My Friends, the Wild Chimpanzees by Jane Goodall,Hugo van Lawick,National Geographic Society (U.S.). Special Publications Division

In 1960 a young Englishwoman named Jane Goodall embarked on a daring scientific adventure: the study of chimpanzees in the wild. Encouraged and aided by Dr. Louis B. Leakey, she traveled hundreds of miles across East Africa to reach the remote Gombe Stream Game reserve on the shores of Lake Tanganyika. There she found the powerful and potentially dangererous wild chimpanzee. This book tells of the drama, the humor, the challenges, and the rewards of her years of exhaustive research along with telling the life stories of her chimpanzee acquaintances enhanced with 166 color photographs.
