Once dubbed “The Artist Who Invented Video Art,” Nam June Paik was an incredibly prolific and amusing conceptual artist from Korea in the postwar era; he is most associated with his works incorporating the cathode ray tube (we usually call it a TV set), including “TV-Buddha,” “TV Chair,” and “Family of Robot,” the last of which is essentially a series of robots made out of TV sets. Earlier in his career Paik was associated with John Cage, particularly his notorious 1960 work “Etude for Piano,” which culminated in Paik cutting off Cage’s necktie and washing Cage’s hair with shampoo. In 1969 Paik teamed up with Fluxus-associated filmmaker Jud Yalkut to create Beatles Electroniques, a three-minute video in which Beatles footage is messed with electronically.
