John W. Dunn was a Scottish screenwriter and animator for animated cartoons of Disney, Warner Bros., and DePatie-Freleng Enterprises, from 1955 until his death in 1983. Dunn began his career at the Walt Disney cartoon studio, where his first story credit was Man in Space, which received an Oscar nomination. He was also an animator for Toby Tortoise Returns.
Outside of Disney, Dunn is known for animating and later writing many cartoons for Warner Bros. Cartoons. He began with The Pied Piper of Guadalupe, which was also nominated for an Oscar. He usually worked under Friz Freleng and Chuck Jones' units. After the Warner's cartoon studio closed in 1963, Dunn joined DePatie–Freleng Enterprises; in 1964, he crafted the story for The Pink Phink, which earned the Oscar as Best Animated Short. He continued to work on more Pink Panther shorts the next two decades, as well as other shows, like the 1967 Spider-Man cartoon series, various Looney Toons cartoons, and The Ri¢hie Ri¢h/Scooby-Doo Show.
Dunn died in San Fernando, California of heart failure on January 17, 1983.
