Penny Patterson, a graduate student at Stanford University, met Koko, a new-born gorilla in San Francisco Zoo back in 1971. She was fascinated by other ape language experiments taking place at that time and decided to try to teach Koko sign language. What started out as a scientific experiment evolved into a unique relationship which, for almost half a century, has challenged the way we think about animals and changed the course of many lives.
