I've found the author of Voynich manuscript. He was Giovanni Aurispa.

I hope Google made a mistake in translating.

This is not the case in this thread, because Rustandi has been very polite and nice.  But the behaviour of some "solvers", e.g. Cheshire, reminds me of the worst kind of mansplainers.   

It takes a certain degree of self-confidence to believe that you can be - and indeed are - the one to solve it when so many people before you, including expert cryptographers and linguists, have failed.  And to keep on at it when everyone else is telling you that you are wrong.

Women are often socialized to be less confident, to hedge our opinions, to second-guess ourselves, and to doubt and minimize our own abilities and expertise both to ourselves and others.  A lot of threads or publications by "solvers" tend to display the opposite behaviour.  For example, Cheshire claiming he succeeded where others failed because of his "special brain", and making basic mistakes in palaeography and linguistics while claiming experts in those areas were wrong. 

Of course you will still get confident female "solvers" (we have seen them), and it's probably not possible to ascertain gender-based trends from the data, especially if there are intervening variables, but it would be interesting.
