Henryk Szeryng
He gave his first solo performance on 6 January 1933 playing the Brahms Violin Concerto with the Warsaw Philharmonic Orchestra. Szeryng spoke seven languages fluently, so when World War II broke out he became an official interpreter for the Polish government which was based in exile in London. He went with the prime minister to Mexico to find a home for refugees. During the war he gave more than 300 concerts for Allied troops all over the world. During one of these concerts in Mexico City he was given the job of being head of the string department of the university there.
