The New York gallery known as 291 first exhibited Georgia O'Keeffe's art in 1916.
The gallery was founded and run by Alfred Stieglitz at 291 Fifth Avenue in Manhattan, which supplied its short name. It had originally been called the Little Galleries of the Photo-Secession, but the address became its best-known identity. The space showed photography alongside avant-garde European and American art.
Anita Pollitzer brought Stieglitz examples of O'Keeffe's charcoal abstractions in 1916. Stieglitz exhibited them at 291 without O'Keeffe's advance permission, and they became her first public presentation in New York. The exhibition helped connect her work with the emerging American modernist movement.
The gallery closed in 1917, but Stieglitz continued promoting O'Keeffe through later galleries, including the Anderson Galleries and An American Place. The Armory Show was a separate 1913 exhibition and was not the venue for O'Keeffe's first New York display, a common historical mix-up.
