Chimpanzee Who Knew Sign Language Dies

”Washoe”Washoe, a female chimpanzee said to be the first non-human to acquire human language, has died of natural causes at the research institute where she was kept.

Washoe, who first learned a bit of American Sign Language in a research project in Nevada, had been living on Central Washington University's Ellensburg campus since 1980. Her keepers said she had a vocabulary of about 250 words, although critics contended Washoe and some other primates learned to imitate sign language, but did not develop true language skills.

She died Tuesday night, according to Roger and Deborah Fouts, co-founders of The Chimpanzee and Human Communications Institute on the campus. She was born in Africa about 1965.
