This latest volume in the acclaimed In Focus series examines the life and work of Alfred Stieglitz, concentrating on the Getty Museum's considerable holdings of the work of this American master. In his studies of his wife, Georgia O'Keefe, in his portraits of the urban scene, and in his pictures of natural form, Stieglitz defined the modern movement on photography. In his periodical Camera Work he championed photography as an art form; in his famous gallery "An American Place," he promoted the work of other American modernists. Fifty reproductions with commentaries by Weston Naef, the Getty's curator of photographs, represent both the range of the Getty's collection and the importance of Stieglitz's contribution. The book also includes an edited colloquium on Stieglitz's life and work. Participants included Emmit Gowin, Sarah Greenough, Charles Hagen, John Szarkowski, and Weston Naef.
