Few people change how the world thinks, but Jane Goodall, born in 1934 in London, England, did exactly that. She is remembered for her long study of wild chimpanzees.
Goodall was patient. She sat quietly in the forest for months before the chimpanzees let her come close.
In 1960, Goodall arrived at Gombe in Tanzania to study chimpanzees. In 1960, Goodall saw a chimpanzee use a twig as a tool to catch termites.
Then, in 1977, Goodall founded the Jane Goodall Institute to protect chimpanzees. In 1991, Goodall started Roots & Shoots, a program for young people to help animals and the environment. (Observation: carefully watching something to learn about it.)
Goodall died in 2025. Her discovery that chimpanzees make tools changed what scientists believed about animals.
