Bull's days at MGM included 200 of his enduring portraits of such legendary film stars as Clark Gable, Joan Crawford, Katharine Hepburn, Hedy Lamarr, Gary Cooper, Elizabeth Taylor, Vivian Leigh, Spencer Tracy, Ava Gardner, Grace Kelly, and, of course, Greta Garbo.
Winner of four Academy still photography exhibition awards, Clarence Sinclair Bull was born in Sun River, Montana in 1896 and studied with the great Western painter Charles Marion Russell.
His early interest in photography took him to Hollywood in 1918 where he was hired as an assistant cameraman at Metro Pictures. He shot stills of the stars during the production breaks, and when Goldwyn merged with Metro in 1924, he became head of the MGM stills department, and remained at MGM for the rest of his career.
Though Bull was experienced in every branch of his department, from lighting to printing and retouching, he is best-known for his remarkable portraits of Hollywood stars, especially of Greta Garbo. Clarence Sinclair Bull died in 1979.
