Alfred Stieglitz (1864-1946) was a key figure in America's acceptance of photography as a serious form of artistic expression. His work bridges the gap between the self-consciously aesthetic Pictorialist photography at the turn of the century, and the more precisely descriptive 'straight' photography of the 1920s and 1930s. This monograph covers Stieglitz's career and provides the perfect introduction to the work of a major force in the American modernist movement.
