A pencil drawing of a female nude, unframed, the sheet 17" by 13 3/4", signed with the artist's initials in his hand at lower left corner. This subject is likely famed dancer Isadora Duncan, to whom Walkowitz was introduced in Paris around 1920. He executed it is estimated some 5,000 drawings and watercolors of her, as he was fascinated with the fluidity of her movement and never tired of trying to capture it. Walkowitz was born in Siberia to Jewish parents and came to the United States as a child, showing early artistic talent. In the early years of the new century, he found himself at the very center of Modernism in the United States, friends with Arthur Dove, Marsden Hartley, and John Marin among others. Walkowitz became active at Alfred Stieglitz's 291 Gallery, (active there 1911-1917) and participated in the famous 1913 Armory Show in New York. In Paris he was introduced to Isadora Duncan by artist Max Weber, in Rodin's studio no less. Walkowitz is a major American Modernist and his studies of Isadora Duncan, though plentiful, are a landmark tour de force in American art.
