Vladimir Sofronitsky
Sofronitsky gave his first solo concert in 1919, and went on his foreign tour in France in 1928. In 1945, he was sent by Joseph Stalin to play at the Potsdam Conference. That was his only time performing outside the Soviet Union. Sofronitsky was teaching at the Leningrad Conservatory from 1936 to 1942, and then at the Moscow Conservatory until his death in 1961.
