291

291 is shorthand for Alfred Stieglitz's The Little Galleries of the Photo-Secession at 291 Fifth Avenue in NYC and came to refer to a group of avant-garde artists and writers who showed there or were a part of the Stieglitz circle. These artists (Florine Stettheimer, Georgia O'Keeffe, Arthur Dove, Charles Demuth, Marsden Hartley, and others) built on European developments creating some of the earliest works in the United States to explore abstraction.
