Shamus Culhane

James "Shamus" Culhane (November 12, 1908 — February 2, 1996) was an American animator, film director, and film producer.

While at the Disney studio, he discovered while working on Hawaiian Holiday's crab sequence an animation method that involved stewing for multiple days, before drawing the entire thing in rough sketches all at once, straight ahead, without invoking the left side of the brain. He was a lead animator on Snow White and the Seven Dwarfs, animating arguably the most well-known sequence in the film, the animation of the dwarves marching home singing "Heigh-Ho". The scene took Culhane and his assistants six months to complete. During this time he developed his 'High-speed' technique of using only the right side of the brain and animating with quick dashed-off sketches.

At his death on February 2, 1996, Culhane was survived by second wife, the former Juana Hegarty, and by two sons from his first marriage to Maxine Marx (the daughter of Chico Marx) which ended in divorce: Brian Culhane of Seattle and Kevin Marx Culhane of Portland, Ore.
