Donald Christopher Barber was an English jazz musician, best known as a bandleader and trombonist. He helped many musicians with their careers and had a UK top twenty trad jazz hit with "Petite Fleur" in 1959. These musicians included the blues singer Ottilie Patterson, who was at one time his wife, and Lonnie Donegan, whose appearances with Barber triggered the skiffle craze of the mid-1950s and who had his first transatlantic hit, "Rock Island Line", while with Barber's band. He provided an audience for Donegan and, later, Alexis Korner, and sponsored African-American blues musicians to visit Britain, making Barber a significant figure in launching the British rhythm and blues and "beat boom" of the 1960s.

Trad jazz, short for "traditional jazz", is a form of jazz in the United States and Britain that flourished from the 1930s to 1960s, based on the earlier New Orleans Dixieland jazz style. Prominent trad jazz musicians such as Chris Barber, Freddy Randall, Acker Bilk, Kenny Ball, Ken Colyer and Monty Sunshine performed a populist repertoire which also included jazz versions of pop songs and nursery rhymes.
