early Lisp on UNIX: Franz Lisp (80s).

@symbolics I suspected that Franz may have been ported to Unix eraly-on, but I had a hard time finding evidence of it, so thanks for confirming that!

Most people consider Stallman’s Emacs to be the origin of Emacs back in 1976-ish based on the TECO editor, even though the Emacs of that era would probably be unrecognizable to us nowadays. Greenberg wrote Emacs in MacLisp in 1978, and so I think that was the first Emacs Lisp, but this was running on ITS, not Unix.

I understand that Emacs already had quite a following by the time Gosling Emacs was officially released in 1984, and Stallman’s GNU Emacs v15 released in 1985 saw wide-spread distribution as a result.

So I guess Franz was indeed probably the first Lisp to run on Unix.
