When an eminent elder colleague requested a scale after the boy had played Lalo's Symphonie espagnole flawlessly, Menuhin wrote in his autobiography, Unfinished Journey, "I groped all over the fingerboard like a blind mouse.... I played the violin without being prepared for violin playing." He began recording early on (playing among other works Elgar
's Violin Concerto at 16, with the composer conducting) and continued to concertize, making a world tour of 73 cities during his 19th year. At the end, however, he felt "tired, indifferent, and sad," and in 1936 began an 18-month sabbatical. Menuhin resumed playing in 1938, but never after with the sublime confidence of his preadolescent years.
During World War II he gave more than 500 concerts for Allied and American troops, but stirred a hornet's nest of controversy as the first major Jewish artist to perform in postwar Germany. Likewise, after the Six Day War in the Middle East, he was vilified for performing charity concerts in Arab countries. Increasingly he devoted himself to the training of young artists, both near London (which became his home in 1952) and at Gstaad, Switzerland. Also in 1952 he went to India, became a disciple of yoga, and a colleague of sitarist Ravi Shankar
. He recorded with Shankar, as he did subsequently with jazz violinist Stéphane Grappelli
. In the middle 1950s Menuhin took up conducting, but was no better schooled than he had been as a child violinist -- and he was conspicuously less successful despite having made a steady stream of recordings begninning in 1958. At age 82 he was guest conducting the Warsaw Symphony on tour when he suffered a fatal heart attack in Berlin.
Menuhin was named Chevalier of the Légion d'honneur in 1948, to the British knighthood in 1965, and to a Lordship in 1993. For his work on behalf of peace worldwide, he was named ambassador of goodwill to UNESCO in 1992. His dedication to the "minds and hearts" of young musicians well may be remembered after his pre-adult celebrity has faded to black. Menuhin married twice, fathered four children, and played frequent recitals with sisters Hephzibah (1920-1981), starting in 1930, and years later with Yaltah (1922-2001), notably at the Bath Festival he founded and directed in the 1960s.
