Born Harold Frazer. He came to the U.S. as part of a touring Australian light opera company, then in 1915 he joined Hal Roach; for the next four years he appeared as comic support to Harold Lloyd in dozens of one-reel comedies. In 1919 he was given his own one-reel comedy series, directed by Charles Parrott; known for his drooping mustache, frenetic manner, roly-poly eyes, and small frame, he tended to play henpecked husbands and other weak characters. By 1922 he was extremely popular and starring in two-reelers. He left Roach in 1926 and started his own company, but his popularity waned and he quit making films for several years. He returned to the screen in the early '30s, playing small roles in feature films; often, several years went by between his film roles, but he was still onscreen as late as 1961. He was the brother of actress Daphne Pollard.
