He studied cello at the New England Conservatory and the Curtis Institute before founding the Juilliard Quartet in 1946 with violinists Robert Koff and Robert Mann, and violist Raphael Hillyer. Winograd left the quartet in 1955 to pursue a conducting career, serving as music director of the Birmingham Symphony in Birmingham, Alabama, and then as music director of the Hartford Symphony Orchestra in Connecticut. After retiring from conducting, he taught chamber music at the Hartt School in West Hartford, Connecticut.
