The photography department represents the most recent curatorial focus at Carnegie Museum of Art. Formally organized in 2008, the collection was acquired gradually over the preceding 50 years and comprises more than 4,500 photographs. Images of Pittsburgh prior to 1960 form the core of the collection, with more than 3,000 photographic prints on this theme by both unknown and celebrated photographers. Internationally acclaimed photographers whose work is in the collection include Julia Margaret Cameron, Elliott Erwitt, Lewis W. Hine, Russell Lee, Barbara Morgan, Alfred Stieglitz, Edward Weston, and many others. Of particular interest is W. Eugene Smith, best known for his Life magazine photo-essays, who is represented by more than 500 works that he made in Pittsburgh in the 1950s. Notable among contemporary photographers is Pittsburgh native Duane Michals, an internationally acclaimed artist who now has more than 200 works in the collection.
