The 291 Gallery is an art gallery located in New York City, known for its role in promoting modern art in the early 20th century. Founded by photographer and art dealer Alfred Stieglitz in 1905, it showcased works by influential artists such as Georgia O'Keeffe and Pablo Picasso. The gallery played a significant part in introducing European avant-garde art to American audiences. The name "291" comes from the gallery's original address at 291 Fifth Avenue. It became a hub for artists and intellectuals, fostering discussions about art and culture. The gallery closed in 1917, but its impact on the art world continues to be recognized today.
