Jascha Heifetz (2 February 1901 – 10 December 1987) was a violinist widely regarded as the greatest violinist of the 20th Century. Heifetz made his first commercial recording on 7 November 1917. Throughout his career, he continued to record, almost always for RCA Victor. He had an immaculate technique and expressive vibrato. From time to time, his near-perfect technique and conservative stage demeanor caused some to accuse him of being overly mechanical, even cold.
