Goodall feels even the most unsociable chimps should be helped, at the very least by improving their caged environments. In 1992, she started working to raise money for Gregoire, a chimp at the Brazzaville Zoo in the Congo. He'd plucked out all his hair. There, she received Gregoire's embrace. Her institute and volunteers also help with two other adult chimpanzees at the Brazzaville Zoo and 24 young orphans in the Entebbe Wildlife and Conservation Center in Uganda.
