A veteran film editor, Philadelphia-born Otto Lovering (sometimes given as Otho Lovering or Otto Levering) entered films as a production assistant for Vitagraph in 1919. He became an editor in the 1920s, working mainly in outdoor adventures. After the advent of sound, a house editor for Paramount offered him a chance to direct several of the studio's Zane Grey Westerns in 1935. But it was in the editing room Lovering would make his lasting impression, cutting scores of action-dramas that included such classic screen fare as Stagecoach (1939), Foreign Correspondent (1940), and The Man Who Shot Liberty Valance (1962). Lovering enjoyed a long association with director John Ford and also cut the films of Ford's pupil, John Wayne. His death was attributed to a ruptured main artery.
