Miles Dewey Davis III (May 26, 1926 - September 28, 1991) was an American trumpeter, bandleader, composer, and one of the defining figures in the history of jazz. Across a career of nearly five decades, he repeatedly redirected the music, moving from bebop and cool jazz through hard bop, modal jazz, avant-garde experimentation, and jazz fusion. His influence extended beyond jazz into rock, funk, electronic music, hip-hop, and popular culture.
Born in Alton, Illinois, Davis grew up in East St. Louis, where he began trumpet lessons as a teenager. He was already performing locally while still in high school. In 1944, after graduating, he moved to New York City and enrolled at the Juilliard School, although his main purpose was to meet and work with Charlie Parker. Davis soon became part of Parker's influential bebop groups, appearing on recordings made during the mid-1940s. These early sessions placed him close to one of modern jazz's most important breakthroughs, while also revealing a musical personality that favored space, restraint, and tone over the rapid, densely packed lines associated with bebop.
Davis established his own identity with the nonet assembled for a series of recordings in 1949 and 1950. Featuring unusual instrumentation and arrangements by Gil Evans, the group created a softer, more orchestral sound that became associated with cool jazz. The recordings were later collected on *Birth of the Cool*, an album whose importance grew considerably after its 1957 release.
During the 1950s, Davis developed into a major bandleader. His work for Prestige Records, including *Cookin'*, *Relaxin'*, *Workin'*, and *Steamin'*, documented his first great quintet with John Coltrane, Red Garland, Paul Chambers, and Philly Joe Jones. At Columbia Records, he expanded his palette through collaborations with Gil Evans on *Miles Ahead*, *Porgy and Bess*, and *Sketches of Spain*. He also recorded the soundtrack for the French film *Ascenseur pour l'echafaud* in 1957, improvising music that became an influential example of atmospheric film jazz.
In the 1960s, his second great quintet with Wayne Shorter, Herbie Hancock, Ron Carter, and Tony Williams created music marked by rhythmic flexibility, abrupt transitions, and collective interaction. Albums including *E.S.P.*, *Miles Smiles*, *Sorcerer*, *Nefertiti*, and *Filles de Kilimanjaro* charted a path toward more open and electric forms.
That transformation became unmistakable with *In a Silent Way* (1969) and *Bitches Brew* (1970). Combining jazz improvisation with rock instrumentation, studio editing, funk rhythms, and electric keyboards, Davis helped establish jazz fusion. His changing ensembles introduced musicians such as Chick Corea, Joe Zawinul, John McLaughlin, Keith Jarrett, Billy Cobham, and Michael Henderson, many of whom later led important groups of their own.
After a period away from recording in the late 1970s, Davis returned with *The Man with the Horn* and continued working in an electric, commercially aware style through albums such as *Decoy*, *You're Under Arrest*, *Tutu*, and *Amandla*. His final projects included *Doo-Bop*, a posthumously released collaboration with hip-hop producer Easy Mo Bee. Davis died in Santa Monica, California, in 1991. His restless approach to innovation, distinctive trumpet sound, and extraordinary record of artistic reinvention continue to make him one of the central figures of twentieth-century music.
