During the first decades of the twentieth century, Stieglitz was the undisputed leader of the idea that a photograph could be art. He made more than three hundred photographs of the painter Georgia O'Keeffe between 1917 and 1937, focusing on various parts of her body--head, breasts, hands, and torso. These intimate pictures express something of O'Keeffe's spirit while reflecting Stieglitz's love for his art and his muse.
