Erik Arneson
Erik Arneson is a Person who really likes Common Lisp. He hasn't written anything in Common Lisp that's suitable for public consumption, but he does have some handy Emacs Lisp hacks on his web page.

Finally, this possibly delusional man believes he's the only Lisp-using Freemason. If you can prove him wrong, please tell him so. He is not a weirdo, thankfully.
