Yoko Ono (小野 洋子, Ono Yōko?, born 18 February 1933), is a Japanese multimedia artist, singer, and peace activist. She is the widow and second wife of John Lennon and is also known for her work in avant-garde art, music, and filmmaking.
Ono grew up in Tokyo, and studied at Gakushuin. She withdrew from her course after two years and rejoined her family in New York in 1953. She spent some time at Sarah Lawrence College, and then became involved in New York City's downtown artists scene, including the Fluxus group. She first met Lennon in 1966 at her own art exhibition in London, and they became a couple in 1968. Ono and Lennon famously used their honeymoon as a stage for public protests against the Vietnam War with their Bed-Ins for Peace in Amsterdam and Montreal in 1969. She brought feminism to the forefront in her music, influencing artists as diverse as the B-52s and Meredith Monk. Ono achieved commercial and critical acclaim in 1980 with the chart-topping album Double Fantasy, released with Lennon three weeks before his death.
