Written for juveniles, this biography of Leonard Bernstein, the master musician, conductor, composer, and music educator, provides a resource for students of his life and work. Particular attention is paid to the influences that inspired Bernstein's work, his U.S. education, and his love for teaching. Bernstein's pride in his Jewish heritage is described in discussions of his work with the Israeli Philharmonic and in two of his compositions ("Jeremiah Symphony," and "Kaddish Symphony") which are based on Jewish melodies and prayers and that commemorate the death of John F. Kennedy. A time-line of important life-events is provided. The text concludes with an 8-item bibliography and an index. (MM)
