Conservationist Jane Goodall dies at 91

(CNN) – The woman who changed the way the world looks at wildlife is gone.

Legendary conservationist Dr. Jane Goodall died Wednesday of natural causes, according to her namesake institute.

Officials there say Goodall was “a tireless advocate for the protection and restoration of our natural world.”

Goodall’s field work with chimpanzees included documentation of the primates’ emotions and personality traits.

She is also credited with changing the overall way scientists study animals.

Goodall, who had been on a speaking tour of the U.S. when she died, was 91 years old.
