While still in his youth, he played well enough to tour Europe as violist of the prestigious Strub Quartet.
After U.S. Army service in World War II he returned to music, teaching, performing, and recording.
[3][4] He was a founding member of The Chamber Music Society of Lincoln Center, and succeeded David Schwartz as violist of the Yale Quartet with Broadus Erle and Syoko Aki (violins) and Aldo Parisot (cello).
[3] His musical interest spanned several centuries, from Baroque to 20th-century works, even inspiring Luciano Berio to write a piece for him.
In addition to performing extensively in Europe and the United States as a soloist and a chamber musician, he also taught many students at Juilliard, the Peabody Conservatory, the New England Conservatory, the Yale School of Music (see this), Boston University, and the Mannes School of Music.
