In computer programming, Franz Lisp was a Lisp system written at UC Berkeley by the students of Professor Richard J. Fateman, based largely on Maclisp and distributed with the Berkeley Software Distribution (BSD) for the Digital Equipment Corp (DEC) VAX. Piggybacking on the popularity of the BSD package, Franz Lisp was probably the most widely distributed and used Lisp system of the 1970s and 1980s.
