Actually the original TECO Emacs was written by Guy Steele, RMS took it over later. I remember using this on Tops-20.
James Gosling wrote an Emacs in C, to run on Unix. It had a "Mocklisp" macro language. I remember reading the source code at CMU.
RMS then wrote GNU Emacs, with the better "elisp" macro language.
Both of these were inspired by the Emacs written in MacLisp by Bernie Greenberg.
