And again... why is it that people are pluralising him all the time?
With a "j" sound, "to asperge" is "To sprinkle, besprinkle." Properly, the device for flicking holy water around in a church is an aspergillum, but calling it an "asperger" might be valid. If you had two of them, they would then be "aspergers". (Or maybe that would be the people waving their aspergilliums around?)
Hans Asperger was Austrian, hence his name is pronounced with a hard "g" sound. If several of his family were to be gathered together, they would be "Aspergers".
However, when what Hans described "autistic psychopathy" was rediscovered by Lorna Wing and Uta Frith, they called it "Asperger syndrome". The DSM seems to have tried to change "syndrome" to "disorder", and I rather hope that never catches on.
Introducing the possessive "'s" makes it a little more consistent with other medical terms... hence we now tend to use "Asperger's syndrome" and (spit, spit) "Asperger's disorder".
As only one diagnosis has been named after Hans, truncating the "syndrome" is acceptable, hence the abbreviated "Asperger's".
