Last year, a female chimpanzee in her late 40’s named Dorothy died of heart failure at a rescue and rehabilitation center in Cameroon. She’d lived there for 8 years, helping other chimpanzees transition from various traumas. National Geographic tells the story:

After a hunter killed her mother, Dorothy was sold as a “mascot” to an amusement park in Cameroon. For the next 25 years she was tethered to the ground by a chain around her neck, taunted, teased, and taught to drink beer and smoke cigarettes for sport. In May 2000 Dorothy—obese from poor diet and lack of exercise—was rescued and relocated along with ten other primates. As her health improved, her deep kindness surfaced. She mothered an orphaned chimp named Bouboule and became a close friend to many others, including Jacky, the group’s alpha male, and Nama, another amusement-park refugee.

Szczupider, who had been a volunteer at the center, told me: “Her presence, and loss, was palpable, and resonated throughout the group. The management at Sanaga-Yong opted to let Dorothy’s chimpanzee family witness her burial, so that perhaps they would understand, in their own capacity, that Dorothy would not return. Some chimps displayed aggression while others barked in frustration. But perhaps the most stunning reaction was a recurring, almost tangible silence. If one knows chimpanzees, then one knows that [they] are not [usually] silent creatures.”

The rest of the story is presumably in chimpanzee, and likely three times as sad.
