John Arnold (1889-1964) had been photographing films at Metro since 1916 when he was assigned to The Broadway Melody. He followed this up with The Hollywood Revue of 1929, and was soon after kicked upstairs to become head of the studio’s Camera Department.
Arnold was a co-founder and governor of the American Society of Cinematographers, with a particular interest in technical innovation. This bore dividends on The Broadway Melody when he was able to devise the “coffin on wheels,” a soundproof but mobile camera booth that enabled the film to transcend the existing limitations of sound cinema.
Later in his career Arnold won Oscars for two of his inventions: in 1938, for a semi-automatic follow focus device; and in 1940 for a mobile camera crane.
Arnold was also important to the campaign that secured the inclusion of cinematographers in Hollywood credits.
