Terrytoons was a studio in New Rochelle, New York that produced animated cartoons for theatrical release from 1917 - 1971. Terrytoons was founded by Paul Terry and operated out of the "K" Building in downtown New Rochelle. The studio created many cartoon characters including Heckle and Jeckle, Mighty Mouse, Gandy Goose, Sourpuss, Dinky Duck and Luno. The "New Terrytoons" period of the late 1950s through early 1970s produced such characters as Hector Heathcote, Hashimoto and Deputy Dawg as well as The Mighty Heroes. Ralph Bakshi got his start as an animator, and eventually as a director, at Terrytoons. Terrytoons were originally released to theaters by 20th Century Fox. The Terrytoons library was later purchased by the CBS Corporation.
