Jane Goodall
Jane Goodall is a British primatologist whose groundbreaking long-term study of wild chimpanzees in Tanzania transformed scientific understanding of primate behavior and human-animal relationships.
Goodall began her research in 1960 at Gombe Stream in Tanzania without a university degree, using patient observation methods that allowed her to document previously unknown chimpanzee behaviors, including tool use and complex social structures.
Her discovery that chimpanzees make and use tools challenged the long-held belief that tool use was a uniquely human trait, prompting renowned scientist Louis Leakey to declare that the definition of 'tool' and 'human' would need to be redefined.
Goodall later founded the Jane Goodall Institute and has spent decades as a global advocate for wildlife conservation, environmental education, and animal welfare, remaining an influential voice in conservation science.
