Alfred StieglitzĀ (b. 1864, Hoboken, New Jersey; d. 1946, New York) is credited with elevating photography to the status of art through his tireless efforts as a photographer, collector, curator, writer, and publisher. He founded and edited the journalsĀ Camera NotesĀ andĀ Camera Work, which, along with numerous influential exhibitions at 291, the New York City gallery founded with Edward Steichen in 1905, helped launch the Photo-Secessionist and Pictorialist movements. Stieglitzās own photography focused in-depth on a few subjects, including New York, the cloud studies that he calledĀ Equivalents, and a portrait series of his wife, the painter Georgia OāKeeffe. Aperture has published several limited-edition prints by Stieglitz as well as the collectionsĀ Alfred Stieglitz: A Personal Vision PortfolioĀ andĀ Stieglitz on Photography, which includes a bibliography of his writings.
