Bernard Herrmann (born Max Herman; June 29, 1911 – December 24, 1975) was an American composer best known for his work in composing for motion pictures. As a conductor, he championed the music of lesser-known composers.

An Academy Award-winner (for The Devil and Daniel Webster, 1941; later renamed All That Money Can Buy), Herrmann is particularly known for his collaborations with director Alfred Hitchcock, most famously Psycho, North by Northwest, The Man Who Knew Too Much, and Vertigo. He also composed scores for many other movies, including Citizen Kane, The Day the Earth Stood Still, The Ghost and Mrs. Muir, Cape Fear, and Taxi Driver. He worked extensively in radio drama (composing for Orson Welles), composed the scores for several fantasy films by Ray Harryhausen, and many TV programs, including Rod Serling's The Twilight Zone and Have Gun–Will Travel.
