John Lennon was a founding member of The Beatles, one of the most influential rock bands in history. The Beatles evolved from Lennon's first band The Quarrymen and achieved worldwide success in the early 1960s. Some of their most popular albums included Sgt. Pepper's Lonely Hearts Club Band and Abbey Road. After The Beatles split up in 1970, Lennon had a successful solo career but was tragically assassinated outside his New York apartment in 1980 by Mark David Chapman.
