Burden is a performance artist who emerged as part of the American art scene in the 1970s, performing controversial, dangerous pieces in which he used his own body as the art medium. During a 1971 performance piece titled Shoot, he was shot in his left arm by an assistant standing a short distance away. He was labeled insane following the performance, but it has since become one of his most well-known pieces from the period. Why did he resign from the University of California in 2005? Discuss
