This stuff is from memory, but you shouldn't have much trouble sourcing it ...
There is Asperger's original paper, which was dusted off and translated by Lorna Wing, "On Autistic psychopathy in children."
You will see that Asperger took a remarkably positive view and states over and over that Aspies are valuable and creative people. He said that "for succes in the arts and sciences, it
seems that a dash of autism is essential."
Asperger was working in Austria during the Nazi occupation. It is speculated that he may have been protecting subjects from the Nazi death camps, he took great care to point out they make excellent scientists and civil engineers.
It is further speculated that Asperger himself was Aspie.
Asperger's clinic was bombed out by an Allied air raid, destroying his clinic, killing his partner and possibly some of his subjects.
His seminal thesis was essentially lost in the rubble of WW II, and sat unnoticed at U Cambridge
until Lorna Wing found it.
He was probably the first neurodiversity advocate.
Hope some of this helps ...
