About the Author
CHRISTOPHE BOESCH is an evolutionary biologist and the director of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany. After first visiting the Ivory Coast in 1976, he returned in 1979 to begin a long-term study of the Ta forest chimpanzees. He has published many papers and a number of books, including Wild Cultures: A Comparison Between Chimpanzee and Human Cultures
. Concerned about the continuing deforestation in Africa, Christophe founded the Wild Chimpanzee Foundation to fight for their survival. Hedwige, his wife, says that Christophe has an uncanny ability to predict what the chimpanzees will do when he's following them in the forest.
SANJIDA O'CONNELL earned her Ph.D. in chimpanzee intelligence and then went on to direct a number of documentaries for the BBC, as well as National Geographic and the Discovery Channel, including Demonic Ape
and a three-part series on animal intelligence called Animal Minds
. She has also worked as a wildlife presenter for the BBC and has had four critically acclaimed novels and three nonfiction books published. She writes on environmental issues and science for national newspapers and magazines. For her doctorate, she studied sign language, which is used to communicate with chimpanzees; now that she has a daughter, it's becoming very useful.
