Roy David Eldridge (January 30, 1911 - February 26, 1989), nicknamed "Little Jazz" was an American jazz trumpet player. His sophisticated use of harmony, including the use of tritone substitutions, his virtuosic solos and his strong influence on Dizzy Gillespie mark him as one of the most exciting musicians of the Swing Era and a precursor of bebop.
