Donald Triplett, the first person ever to be diagnosed with autism, passed away on 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 Triplett, who was known as “Case 1”, had an excellent memory and ability to recite music, but was socially withdrawn and disliked food.
Kanner started seeing Triplett in 1938 when he was 5 years old. Triplett featured heavily in Kenner’s 1943 paper, “Autistic Disturbances of Affective Contact.”
Triplett worked for 65 years at the Bank of Forest, where his father Beamon was the main shareholder. He was born in Mississippi and graduated from Millsaps College in 1958.

“Don was a remarkable person,” CEO Allen Breland told WLBT. “And he kept things interesting.”
Triplett was also a savant with unusual math skills. He was extensively studied in publications ranging from medical journals to a book called “In a Different Key”.
“He was in his own world, but if you gave him two-, three-digit numbers, he could multiply them faster than you could get the answer on a calculator,” Breland explained.

Triplett’s special interests included golf and travel, and according to Breland, he regularly visited “exotic locations”.
Triplett’s cousin Oliver told The Times-Picayune/The New Orleans Advocate that his uncle’s legacy gives hope to parents of autistic children.
“They can see Don and a community that hugged him,” Oliver explained. “As a whole, Forest encouraged and accepted him. It gives people who have children on different levels of the spectrum hope that their children can live happy and full lives.”
