Koko the gorilla just died. This happened when I was travelling with my students. I told them, and it turned out that many of them had never heard of her. Koko was a western lowland gorilla who was particularly known for having learned over 1000 signs in American Sign Language. She was a skilled communicator who proved that gorillas are capable of empathy, compassion, and grief. In her travels, she met many famous people including Robin Williams and Mr. Rogers. I followed her since I was a young girl and will miss her. RIP Koko.
