Alfred Stieglitz (American, 1864 - 1946) was a photographer and modern art promoter who was instrumental over his 50-year career in making photography an accepted art form. In addition to his photography, Stieglitz was known for the New York art galleries that he ran in the early part of the 20th century, where he introduced many avant-garde European artists to the U.S. He was married to painter Georgia O'Keeffe.

Camera Work was a quarterly photographic journal published by Alfred Stieglitz from 1903 to 1917. It is known for its many high-quality photogravures by some of the most important photographers in the world and its editorial purpose to establish photography as a fine art. It has been called "consummately intellectual", "by far the most beautiful of all photographic magazines", and "a portrait of an age [in which] the artistic sensibility of the nineteenth century was transformed into the artistic awareness of the present day."
