are heroes; all of them persons it is a privilege to know.” This was, indeed, the high point of Hine’s photographic efforts to portray the strength and nobility of average people doing very important jobs in their everyday work.
