Abraham Walkowitz (1878-1965 ) was a Russian born immigrant to the United States who grew up in New York's Lower East Side. He first studied art at the Educational Alliance, the Cooper Union, and the National Academy of Design. He is perhaps best known for his watercolor studies of Isadora Duncan and the dance. However, Walkowitz laid claim to being the first to exhibit truly Modernist paintings in the United States. After 1909, he became a habituee of Alfred Stieglitz's 291 Gallery, and while there became a participant in the debate over Modern Art in America. Walkowitz was an outspoken proponent of continuous experimentation in the arts, which was his definition of Modernism. As an artist, Walkowitz embodied the changing role of the Modernist painter in the United States as Modernism moved from avant-garde protest against established modes to become an accepted style and tradition.
