Yoko Ono is a Japanese artist, musician, activist, and filmmaker. 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 widely known outside the fine art world 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. The couple used their honeymoon as a stage for public protests against the Vietnam War with what they called a bed-in. She and Lennon remained married until he was murdered in front of the couple's apartment building, The Dakota, on December 8, 1980. Together, they had one son, Sean, who later also became a musician.
Ono began a career in popular music in 1969, forming the Plastic Ono Band with Lennon and producing a number of avant-garde music albums in the 1970s.
