When Leonard Bernstein died in 1990 at the age of 72, one of his admirers said he was actually 288 because he led four separate lives: as a conductor, a composer, a pianist and a teacher. No other American musician has ever had such a diverse career. A sickly boy, Bernstein discovered music when he was about 10 and pursued a musical career despite his father's objections. He became literally an overnight sensation when he was 25. With only a few hours notice, he conducted a concert that was broadcast across the entire country. He spent the rest of his life-nearly 50 years-in the spotlight, continually impressing people with his seemingly boundless energy and his love for music. Those qualities have influenced countless numbers of people, adding to their own appreciation of music.
