Surely not. Maclisp (which predates C) also represented characters as fixnums:
Maclisp #/x was equivalent to Emacs Lisp ?x. So the heritage runs through
Cambridge, not through Murray Hill.

Disclaimer: I never used Maclisp (I jumped straight from Lisp 1.5 to Emacs Lisp
and Scheme) and of course Richard is the authority here.
