For Lorna Wing’s translation of Hans Asperger’s original paper, see:
Frith, U. (Ed.) (1991). Autism and Asperger syndrome. Cambridge, UK: Cambridge UniversityPress
Asperger’s Syndrome was virtually unknown in the west, while Leo Kanner’s work on Autism was widely known. This is primarily due to the fact that Asperger was working in Austria in and around WWII, while his compatriot, Kanner, had emigrated to the United States.
