GNU Emacs also wasn't the first Emacs written in Lisp. Multics Emacs 
might have been the first, but there were other Emacs-like editors 
implemented in Lisp at MIT, Stanford, and CMU around the same time, I'm 
not sure which was actually first. GNU Emacs came much later than all of 
these, and it wasn't even the first one for Unix systems -- that would 
have been either Gosling Emacs or Z-Emacs.

Multics Emacs had the save-excursion macro, I think the others picked it 
up from there.
