Bernard Herrmann: Master of the Fantastic, Suspenseful, and Scary
The Devil and Daniel Webster
Jane Eyre
The Ghost and Mrs. Muir
The Day the Earth Stood Still
The 7th Voyage of Sinbad
Journey to the Center of the Earth
The Three Worlds of Gulliver
Mysterious Island
The Bride Wore Black
Jason and the Argonauts
Twisted Nerve
Twilight Zone (the original, dreamy, haunting theme, along with the scores to at least seven individual episodes, including "Where Is Everybody?", "Eye of the Beholder", and "Little Girl Lost")
The Alfred Hitchcock Hour (17 episodes, including "Where the Woodbine Twineth" and "The Jar")
Many Hitchcock film classics, such as:
Vertigo
North By Northwest
Psycho
Note that there is a huge amount of diversity in just this list, from the tender romanticism of The Ghost and Mrs. Muir, to the oriental-flavored lavishness of The 7th Voyage of Sinbad, to the terrifying staccato of Psycho...and that's only the tip of the iceberg. And of course, the above list doesn't include his iconic score for Citizen Kane.
His work for and with Hitchcock alone should grant him a prominent place in the Film Composers' Hall of Fame.
A time for peace - I swear it's not too late! R.I.P., Pete.
