Alfred Stieglitz's gallery 291 first exhibited Georgia O'Keeffe's drawings in 1916.
The gallery known as 291 was founded by Alfred Stieglitz and operated at 291 Fifth Avenue in New York. Its formal name was the Little Galleries of the Photo-Secession, but it became widely identified by its street number. In 1916, Stieglitz displayed a group of O'Keeffe's abstract charcoal drawings there.
The exhibition introduced her work to an influential New York audience. O'Keeffe was not present at the opening and had not initially sought Stieglitz's personal intervention. The drawings had been sent to New York by Anita Pollitzer, who showed them to Stieglitz without O'Keeffe's prior permission.
291 had already exhibited European modernists and American innovators, including Pablo Picasso, Henri Matisse, and Paul Cézanne. The gallery closed in 1917, but its role in O'Keeffe's emergence remained important.
