Michael (gorilla)

Michael (March 17, 1973, Cameroon – April 19, 2000) was a male gorilla involved in experiments to teach apes sign language. He is alleged to have had a working vocabulary of over 600 signs in American Sign Language, taught to him by Koko, a female gorilla; Francine Patterson; and other staff of Stanford University. Michael, an orphan, spent most of his life in Woodside, California, where he became known for painting. Both Michael and Koko’s linguistic abilities are widely rejected by specialists, despite popular perception to the contrary.
