Autism is first diagnosed in 1911 and Asperger's in 1944.

It wasn't commonly diagnosed during any of these people's lives, so you're not going to find conclusive evidence.

None of them were diagnosed (obviously not Newton).

So you're only going to find people arguing over straws.

absence of evidence is not evidence of absence

There is no strong evidence to go on.

What are you arguing?

They have Autism until proven otherwise?

About 0.5% of people were diagnosed with Autism before 1990: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4113600/

If we're making assumptions, statistically, we'd probably want to assume the other way.
