Which artist founded the New York gallery 291, where Georgia O'Keeffe first exhibited in 1916?

Alfred Stieglitz founded the New York gallery 291, where Georgia O'Keeffe first exhibited in 1916.

The gallery was originally called the Little Galleries of the Photo-Secession and took its familiar name from its address at 291 Fifth Avenue. Stieglitz used the space to show photography and avant-garde European and American art, including works by artists who were not widely accepted by conservative institutions.

O’Keeffe’s charcoal abstractions were displayed there in 1916 after Stieglitz saw them through an intermediary. The exhibition marked her first public presentation in New York and helped establish the connection between her work and Stieglitz’s artistic circle.

The gallery later showed major modern artists including Pablo Picasso, Henri Matisse, and Constantin Brâncuși. Its importance was therefore broader than O’Keeffe’s career: it helped introduce modern European ideas and experimental American art to New York audiences.
