Biography: Anthony D. Cox (born 1937) is an American film producer and art promoter. He is a former husband of Yoko Ono. Cox met Yoko Ono in 1961, after he saw some of her art work in an anthology and located her in Tokyo, Japan. The couple married on November 28, 1962, but the marriage was annulled on March 1, 1963, due to Ono neglecting to officially finalize her divorce from her first husband, the Japanese composer Toshi Ichiyanagi. They remarried on June 11, 1963, two months before their daughter, Kyoko Chan Cox, was born on August 8, 1963. Cox became a full-time caregiver for Kyoko, while both he and Ono continued with their art, collaborating as conceptual artists.
