Charles Mingus Jr. (April 22, 1922 – January 5, 1979) was an American jazz double bassist, pianist, composer, and bandleader. A major proponent of collective improvisation, he is considered to be one of the greatest jazz musicians and composers in history,^[1] with a career spanning three decades and collaborations with other jazz musicians such as Louis Armstrong, Duke Ellington, Charlie Parker, Dizzy Gillespie, and Herbie Hancock.

Mingus’s compositions continue to be played by contemporary musicians ranging from the repertory bands Mingus Big Band, Mingus Dynasty, and Mingus Orchestra, to the high school students who play the charts and compete in the Charles Mingus High School Competition. In 1993, the Library of Congress acquired Mingus’s collected papers—including scores, sound recordings, correspondence and photos—in what they described as “the most important acquisition of a manuscript collection relating to jazz in the Library’s history”.

Charles Mingus was born in Nogales, Arizona. His father, Charles Mingus Sr., was a sergeant in the U.S. Army. Mingus Junior was largely raised in the Watts area of Los Angeles. His maternal grandfather was a Chinese British subject from Hong Kong, and his maternal grandmother was an African-American from the southern United States. Mingus was the great-great-great-grandson of the family’s founding patriarch who was, by most accounts, a German immigrant. His ancestry included German American, African American, and Native American.
