John Winston Ono Lennon was an English musician and activist. He gained global fame as the founder, co-lead vocalist and rhythm guitarist of the Beatles. Lennon's songwriting partnership with Paul McCartney remains the most successful in history.
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. He initially was the group's de facto leader, a role he gradually seemed to cede to McCartney, writing and co-writing songs with increasing innovation, including "Strawberry Fields Forever", which he later cited as his finest work with the band.
