Animal rights campaigner and chimpanzee expert Dame Jane Goodall has died at the age of 91.
In announcing her death, the Jane Goodall Institute, said she was in California where she was set to appear as part of a speaking tour.
The Institute described her as a tireless advocate for the protection and restoration of the natural world.
Dame Jane Goodall was not only a world-renowned conservationist, primatologist and ethnologist, but also a UN Messenger of Peace.
But she is perhaps best known for her ground breaking study in the 1960s on the chimpanzees of the Gombe, in Tanzania, which altered forever the accepted definition of humanity.
Kathryn spoke to Jane Goodall when she was on a speaking tour of New Zealand in 2017.
