Washoe, Believed To Be The First Chimpanzee To Learn Sign Language, Dies

Washoe, a female chimpanzee believed to be the first non-human to acquire human language, has died of natural causes at a research institute.

Washoe, who learned American Sign Language in a research project
in Nevada, died Tuesday night at the Chimpanzee and Human Communication Institute at Central Washington University's Ellensburg campus, said institute co-founders Roger and Deborah Fouts.

She was born in Africa about 1965.

A memorial is planned for Nov. 12.
