Chesney Henry “Chet” Baker Jr. (December 23, 1929 – May 13, 1988) was an American jazz trumpeter and vocalist. He is known for major innovations in cool jazz that led him to be nicknamed the “Prince of Cool”.

Baker earned much attention and critical praise through the 1950s, particularly for albums featuring his vocals: Chet Baker Sings (1954) and It Could Happen to You (1958). Jazz historian Dave Gelly described the promise of Baker’s early career as “James Dean, Sinatra, and Bix, rolled into one”.His well-publicized drug habit also drove his notoriety and fame. Baker was in and out of jail frequently before enjoying a career resurgence in the late 1970s and 1980s.

Baker was born and raised in a musical household in Yale, Oklahoma on 23 December 1929. His father, Chesney Baker Sr., was a professional guitarist, and his mother, Vera Moser, was a pianist who worked in a perfume factory. His maternal grandmother was Norwegian. Baker said that owing to the Great Depression, his father, though talented, had to quit as a musician and take a regular job. In 1940, when Baker was 10, his family relocated to Glendale, California.
