When Robin Williams managed to make a gorilla laugh

In 2001, Robin Williams met Koko, a remarkable gorilla known for her ability to communicate through sign language. Koko, who had been taught to sign by American researchers, displayed an intelligence that blurred the lines between humans and other primates. However, at the time of their meeting, Koko was struggling with grief. She had recently lost her close companion, Michael, another gorilla, and had been in mourning for months.

Researchers were concerned about Koko’s emotional state and hoped that meeting Williams, known for his warmth and humor, might lift her spirits. Williams, though unsure of what to expect, agreed to the visit.

The moment they met, something extraordinary happened. Williams, always gentle and playful, allowed Koko to approach him on her own terms. She quickly took an interest in him, particularly his glasses, which she examined with fascination. As they interacted, Koko warmed up to him, initiating playful gestures, tickling, and even engaging in a silent conversation through sign language. The two bonded instantly, sharing moments of joy and laughter. For the first time since her friend’s passing, Koko laughed again.

The researchers were astonished—not only had Williams connected with Koko, but he had also helped her emerge from her sorrow, even if just for a while. When asked to describe Williams, Koko signed the word “friend.”

Deeply moved by the experience, Williams maintained a connection with Koko and later participated in awareness campaigns for the protection of endangered species and ethical treatment of animals. Their bond remained strong, and years later, when Koko learned of Williams’ passing in 2014, she showed visible grief, signing the word “cry” and retreating into a somber silence.

Koko lived for four more years, passing away in 2018 at the age of 46. She remains one of the most extraordinary primates studied in scientific history, not just for her linguistic abilities but for demonstrating the depth of emotional connection possible between species.
