*THE* guy? What about Stallman? I thought the history of Emacs went more
like:
1. Stallman writes Emacs as Editor MACroS for TECO.
2. Gosling writes "Unix Emacs". I remember a sentence in the
introduction of the manual that went something like, "Calling this editor
'Emacs' is presumptuous and perhaps a bit dangerous."
3. Stallman writes GNU Emacs, borrowing some code (screen management?)
from Unix Emacs.
