4479 Charlieparker           Discovered 1985 Feb. 10 by H. Debehogne at the European Southern Observatory.
Charlie "Bird" Parker (1920-1955) was one of the greatest masters of the alto saxophone. Because of his brilliant use of chords and arpeggios, he has usually been named the principal inventor of bebop, which led to the development of modern jazz.
