Yoko Ono (オノ・ヨーコ, Ono Yōko?, born 小野 洋子(Ono Yōko) February 18, 1933) is a Japanese artist and peace activist, known for her work in avant-garde art, music and filmmaking, as well as her 1969 to 1980 marriage to John Lennon.
Dropping out of the graduate track program in philosophy at Tokyo's Peers School, Ono moved to New York in 1953 joining her immediate family who were already there. Quitting Sarah Lawrence College, she became involved in New York City's downtown artists scene, collaborating and working with members in and around the Fluxus group. An independent artist in her own right before meeting Lennon, both the media and the public were critical of her for years. She was repeatedly criticized for her influence over Lennon and his music, and blamed for the breakup of the Beatles: The couple's early years coincided with the band's final ones. Her experimental art was also not popularly understood, and, after Lennon's death, disagreements with Paul McCartney received as much as attention as her billboards and music releases, which the media usually advanced simply as attempts at self-promotion.
