The New York gallery that showed Georgia O’Keeffe’s work in 1916 was 291. The gallery was founded and directed by photographer Alfred Stieglitz and took its name from its address at 291 Fifth Avenue.
Stieglitz used 291 to present modern European and American art, including photography, painting, sculpture, and works by artists who were not yet widely accepted in the United States. O’Keeffe’s charcoal abstractions appeared there in 1916 after Anita Pollitzer showed them to Stieglitz.
The gallery closed in 1917, but its influence continued through Stieglitz’s later spaces, including the Intimate Gallery and An American Place. The number 291 is therefore both a street address and a landmark name in the history of American modernism.
