Goodall’s discoveries as an ethologist revolutionized science, and she was a tireless advocate for the protection and restoration of our natural world.

It was July 1960 when Goodall, 26 years old at the time, first entered Tanzania and began her important research on chimpanzees in the wild. Throughout her study of the species, Goodall proved that primates display an array of similar behaviors to humans, such as communicate, develop individual personalities and make and use their own tools.
