Gordon Jenkins was a composer, arranger, and conductor who shaped the sound of mid-century American popular music. Born in Webster Groves, Missouri in 1910, he composed standards including "P.S. I Love You," "This Is All I Ask," and "Goodbye," which became Benny Goodman's signature sign-off tune. Jenkins created the narrative song cycle Manhattan Tower (1948), blending songs and narration to evoke New York City romance. As an arranger, he collaborated extensively with Frank Sinatra and Nat King Cole, but his compositional legacy rests on songs that combined sophisticated harmonic language with accessible melodies.
