Why did he take this picture? In 1951 he told his friend Walter Rosenblum that “he was trying to photograph the rushing to work … physical movement expressed by the abstract spotting of people and shapes.” By stepping back, Strand surveys the ceaseless bustle of the business class, never stopping to enjoy the present, caught in the commercial flow of metropolitan life. City Hall Park, as a transit hub, becomes a non-park, no longer doing what Progressive Era urban planners such as Jacob Riis intended parks to do.
