He began to play the violin in 1893, and when he was twelve years old showed such remarkable talent that he was sent to Leipsig, where he entered the Leipsig Conservatory, graduating with honors at the age of fifteen. In 1901 he accepted a position as first violinist with the famous Gewandhaus Orchestra under Arthur Nikisch, and two years later he went to Berlin as concertmaster of the Charlottenburg Opera. Here he studied violin with Joachim and composition with Pfitzner. In 1905 he returned to America, and Fritz Scheel, who was then conductor of the orchestra, heard him play and immediately engaged him as concertmaster. At his performances in Philadelphia he has played nearly every modern and classic concerto of value in violin literature. HANS KINDLER, _First Violoncellist—1916-20_
