John Winston Ono Lennon, (born John Winston Lennon; 9 October 1940 – 8 December 1980) was an English singer, songwriter, and peace activist who co-founded the Beatles, the most commercially successful band in the history of popular music. He and fellow member Paul McCartney formed a much-celebrated songwriting partnership. Along with George Harrison and Ringo Starr, the group would ascend to world-wide fame during the 1960s.
Born and raised in Liverpool, Lennon became involved in the skiffle craze as a teenager. In 1957, he formed his first band, the Quarrymen, which evolved into the Beatles in 1960. Lennon began to record as a solo artist before the band’s break-up in April 1970. 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 album Double Fantasy. A lone gunman shot and killed Lennon in the archway of his Manhattan apartment building three weeks after the album was released.
