Clarence Kolster (September 6, 1895 – May 6, 1972) was an American film editor, active during the later years of the silent era, right through the 1950s.

[1] His career would include such classics as The Painted Desert, also in 1931, which featured Clark Gable's first speaking role; the 1946 remake of Of Human Bondage; Always Leave Them Laughing, starring Milton Berle and Virginia Mayo; and 1958's Our Miss Brooks starring Eve Arden.

But Kolster's crowning achievement was his first mega-hit, the 1931 version of Frankenstein, starring Boris Karloff.

Kolster's editing of when the monster is revealed has been called, "... possibly the most distinguished piece of cutting in all of horror movie history.

"[2] In addition, the creation sequence, the monster finding the small child by the lake, and the confrontation between the monster and Frankenstein's bride, have all become iconic scenes in film history, often imitated and parodied in later pictures.
