Yoko Ono (Japanese: 小野 洋子, romanized: Ono Yōko, usually spelled in katakana オノ・ヨーコ; born February 18, 1933) is a Japanese multimedia artist, singer, songwriter, and peace activist. Her work also encompasses performance art and filmmaking. Ono grew up in Tokyo and moved to New York City in 1952 to join her family. She became involved with New York City's downtown artists scene in the early 1960s, which included the Fluxus group, and became well known in 1969 when she married English musician John Lennon of the Beatles, with whom she would subsequently record as a duo in the Plastic Ono Band.
