Donald Triplett, the first person to ever be diagnosed with autism, passed away Thursday at the age of 89. Triplett was diagnosed as a child by Johns Hopkins psychiatrist Leo Kanner. Triplett, who was known as "Case 1", had an excellent memory and ability to recite music, but was socially withdrawn and had food aversions.
