Walter Schumann (October 8, 1913 – August 21, 1958) was an American composer for film, television, and the theater. His notable works include the score for The Night of the Hunter and the Dragnet Theme. (The Dragnet theme was lifted, inadvertently according to Schumann, from Miklós Rózsa's score from the 1946 film The Killers.)
Schumann was born in New York City in 1913. By the early 1930s, he was attending law school at USC when he abruptly quit his studies to perform in a college dance band. Eventually, the members of the band went their separate ways but Schumann continued on within the music industry, working with Eddie Cantor on Cantor's radio show, and recording with Andre Kostelanetz.
Following the outbreak of World War II, Schumann enlisted, eventually becoming the musical director of the Armed Forces Radio Service. He worked with most of the major acts of the war on all the radio shows AFRS produced during this time. After the war, he returned to Los Angeles and worked in the movie and television industry as a composer and arranger, mostly on several Abbott & Costello films. In 1949, Schumann was asked to compose a new theme for a police detective show about to make its debut on the NBC Radio network. He began his theme with a four-note motif—quite possibly the second most famous four-note motif after Beethoven's Fifth Symphony. Dragnet became a smash hit on the radio, and then television and Schumann's theme quickly became instantly recognizable.
