Humphrey was a top-ranking male chimpanzee in Gombe National Park, Tanzania, in the early 1970s and known for his frequent attacks on other chimps. Tensions between Humphrey and his southern rivals Charlie and Hugh may have triggered the only known civil war in wild chimpanzees, researchers say. | Geza Teleki
