Szymon Goldberg (1 June 1909 – 19 July 1993) was a Polish-born classical violinist and conductor, latterly an American. Born in Włocławek, Congress Poland, Goldberg played the violin as a child growing up in Warsaw. His first teacher was Henryk Czaplinski, a pupil of the great Czech violinist Otakar Ševčík; his second was Mieczysław Michałowicz, a pupil of Leopold Auer. In 1917, at age eight, Goldberg moved to Berlin to study the violin with the legendary pedagogue Carl Flesch. He was also a student of Josef Wolfsthal.
