Daniel Keyes, the MD who wrote the classic science fiction novel Flowers for Algernon, has died at 86, of complications from pneumonia. I met Keyes when he received the Science Fiction Writers of America's Author Emertius honor in 2000, and he struck me as a sensitive and thoughtful person. He told the story of how he'd conceived of Algernon while riding the subway to his medical residence, and how pleased he'd been with its reception (it's also one of the small handful of science fiction novels whose film adaptation is in the same league as the book -- the 1968 film "Charly" won its lead an Academy Award).

Algernon is a truly fantastic contribution to literature -- a book that has stayed with me for decades and influenced the way I think about intelligence, science, medicine, and self-determination. Though Keyes never wrote another science fiction work that attained its success, that book alone earned him a richly deserved place in history. (via /.)
