Gordon Hill Jenkins (May 12, 1910 – May 1, 1984) was an American composer, arranger, conductor, and musician who played a significant role in popular music during the 1940s and 1950s. Born in Webster Groves, Missouri, Jenkins began his career writing arrangements for a radio station in St. Louis and was later hired by Isham Jones to work with his dance band. After the band disbanded in 1936, Jenkins became a freelance arranger, contributing to projects by notable musicians such as Paul Whiteman and Benny Goodman.

In 1938, Jenkins moved to Hollywood, where he worked for Paramount Pictures and NBC. He became Dick Haymes' arranger and, in 1945, joined Decca Records as a staff conductor, eventually becoming the musical director. Jenkins was responsible for bringing The Weavers to Decca and worked with a host of legendary artists, including Frank Sinatra, Nat King Cole, Louis Armstrong, Judy Garland, and Ella Fitzgerald. His lush string arrangements became his signature style.

Jenkins achieved success with his own recordings, such as the musical vignettes "Manhattan Tower" and "California." He also arranged and conducted acclaimed albums for Nat King Cole and Frank Sinatra, including Sinatra's "Where Are You?" and "No One Cares." Jenkins' work on Sinatra's "September Of My Years" won him a GRAMMY for his arrangement of "It Was a Very Good Year."

In addition to his recording success, Jenkins performed at prestigious venues like New York's Capitol Theater and the Hollywood Bowl. He was inducted into the Songwriters Hall of Fame in 1982, recognizing his enduring impact on music. Jenkins passed away in Malibu, California, in 1984, leaving behind a legacy of influential music and collaborations.
