The story of the discovery of autism and the first child diagnosed with the disorder draws on extensive research to trace how understandings about the condition have evolved through eight decades and how it has affected families in different historical periods.
In researching their book, Caren Zucker and John Donvan tracked down Donald Gray Triplett (center), the first person officially diagnosed with autism. Now in his 80s, Triplett has had a long, happy life, Donvan says, maybe partly because his hometown embraced him from the beginning as " 'odd, but really, really smart.' "
