Thomas Zehetmair (born 23 November 1961, Salzburg) is an Austrian violinist and conductor. He studied at the Salzburg Mozarteum, where both of his parents taught. His festival debut was at age 16. He was in master classes with Nathan Milstein and Max Rostal. In 1994, Zehetmair formed a string quartet which bears his name. The Zehetmair Quartet performs all works entirely from memory, and learns one new programme a year. Zehetmair has made several recordings for ECM, both as soloist and with his quartet.
