The first palaeographers to assert the Ms is in a humanist script?

[Beatrice]

Hello everyone

I am new here and I would like to ask you 

who were the first palaeographers to assert that the Ms is written in a humanist script. Does any member from this forum know something about that? Is there any paper about it?

I have been re-reading An Elegant Enigma by Mary D'Imperio as well as  Zandbergen's site. But I have not found  any palaeographer's name or an expert on Historiography and its techniques. Only Helmut Lehmann-Haupt, Consultant to H.P. Kraus, suggested that "[...] palaeographically speaking, Italy is a likely country of origin" (p.7)  

Nothing else.  Thanks.
