Alfred Stieglitz (January 1, 1864)

Stieglitz was a photographer and promoter of photography as an art form in itself. In 1902 he was one of the founders of Photo-Secession, which stressed craftsmanship in photography. In the famous Gallery 291, along with Edward Steichen, he advanced the careers of other artists and photographers, including very famously Georgia O’Keeffe, who became his second wife. Like many of the early photographers in his group, he was an essentially secular Jew of German descent.
