Which photographer exhibited Georgia O'Keeffe's work at 291 in 1916?

Alfred Stieglitz exhibited Georgia O'Keeffe's work at 291 in 1916.

The works were a group of abstract charcoal drawings that O'Keeffe had made in Virginia. Anita Pollitzer, a friend from the Art Students League, showed them to Stieglitz without O'Keeffe's prior permission. Stieglitz recognized their originality and included them in an exhibition at his gallery.

The event marked a major turning point. O'Keeffe had been teaching art and working outside the center of the New York art world, but the 291 exhibition brought her drawings to influential attention. Stieglitz and O'Keeffe later began a personal relationship and married in 1924.

Stieglitz was not simply a photographer in this story: he also edited journals and promoted modern art. His support helped launch O'Keeffe's public career, while her paintings eventually became independent of his advocacy.
