[1] Ferguson, known at the studio as "Norm" or "Fergy", was the primary animator of the witch from Snow White and the Seven Dwarfs, the first in a long line of great Disney feature villains.

He is remembered for having worked "rough" and "loose", in animation terms, with a focus on feeling, action, and the character's personality rather than detail, structure, or formal draftsmanship.

Animator Shamus Culhane remembered Ferguson as having produced a high volume of work- about 18 feet a week as opposed to the more average ten at the Disney Studios at the time.

Norm Ferguson served as a sequence director or directing animator on many of the classic Walt Disney features films from Snow White and the Seven Dwarfs in 1937 through the 1950s, including Pinocchio, Fantasia, Bambi, Cinderella, Peter Pan, and Alice in Wonderland.

The two men are the subjects of chapter five in Thomas and Johnston's Disney Animation: The Illusion of Life, titled "Cartoon Comes of Age: Norm Ferguson and Ham Luske."
