Georgia O'Keeffe had her first solo exhibition at the New York gallery known as 291.
The gallery was founded and directed by photographer Alfred Stieglitz. Its formal address was 291 Fifth Avenue, and the number became its familiar name. Stieglitz showed O'Keeffe's abstract charcoal drawings there in 1916, helping introduce her work to New York's modern-art audience.
The exhibition marked a major early step in O'Keeffe's professional career. Her drawings attracted attention because they used simplified lines and forms rather than following the academic realism dominant in much American art at the time.
291 also exhibited European modernists, including Pablo Picasso, Henri Matisse, and Paul Cézanne, alongside American artists. Although O'Keeffe later became closely associated with Stieglitz, her work eventually developed beyond the gallery's influence and established her as a major independent American artist.
