...died at age 58. From the obit in the New York Times:
Mr. Peek was not autistic — not all savants are autistic and not all autistics are savants — but he was born with severe brain abnormalities that impaired his physical coordination and made ordinary reasoning difficult. He could not dress himself or brush his teeth without help. He found metaphoric language incomprehensible and conceptualization baffling.
But with an astonishing skill that allowed him to read facing pages of a book at once — one with each eye — he read as many as 12,000 volumes. Even more remarkable, he could remember what he had read.
Mr. Peek had memorized so many Shakespearean plays and musical compositions and was such a stickler for accuracy, his father said, that they had to stop attending performances because he would stand up and correct the actors or the musicians.
“He’d stand up and say: ‘Wait a minute! The trombone is two notes off,’ ” Fran Peek said.
