Russian painter (mainly of landscapes, portraits, and still-life), graphic artist, and stage designer, born in Moscow. His early work was influenced by Cézanne and he was a founder member of the avant-garde Knave of Diamonds group in 1909. He was also a member of the World of Art group and of AKhRR. From 1918 to 1928 he taught at Vkhutemas, and from 1928 to 1938 he lived in France. After his return to Russia he taught at the Samarkand Regional Art Institute, then in 1944 settled again in Moscow, where he lived for the rest of his life and taught at the Moscow Institute of Applied and Decorative Art. His later works tended towards mild Expressionism. In 1962, four years after his death, they were attacked by Khrushchev, and the press branded him a ‘cultural deviationist’. In 1966, however (two years after Khrushchev's downfall), a comprehensive retrospective exhibition of Falk's work in Moscow rehabilitated him from official censure.
