A couple of minor nits:

The original version of EMACS did not run under Unix.  Editor MACroS was a
collection of TECO programs and probably first ran under TOPS-10.  It is
probably the most thoroughly ported program in history, having been rewritten
from TECO to LISP to C over its long lifetime.  (TECO was created as a
paper-tape editor, which gives you some idea of just how old EMACS is!)

The original version of TeX did not run under Unix, either.  The exact order of
events escapes me, but TeX began as a SAIL program under either TOPS or WAITS. 
At some point it was rewritten in WEB, a language whose compiler produces
OS-neutral Pascal or C code.

Sorry, I just can't resist the urge to counteract Unix' astonishing power to
gather all of computing history under its umbrella.
