American composer Gunther Schuller was famous for pioneering "Third Stream," an approach that combines jazz with advanced classical forms. A superb French horn player, Schuller premiered his own French Horn Concerto in Cincinnati at age 19; in the 1950s, Schuller worked with Miles Davis and John Lewis and pursued his interest in "Third Stream." Best-known for his Seven Studies on Themes of Paul Klee (1959), Schuller served several years as president of New England Conservatory, authored several key books on jazz history, and won Grammys for his ragtime recordings and the Pulitzer Prize for Of Reminiscences and Reflections (1993).
