Oscar Shumsky (March 23, 1917 in Philadelphia – July 24, 2000 in Rye, New York) was an American violinist and conductor born to Russian-Jewish parents.
Oscar Shumsky started learning the violin at the age of three, and made his concert debut at the age of seven with the Philadelphia Orchestra under Leopold Stokowski, who declared him to be "the most astounding genius I have ever heard". Fritz Kreisler took a special interest in him, and he played Kreisler's own cadenzas to the Beethoven violin concerto to him after learning them by ear. He was a pupil of Leopold Auer from 1925 and studied at the Curtis Institute of Music from 1928 to 1936, continuing his studies with Efrem Zimbalist after Auer's death in 1930. His New York debut was in 1934 and his Vienna debut was in 1936. He played first violin in the Primrose Quartet from 1939, and the same year joined the NBC Symphony Orchestra under Arturo Toscanini. During the Second World War, he served in the U.S. Navy.
His violin was a Stradivari of 1715 known as 'Ex-Pierre Rode' or the 'Duke of Cambridge'. The violin has been previously owned by Pierre Rode at one point. It has been used by Shumsky to recorded the complete 24 Caprices by Rode. He tells how he came to acquire the instrument:
