Pete Briggs (born 1904, date of death unknown) was an
American jazz bass and tuba player.
Briggs was born in Charleston,
South Carolina and was related to
bandleader Arthur Briggs. He first played professionally in the early 1920s
with the Jim Jam Jazzers, and soon after played with the Lucky Boy Minstrels.
In 1926 he moved to Chicago,
playing with Carroll Dickerson, Jimmie Noone, and Louis Armstrong, with whom he
recorded copiously. Briggs appears on many of the Hot Seven recordings made
with Armstrong and his band.
