Mr. Winograd was the original cellist of the Juilliard String Quartet, which was established in 1946; the other founding members included current Juilliard faculty member Robert Mann, who served as first violinist; the late violinist Robert L. Koff; and violist Raphael Hillyer. One of the first quartets-in-residence at an American music conservatory, the ensemble forged a reputation as a champion of contemporary music, and during Mr. Winograd’s tenure, it made many acclaimed recordings, including the early 1950s recordings of the Six Bartok String Quartets for Columbia Records (now Sony Classical).

Born in New York City on April 22, 1920, Mr. Winograd studied cello with Jean Bedetti at the New England Conservatory and with Felix Salmond at the Curtis Institute. He was a cellist with the NBC Symphony Orchestra, performing under Arturo Toscanini and Leopold Stokowski.

As a member of the J.S.Q., Mr. Winograd served on the Juilliard faculty from 1946-55. He left the quartet in 1956 to pursue a conducting career, which began when he conducted for MGM records. From 1960-64, he served as music director of the Birmingham (Ala.) Symphony, and from 1964-85, as music director of the Hartford Symphony Orchestra. He made several appearances at Juilliard as a guest conductor. Following his retirement from the Hartford Symphony, Mr. Winograd taught chamber music at the Hartt School in West Hartford, until he moved to Lincoln Park, N.J., to be nearer to his family.

Mr. Winograd met his wife of 37 years, Betty, a pianist, at Juilliard. She died of breast cancer in 1987. He is survived by his son Nicholas and daughter-in-law Barbara Garrison, of Pennsylvania; daughter Wendy and son-in-law Ward Dill, of New Jersey; son Peter and daughter-in-law Caterina Szepes, of New York; and seven grandchildren.
