From the Monterey County Herald:
Allan Kaprow, an artist who in the 1950s pioneered an unrehearsed, nonverbal form of theater called a ”happening” that was intended to shatter the boundary between art and life, has died. He was 78.
Kaprow, who taught for years at the University of California-San Diego, died Wednesday at his home in Encinitas. He had been ill for some time and died of natural causes, said friend Tamara Bloomberg.
Kaprow’s happenings took place in real-life settings and involved unrelated or bizarre scenes acted out by willing participants. The audience was made up of people who happened to be there.
Born August 23, 1927, in Atlantic City, N.J., Kaprow called himself an ”un-artist.” He was primarily a painter and sculptor working with found objects.
