John Winston Lennon, MBE (9 October 1940 – 8 December 1980) was an English musician and singer-songwriter who rose to worldwide fame as one of the founding members of The Beatles, one of the most commercially successful and critically acclaimed acts in the history of popular music. Along with fellow Beatle Paul McCartney, he formed one of the most successful songwriting partnerships of the 20th century.

Born and raised in Liverpool, Lennon became involved in the skiffle craze as a teenager, forming his first band, The Quarrymen evolving into The Beatles in 1960. As the group disintegrated towards the end of the decade, Lennon embarked on a solo career that produced the critically acclaimed albums John Lennon/Plastic Ono Band and Imagine, and iconic songs such as "Give Peace a Chance" and "Imagine". 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 his infant son Sean, but re-emerged in 1980 with a new album, Double Fantasy. He was murdered three weeks after its release.

Lennon revealed a rebellious nature and acerbic wit in his music, his writing, his drawings, on film, and in interviews, becoming 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 his songs were adopted as anthems by the anti-war movement.

As of 2010, 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.

The Beatles were an English rock band, active throughout the 1960s and one of the most commercially successful and critically acclaimed acts in the history of popular music.[1] Formed in Liverpool, by 1962 the group consisted of John Lennon (rhythm guitar, vocals), Paul McCartney (bass guitar, vocals), George Harrison (lead guitar, vocals) and Ringo Starr (drums, vocals). Rooted in skiffle and 1950s rock and roll, the group later worked in many genres ranging from pop ballads to psychedelic rock, often incorporating classical and other elements in innovative ways. The nature of their enormous popularity, which first emerged as "Beatlemania", transformed as their songwriting grew in sophistication. They came to be perceived as the embodiment of ideals of the social and cultural revolutions of the 1960s.

Initially a five-piece line-up of Lennon, McCartney, Harrison, Stuart Sutcliffe (bass) and Pete Best (drums), they built their reputation playing clubs in Liverpool and Hamburg over a three-year period from 1960. Sutcliffe left the group in 1961, and Best was replaced by Starr the following year. Moulded into a professional outfit by their manager, Brian Epstein, their musical potential was enhanced by the creativity of producer George Martin. They achieved mainstream success in the United Kingdom in late 1962, with their first single, "Love Me Do". Gaining international popularity and acquiring the nickname "Fab Four" the following year, they toured extensively until 1966. During their subsequent "studio years", they produced what critics consider some of their finest material including the album Sgt. Pepper's Lonely Hearts Club Band (1967), widely regarded as a masterpiece. After their break-up in 1970, the band members all found success in independent musical careers. Lennon was murdered outside his home in New York City in 1980, and Harrison died of cancer in 2001. McCartney and Starr remain active.

The Beatles are the best-selling band in history,[2][3] and over four decades after their break-up, their recordings are still in demand. They have had more number one albums on the UK charts and have held the top spot longer than any other musical act. According to the RIAA, they have sold more albums in the United States than any other artist, and they headed Billboard magazine's list of all-time top Hot 100 artists in 2008. They have received 7 Grammy Awards from the American National Academy of Recording Arts and Sciences and 15 Ivor Novello Awards from the British Academy of Songwriters, Composers and Authors. They were collectively included in Time magazine's compilation of the 20th century's 100 most influential people.
