A primatologist who not only impacted accepted views of humanity and drastically changed the evolutionary theory of man, but also influenced the development of theories in behavioral science. Through thirty years of continuous observation of free-living chimpanzees at the Gombe National Park on the northeast coast of Lake Tanganyika, she elucidated their behavior, society, and ecology. She thereby demonstrated that certain behavior and abilities, which were considered intrinsic only to human beings, were actually present in the society of chimpanzees as well.

*This field then was Field of Biological Sciences (Behavior, Ecology and Environment).
