Alfred Stieglitz (1864–1946) was an influential photographer and gallery-owner, who aimed to raise the status of photography to that of painting. Born to a German immigrant family, he was raised in New York City, and he formed a group of New York City photographers called “Photographic Secession.” With a hand-held camera, he photographed the city, capturing sensitive images of a gritty, urban landscape. Stieglitz also photographed cloudscapes, and said that the ever-changing clouds reflected his emotions. Besides his photographic work, Alfred Stieglitz made a significant contribution to modern art through his “291” gallery (located at 291 Fifth Avenue), which promoted European modernism and supported the careers of many important twentieth-century artists, including Picasso, Matisse, and Georgia O’Keeffe, who he married in 1924.
