John Winston Ono Lennon was born on 9 October 1940. He was an English musician, singer and songwriter who rose to worldwide fame as one of the founder members of The Beatles, one of the most commercially successful and critically acclaimed acts in the history of popular music. Together with Paul McCartney, he formed one of the most celebrated songwriting partnerships of the 20th century.

After his marriage to Yoko Ono in 1969, he changed his name to John Ono Lennon. Lennon disengaged himself from the music business in 1975 to devote time to raising his infant son Sean, but re-emerged with Ono in 1980 with the new album Double Fantasy. He was murdered three weeks after its release.

Lennon revealed a rebellious nature and acerbic wit in his music, writing, drawings, on film, and in interviews. Controversial through his political and peace activism, he moved to New York City in 1971, where his criticism of the Vietnam War resulted in a lengthy attempt by Richard Nixon's administration to deport him, while some of his songs were adopted as anthems by the anti-war movement.

As of 2012 Lennon's solo album sales in the United States exceed 14 million units, and as writer, co-writer or performer, he is responsible for 25 number-one singles on the US Hot 100 chart. In 2002 a BBC poll on the 100 Greatest Britons voted him eighth, and in 2008, Rolling Stone ranked him the fifth-greatest singer of all-time. He was posthumously inducted into the Songwriters Hall of Fame in 1987 and into the Rock and Roll Hall of Fame in 1994.
