Donald Johnson Ellis (July 25, 1934 – December 17, 1978) was an American jazz trumpeter, drummer, composer, and bandleader. He is best known for his extensive musical experimentation, particularly in the area of time signatures. Later in his life he worked as a film composer, contributing a score to 1971’s The French Connection and 1973’s The Seven-Ups. Ellis was born in Los Angeles, California, on July 25, 1934. His father was a Methodist minister and his mother a church organist. He attended West High School in Minneapolis, MN. After attending a Tommy Dorsey Big Band concert, he first became interested in jazz. Other early inspirations were Louis Armstrong and Dizzy Gillespie. He graduated from Boston University in 1956 with a music composition degree.

Ellis’s last known public performance took place on April 21, 1978, at the Westside Room in Century City. After this, his doctor ordered him to refrain from touring and playing trumpet because it was too stressful on his heart. On December 17, 1978, after seeing a Jon Hendricks concert, Ellis suffered a fatal heart attack at his North Hollywood home where his parents were staying with him. His heart condition is believed to have been cardiac arrhythmia. He was 44. Ellis was buried in the Sheltering Hills section, of Forest Lawn Memorial Park, in Hollywood Hills, California.
