John Chamberlain, who created sculptures...

...from old auto parts, died at age 84. From the Times (my emphasis):

In a restless career of almost half a century, Mr. Chamberlain worked with a broad range of materials, some as pliant as foam rubber and as ephemeral as brown paper bags. But he returned again and again to the more substantial stuff of the scrap yard, explaining the attraction as one of practicality. “I saw all this material just lying around against buildings, and it was in color,” he said, “so I felt I was ahead on two counts.”

Mr. Chamberlain felt that even the word “sculpture” was limiting in describing art that, while functioning in three dimensions, could be made from almost anything.

“A sculpture is something that if it falls on your foot, it will break it,” he said. (Well into his career, some people still had a tough time seeing his sculptures as works of art; in 1973, two 300-pound metal pieces were mistaken for junk and carted away as they sat outside a gallery warehouse in Chicago.)
