What exactly is Asperger’s Syndrome? Until recently, the high-functioning form of Autism was largely unknown to the public and even to those who suffered from the illness. We’ll spend the hour with one such person. John Elder Robison is a self-described “machine aficionado” who restores high-end automobiles and even created and built fire-shooting guitars for the band KISS. Robison joined us in January to discuss his best-selling book “Look Me in the Eye: My Life with Asperger’s” (Crown, 2007).
