Don Triplett, the first person diagnosed with autism, dead at 89

Triplett was known worldwide as “Case 1″ - the first person to be diagnosed with autism.

Triplett worked at the bank for about 65 years, according to CEO Allen Breland, whose own 36-year tenure makes him a relative newcomer there.

“Don was a remarkable individual,” Breland said of the fiercely independent savant. “And he kept things interesting.”

Though he came across to newcomers as strange and obsessive, Triplett had a facility with numbers that made phone directories obsolete in his presence.
