Harry Callahan (1912-1999) was inspired to take up photography after hearing Ansel Adams speak.
He was largely self-taught, though he did receive encouragement in his pursuits from such luminaries as Edward Steichen and Alfred Stieglitz.
For subject matter, Callahan chose his immediate surroundings, from family, most especially his wife Eleanor Knap, to street scenes, to the landscapes from his escapes to the countryside. In much of his work he experiments with abstraction, each one a poetic reflection on his lived experience.
