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. Even so, most critics agree he infused his playing with feeling and reverence for the wishes of the composers.
