Edward Kennedy "Duke" Ellington (April 29, 1899 – May 24, 1974) was an American composer, pianist, and leader of a jazz orchestra, which he led from 1923 until his death over a career spanning more than six decades.

Personal life Ellington married his high school sweetheart, Edna Thompson (d. 1967), on July 2, 1918, when he was 19. The next spring, on March 11, 1919, Edna gave birth to their only son, Mercer Kennedy Ellington.

Ellington was joined in New York City by his wife and son in the late twenties, but the couple soon permanently separated. According to her obituary in Jet magazine, she was "homesick for Washington" and returned. In 1929, Ellington became the companion of Mildred Dixon, who traveled with him, managed Tempo Music, inspired songs at the peak of his career, and raised his son.

In 1938 he left his family (his son was 19) and moved in with Beatrice "Evie" Ellis, a Cotton Club employee. Their relationship, though stormy, continued after Ellington met and formed a relationship with Fernanda de Castro Monte in the early 1960's. Ellington supported both women for the rest of his life.

Ellington's sister Ruth (1915–2004) later ran Tempo Music, his music publishing company. Ruth's second husband was the bass-baritone McHenry Boatwright, whom she met when he sang at her brother's funeral. As an adult, son Mercer Ellington (d. 1996) played trumpet and piano, led his own band, and worked as his father's business manager.

Ellington was a member of Alpha Phi Alpha and was a freemason associated with Prince Hall Freemasonry.

Death Ellington died on May 24, 1974, of complications from lung cancer and pneumonia, a few weeks after his 75th birthday. At his funeral, attended by over 12,000 people at the Cathedral of St. John the Divine, Ella Fitzgerald summed up the occasion: "It's a very sad day. A genius has passed."

He was interred in the Woodlawn Cemetery, the Bronx, New York City.
