Will H. Schaefer, Composer.
Go ahead, hum a classic TV theme song, chances are Will Schaefer had something to do with it. The man behind such catchy tunes as the themes from "I Dream of Jeannie", "Hogan's Heroes" and "The Flintstones" has passed away from cancer.
Schaefer, as well as composing background music for many shows, is also responsible for orchestrating the "It's A Small World" song in the ride of the same name in the Disney theme parks.
He was 78.
