# Bill Schelter

**William Frederick Schelter** (died July 30, 2001) was a professor of mathematics at the University of Texas at Austin and a Lisp developer and programmer. Schelter is credited with the development of GNU Common Lisp (gcl) implementation of Common Lisp and the GPL'd version of the computer algebra system Macsyma called GNU Maxima. He is also credited with the first port of the GNU C compiler to the INTEL 386 architecture, used in the original implementation of the Linux kernel [1].

Schelter obtained his Ph.D. at McGill University in 1972. His mathematical specialty was computational algebra and its applications, including automated theorem proving in geometry.

In the summer of 2001 he died suddenly of a heart attack while travelling in Russia.
