This is a wholesale misrepresentation intended, in would seem, to merely
slander the school of thought with which Felsenstein retains so much
disdain.  In the first place, none in the phylogenetic systematics
school would have much reason to reference UPGMA at all for obvious
reasons, and so Felsenstein's comment is irrelevant.  Secondly, no one
ever has attributed UPGMA to Hennig.  Third, a mere cursory reading of
the literature will demonsatrate that cladists were more aware of the
origins for numerical methods than many others (e.g., Nelson's
revisiting Jardine's work).  That Hennig did not happen to use the word
"parsimony" hardly means that Camin and Sokal originated the idea. 

Rather than taking Felsenstein's ipse dixit, the scholarly student would
be wise to read Farris, J. S. and Kluge, A. G. 1997. Parsimony and
History. Syst Biol 46: 215, and references therein.
