While Rainman is about someone with autism, Kim Peek himself was not autistic, though it seems they initially thought he was. I think the reason for this is because his social skills were quite good. He was born with something called FB Syndrome I think which resulted in brain deformities (complete lack of connections between left and right parts of this brain) and his abilities came from his brain finding ways to work around the problems, Which is quite ironic considering the people that complain that they wish everyone wouldn't think that everyone with autism was like Rainman!

Much of what scientists learned about Kim came in recent years and they on occasion revised what they believed about him. For example, they discovered he was not autistic. Scientists also learned that Kim could hold a book within eight inches of his face and read the left page with his left eye, the right with his right eye at the same time. He devoured books that way.
Whatever syndrome he had, he was a pretty unique individual with a warm heart. RIP Kim!
