Kyoto Common Lisp...

GCL (http://www.gnu.org/software/gcl/)

History 

GCL is the product of many hands over many years. The original effort was known as the Kyoto Common Lisp system, written by Taiichi Yuasa and Masami Hagiya in 1984. In 1987 new work was begun by William Schelter, and that version of the system was called AKCL (Austin Kyoto Common Lisp). In 1994 AKCL was released as GCL (GNU Common Lisp) under the GNU public library license. The primary purpose of GCL during that phase of it's existence was to support the Maxima computer algebra system, also maintained by Dr. Schelter. It existed largely as a subproject of Maxima.

別のサイトでさっき知った・・・。KClがGCLになったのかーー。
すげぇ。。。
湯浅さんと萩谷さんが書かれたLisp本を学校から借りてるので是非熟読したいです。笑
