Started with Walt Disney in 1929 and moved to Metro-Goldwyn-Mayer in 1938 when they set up their own cartoon unit.
His early style was to incorporate popular and traditional melodies in the manner of a collage, as was common in early animation. However, a discussion with Fred Quimby encouraged him to develop his own style and by the late 1940s, Bradley had a complete set of musical metaphors for all emtions and actions.
Classic works include The Two Mouseketeers (1952) and Cat Concerto (1947), the latter of which uses Liszt's 2nd Hungarian Rhapsody as the basis for the animation and humour.
Bradley retired in 1958 when MGM closed its cartoon department.
