Last week we received the news that Jane Goodall had died.
Jane was not only a pioneering scientist who transformed our understanding of chimpanzees but also an extraordinary human being whose compassion and wisdom touched millions around the world.
So, we wanted to revisit this conversation I had with her, it's a chance to hear,
in her own words, the story of her remarkable life and the passion that drove her work.
Jane Goodall shot to fame in December 1965 when she appeared on the cover of National Geographic magazine.
Through magazine and newspaper articles, scientific papers, books, documentary films,
she's introduced millions of people around the world to the social and emotional lives of the wild chimpanzees of Gombe in eastern Tanzania.
When the alpha female Flo died back in 1972, she was so well loved she had an obituary in the times.
Jane's observations made over many years changed the way we viewed our closest animal relatives and made us think about what it is to be human.
