Jane Goodall has studied chimpanzees in Africa since 1960. She arrived in Tanganyika with no training but a lot of enthusiasm for the work ahead. Fifty years later, she is still working for the benefit of the chimpanzees she loves. National Geographic has an extensive retrospective of her life and work in the new issue, with plenty of photographs as well. Link -Thanks, Marilyn Terrell!
In addition, NatGeo has digitized and archived all the articles they've done on Jane Goodall and her work since 1960. Link
