In 1991, New York–based collector Allan Chasanoff donated to the Museum nearly 1,000 20th-century photographs by Ansel Adams, Richard Avedon, Bill Brandt, Brassaï, Lee Friedlander, Jan Groover, André Kertész, William Klein, Aaron Siskind, Josef Sudek, Garry Winogrand, Joel-Peter Witkin, and many other well- and lesser-known artists. Chasanoff relishes pictures that puzzle him, and he built his collection by questioning what occurs when the camera “captures” the real world but the resulting image creates confusion rather than clarity, challenging photography's reputation as a dependable document.
