Alfred Stieglitz (1864–1946) spent much of his career establishing a dialogue between advanced photography, painting, and sculpture, and his more than three hundred photographs of the painter Georgia O'Keeffe (1887–1986) count as a signal contribution to this long-term enterprise. Two years after opening an exhibition space, the Little Galleries of the Photo-Secession (Gallery "291"), in 1905, Stieglitz began showing modern art there as well. Drawings, paintings, and sculpture by Auguste Rodin, Henri Matisse, Pablo Picasso, and Constantin Brancusi, among others, influenced Stieglitz in his thinking about photography.
