Harry Morey Callahan (October 22, 1912 – March 15, 1999) was an American photographer and educator. He taught at both the Institute of Design in Chicago and the Rhode Island School of Design. Callahan's first solo exhibition was at the Art Institute of Chicago in 1951. He had a retrospective at the Museum of Modern Art in New York in 1976/1977. Callahan was a recipient of the Edward MacDowell Medal and the National Medal of Arts. He represented the United States in the Venice Biennale in 1978. Early life Harry Morey Callahan was born in Detroit, Michigan. He worked at Chrysler when he was a young man then left the company to study engineering at Michigan State University. He dropped out, returned to Chrysler and joined its camera club. Callahan began teaching himself photography in 1938. He formed a friendship with Todd Webb who was also to become a photographer. A talk given by Ansel Adams in 1941 inspired him to take his work seriously. In 1941, Callahan and Webb visited Rocky Mountain State Park but didn't return with any photographs.

His technical photographic method was to go out almost every morning, walk through the city he lived in and take numerous pictures. He then spent almost every afternoon making proof prints of that day's best negatives. Yet, for all his photographic activity, Callahan, at his own estimation, produced no more than half a dozen final images a year. He photographed his wife and daughter and the streets, scenes and buildings of cities where he lived, showing a strong sense of line and form, and light and darkness. Even prior to birth, his daughter showed up in photographs of Eleanor's pregnancy. From 1948 to 1953 Eleanor, and sometimes Barbara, were shown out in the landscape as a tiny counterpoint to large expanses of park, skyline or water. He also worked with multiple exposures. Callahan's work was a deeply personal response to his own life. He encouraged his students to turn their
