A story of Robin Williams and a gorilla names Koko 🐾🙏🏼
Robin Williams once brought laughter back to a grieving gorilla who had been mourning the loss of his friend for six months. This remarkable story began when American ethologists taught a gorilla named Koko to communicate with humans using sign language. Koko was exceptionally intelligent, but he was going through a deeply difficult period, to the point where biologists feared he might be suffering from severe melancholy.
The researchers wanted to help Koko by finding him a new companion while also studying how he interacted with humans. Since Koko had learned sign language and could communicate with our species, he was the perfect subject to explore whether there were true cognitive boundaries between humans and gorillas. To assist, they reached out to Robin Williams, the renowned comedian, and asked if he would spend time with Koko, interacting with him naturally, as if he were simply a person in need of comfort.
Williams agreed, though he had reservations. He wasn’t an expert on primates and worried he might be too awkward to connect with the gorilla. However, when he met Koko, Williams had an unexpected revelation. By letting the gorilla approach him at his own pace, Williams realized that interacting with Koko felt like engaging with a curious child. Gradually, Koko grew more interested in his visitor, even becoming fascinated by Williams’ glasses, which he referred to as "strange glass eyes."
Soon, Koko began communicating with Williams through sign language, suggesting games and asking surprisingly insightful questions that left the actor stunned. Within minutes, the two were joking, tickling each other, playing, and sharing stories from their lives. The researchers were amazed and asked Koko to describe Williams in one word. The gorilla chose the term "friend."
Williams was deeply moved by the encounter, especially when he learned that he had managed to make a gorilla laugh who was on the brink of depression due to loneliness. Inspired, he decided to visit Koko whenever possible and even filmed public service announcements with him, advocating for species conservation and against animal experimentation.
The bond between Koko and Williams was so profound that it endured even after the actor’s death in 2014. When Koko learned of Williams’ passing, he asked his instructors if he could cry and spent days in quiet reflection, his lips trembling with grief. The gorilla was inconsolable, knowing he would never see his friend again.
Koko passed away four years later, in 2018, at the age of 46. Today, he is remembered as one of the most significant primates in the history of scientific research, a testament to the extraordinary connections that can exist between species.
