PaIk is widely recognised as the founding father of video art. Stockhausen was a colleague at an electronic music studio in Germany. Ono was an early friend — she said he taught her by being himself. He helped Maciunas and Vostell inaugurate Fluxus, and started a great friendship with Cage by cutting off his tie. Moorman (extensively) and Beuys were collaborators; other friends who featured in, contributed to or were dedicatees of his video works included Kaprow, Ginsberg, Cunningham, Gage, Breer, Beck and Malina. Viola as a young technician/artist first met him at an Italian video studio, and as a friend spoke at his funeral.
