On the character of Wilfrid Voynich

[ReneZ]

Voynich may have honestly believed that the VMS was Bacon's at first.  But he was soon told by all experts that it could not possibly be. 

He never had any pushback like that. Quite the contrary, there were scholars supporting the Bacon
authorship, Newbold was on his way to prove it from the text, and Prof. James Westfall Thompson was on his way to find a trace of an encrypted genuine Bacon manuscript as late as 1926.

Manley, who was quite suspicious of the Bacon origin, waited until after Voynich's death to publish his devastating paper.
