(August 2, 1894 in San Francisco – May 10, 1974 in Santa Monica, California) was a famed movie cinematographer who won an Oscar for his work on the 1935 film A Midsummer Night's Dream.

From a young age, Hal Mohr wanted to pursue a career in cinematography because he was curious to learn about how to make pictures move onscreen.

Although Mohr mainly worked as a cinema portraitist on movies such as The Wedding March, A Midsummer Night's Dream, and the Technicolor The Phantom of the Opera, he was passionate about exploring the limits of the camera.

He was inspired by the moving shots in the Italian movie, Cabiria, and developed a camera with special tracking abilities for his 1914 film, Pan's Mountain.

Mohr was nominated for an Academy Award for Best Cinematographer for his work on The Four Poster (1952), a film based on a play of the same name, written by Jan de Hartog.

Other film cinematographer credits include Little Annie Rooney (1925), The Big Gamble (1931), Cheers for Miss Bishop (1941), Another Part of the Forest (1948) and The Wild One (1953).
