Oh. My. Gosh. How could you miss Andrew Jackson "Slipstick" Libby? Add him right in and change 60% of the votes so far to him on the conservative assumption that at least that portion of the crowd would have voted for him.
OK, in case you've never heard of him, he's a talented mathematician and "lightning calculator" that appears in several of Robert Heinlein's science fiction novels, including being a recurring character in his "future history."
Or must I vote for Charlie Epps? :-)
