In 1974, Dr Patterson and Dr Ronald Cohn moved Koko and the project to Stanford and went on to establish The Gorilla Foundation.



While at Stanford the project expanded to include a second western lowland gorilla, Michael.

Koko’s capacity for language and empathy opened the minds and hearts of millions.

She was featured in multiple documentaries and appeared on the cover of National Geographic twice.
