John Winston Ono Lennon[nb 1] (born John Winston Lennon; 9 October 1940 – 8 December 1980) was an English singer, songwriter and musician who gained worldwide fame as the founder, co-songwriter, co-lead vocalist and rhythm guitarist of the Beatles. His work included music, writing, drawings and film. His songwriting partnership with Paul McCartney remains the most successful in history.[3]

Born in Liverpool, Lennon became involved in the skiffle craze as a teenager. In 1956, he formed the Quarrymen, which evolved into the Beatles in 1960. Sometimes called "the smart Beatle", Lennon initially was the group's de facto leader, a role he gradually ceded to McCartney. Through his songwriting in the Beatles, he embraced myriad musical influences, initially writing and co-writing rock and pop-oriented hit songs in the band's early years, then later incorporating experimental elements into his compositions in the latter half of the Beatles' career as his songs became known for their increasing innovation. Lennon soon expanded his work into other media by participating in numerous films, including How I Won the War, and authoring In His Own Write and A Spaniard in the Works, both collections of nonsense writings and line drawings. Starting with "All You Need Is Love", his songs were adopted as anthems by the anti-war movement and the larger counterculture of the 1960s. In 1969, he started the Plastic Ono Band with his second wife, multimedia artist Yoko Ono, held the two-week-long anti-war demonstration Bed-ins for Peace and left the Beatles to embark on a solo career.
