William E. Garity (April 2, 1899 – September 16, 1971) was an American inventor and audio engineer who attended the Pratt Institute before going to work for Lee De Forest around 1921.

Garity is best known for his employment at Walt Disney Studios, which used the Cinephone system in the late 1920s and early 30s.

In 1937, also at the Disney Studios, Garity developed the multiplane camera first used to shoot Snow White and the Seven Dwarfs.

Ub Iwerks, having left Disney to work at his own studio, developed an unrelated multiplane camera, during this same time period.

[1][2] In 1940, Garity developed Fantasound, an early stereophonic surround sound system for Disney's Fantasia.
