At age 14, he was sponsored by composer Arthur Benjamin to attend the Royal College of Music in London in 1937–39. In his final year, he played with Benjamin a piece the composer wrote for Munroe. His apprenticeship continued in Philadelphia at the Curtis Institute of Music, where he was a student of cellist Gregor Piatigorsky.
After serving during World War II, he completed his apprenticeship at the Curtis. In 1949, he won the Naumburg award and made his recital debut in New York in November of that year.
