Sviatoslav Knushevitsky was a Russian cellist from the Soviet period, regarded as the first choice from the Russian cello college and most widely known internationally as an associate from the so-called Oistrakh Trio. In his years as a child, Knushevitsky got cello lessons from his dad, Nikolai Knushevitsky. In 1922, he became students of Semyon Kozolupov on the Moscow Conservatory, where he graduated with honors. Knushevitsky became a member of the All-Union Radio Orchestra in 1928, and in 1929 he joined up with the Bolshoi Theater Orchestra, where he was primary cellist until 1943. During this time period, Knushevitsky also performed chamber music with violinist David Oistrakh and pianist Lev Oborin, developing the informally called Oistrakh Trio in 1940, and he also performed in the Beethoven Quartet with Oistrakh, Pyotr Bondarenko, and Mikhail Terian. He became an trainer on the Moscow Conservatory in 1941, and was a teacher there from 1950 to 1959. Because of his stature, cello concertos had been constructed for him by Nikolai Myaskovsky, Aram Khachaturian, and Reinhold Glière.
