Jim Dine (born 1935) is an American pop artist. He is sometimes considered to be a part of the Neo-Dada movement. He first earned respect in the art world with his Happenings. Pioneered with artists Claes Oldenburg and Allan Kaprow, in conjunction with musician John Cage, the "Happenings" were chaotic performance art that was a stark contrast with the more somber mood of the expressionists popular in the New York art world.
