John Ono Lennon, MBE (born John Winston Lennon; 9 October 1940 – 8 December 1980) was an English singer, songwriter, musician, and activist who co-founded The Beatles. He and fellow member Paul McCartney formed a much-celebrated songwriting partnership.
Born and raised in Liverpool, Lennon became involved in the skiffle craze as a teenager. He formed his first band, the Quarrymen, in 1957 which evolved into the Beatles in 1960. When the group disbanded in 1970, Lennon embarked on a sporadic solo career that produced albums including John Lennon/Plastic Ono Band and Imagine, and songs such as "Give Peace a Chance", "Working Class Hero", and "Imagine". After he married Yoko Ono in 1969, he added "Ono" as one of his middle names. Lennon disengaged himself from the music business in 1975 to raise his infant son Sean, but re-emerged with Ono in 1980 with the new album Double Fantasy. He was shot and killed in front of his Manhattan apartment 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 from London to Manhattan in 1971, where his criticism of the Vietnam War resulted in a lengthy attempt by the Nixon administration to deport him. Some of his songs were adopted as anthems by the anti-war movement and the larger counterculture.
