Yoko Ono (b. 1933) is a visionary, pioneering artist with a career that now spans over fifty years. During the 1950s in Tokyo, she introduced original questions concerning the concept of art and the art object, breaking down the traditional boundaries between branches of art. She has been associated with Conceptual art, performance, Fluxus, and happenings of the 1960s, and is one of very few women to have participated in these movements. Through her works of instructions and performances, as well as her activism, she has created a new kind of relationship with spectators in general and fellow artists, including her late husband John Lennon, inviting them to play an active part in the creative process. She also brings together two cultures – Eastern and Western – which extend and strengthen each other in continuous innovation.
