Born in London in 1934, Goodall visited Kenya in 1957. There, she started working for paleoanthropologist Louis Leakey, studying primate behavior in Tanzania.
Hailed as the only human to have been accepted into chimpanzee society, Goodall's intimate and close proximity to the community allowed her to reach a number of conclusions on our shared emotional spectrum of behavior and reason.
Her work at Gombe Stream also disproved the accepted notion that only humans could make and use tools, and that chimpanzees were vegetarians.
