Ray Patterson began his career at Charles Mintz in the late 1920s. (You can view some of Ray's Mintz-era artwork here, courtesy of ASIFA.) In 1940, he went to work at Disney, where he animated on Fantasia, Dumbo and a clutch of shorts.
In 1941, Ray departed Disney after a job action that unionized the studio. He spent the next twenty years working at M-G-M, then another thirty animating and directing television cartoons. He retired as a Hanna-Barbera Vice-President in 1993.
