On completion of his studies, Melendez found his first job at a lumber mill. After watching
Snow White and the Seven Dwarfs, he gained employment at Disney in 1938, where he worked as an assistant animator to
Hawley Pratt whom he befriended and worked together to developed a naval game with toy ships. He worked on what are now considered classics:
Pinocchio,
Fantasia,
Dumbo, and
Bambi and he worked once as an animator for a
Donald Duck short,
The Flying Jalopy. Following the
1941 Disney strike, Melendez was hired by
Leon Schlesinger Productions, later known as
Warner Bros. Cartoons, where he served as animator on the
Looney Tunes and
Merrie Melodies series. He worked in
Bob Clampett's unit, first as an assistant animator for
Rod Scribner, and then as a full animator starting with
Wagon Heels. After Clampett's departure in 1945, the unit was given to
Arthur Davis. When the number of animation units at Warner Bros. was reduced from four to three in 1947, Melendez along with
Emery Hawkins moved to
Robert McKimson's unit for some time. After animating several shorts for McKimson, Melendez was fired by producer
Edward Selzer. Afterwards, he moved over to
United Productions of America (UPA), where he animated on cartoons such as
Gerald McBoing-Boing (1950). Melendez also produced and directed thousands of television commercials, first at UPA, then John Sutherland Productions and Playhouse Pictures. In 1963, Melendez founded his own studio in the basement of his Hollywood home. ,
Bill Melendez Productions is still active and is run by his son
Steven C. Melendez. In addition to animation, Melendez was once a faculty member at the
University of Southern California's Cinema Arts Department. Melendez would also be referenced in the 1961
Looney Tunes short
The Pied Piper of Guadalupe, where his name was used for a music instructor for
Sylvester to learn how to play the flute. At that point, Melendez has been away from Warner Bros. for ten years. ==
