Aaron Siskind was an American photographer whose work focuses on the details of things, presented as flat surfaces to create a new image independent of the original subject. He was closely involved with, if not a part of, the abstract expressionist movement, and was close friends with painters Mark Rothko, Franz Kline (whose own breakthrough show at the Charles Egan Gallery occurred in the same period as Siskind's one-man shows at the same gallery), and Willem de Kooning.
