What, exactly, is the evidence that Vincennes or Wisconsin Lisp
were milestones or that Vincennes was in any sense an ancestor
of Scheme?  

Of course, there are a number of significant Lisps between Lisp 1.5
and MacLisp/InterLisp as well as at other interesting points.  In
particular, one might mention PDP1 Lisp and BBN Lisp on the way to
Interlisp, Q-32 Lisp, Stanford Lisp 1.6 and UCI Lisp, Cambridge Lisp,
PSL, Lisp/VM (and related Lisps), Le Lisp, LM/ZetaLisp, NIL, Spice
Lisp, and of course Lisp 2.  But in a "short history" it is not
necessary to mention everything.
