Pierre Crépô other American photographers influenced by the Abstract Expressionist style of the era included Aaron Siskind, who found formal configurations in graffiti, weathered wood and plaster, and torn billboards (what he called the “detritus of the world”), and Harry Callahan, whose work demonstrated a highly developed sense of linear form. Siskind and Callahan inspired a generation of young photographers through their teachings at the Institute of Design, the school that had been started in 1937 in Chicago by Moholy-Nagy as the New Bauhaus. Barbara Crane, Ken Josephson, and Garry Winogrand were among students who later achieved fame. In England Bill Brandt created expressive photographs of nudes, shooting his subject matter at such close range that the human body took on the appearance of series of patterns and abstract designs. In Germany Otto Steinert led the Fotoform group of photographers, who created close-up views of nature that were also nearly abstract in their effects.
