LA TIMES - John Chamberlain obituary: American sculptor dies at 84, Dec 23, 2011

"By Christopher Knight, Los Angeles Times Art Critic

John Chamberlain, a prolific American sculptor whose use of crushed automobile sheet metal became his signature during a career that spanned half a century, died Wednesday in New York City. He was 84.
Reportedly in poor health, he had been working on a retrospective exhibition scheduled to open Feb. 24 at the Solomon R. Guggenheim Museum, his second at the Manhattan institution. The artist's death was announced by his wife, Prudence Fairweather, although no cause was given."
