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 Miklos Rozsa'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.

He wrote one opera, John Brown's Body, which premiered in Los Angeles in 1953 and subsequently ran for sixty-five performances on Broadway at the New Century Theatre. Around this time, Schumann gathered together 20 talented vocalists and The Voices Of Walter Schumann was born. The ensemble recorded several easy-listening albums, similar to those recorded by Jackie Gleason, for both Capitol Records and RCA Victor. By 1955, Schumann was busy composing and conducting the score to the classic Robert Mitchum film The Night of the Hunter and won an Emmy for his wildly popular "Dragnet" theme. He recorded a space-age themed, spoken-word album titled "Exploring the Unknown," and his "Voices" troupe recorded a popular, 19-track Christmas album, "The Voices of Christmas".

In 1956 and 1957 Schumann continued to record with the Voices and they appeared on the first season of NBC's The Ford Show, Starring Tennessee Ernie Ford Show. However, by the summer of 1958, poor health prompted Schumann to be admitted to the Mayo Clinic, where he underwent one of the first open heart surgeries in the United States. Complications arose following the operation, and Schumann died on August 21, 1958, aged 44, just weeks before the third season of The Tennessee Ernie Ford Show was scheduled to begin. Members of Schumann's "Voices" ensemble were stunned by his sudden death, but decided to continue performing. They were renamed "The Top Twenty," and they carried on with Ford for another five years.
