Jane Goodall, the world-renowned primatologist, conservationist, and U.N. Messenger of Peace, has passed away at 91, confirmed by the Jane Goodall Institute’s Taiwan chapter Thursday.

Goodall, best known for her groundbreaking research on chimpanzees in Tanzania, dedicated the latter part of her life to global conservation and environmental education. She died on Wednesday (Oct. 1), Pacific time.

President Lai Ching-te (賴清德) expressed condolences, calling Goodall “not only a giant of our times, but also a kind angel guarding nature.” Lai recalled walking with her along Tainan’s Erren River during his time as mayor, when she spoke of angels protecting the river. He said her tireless advocacy would remain in the hearts of the Taiwanese people.

Vice President Hsiao Bi-khim (蕭美琴) also paid tribute, quoting the Gospel of John in a Facebook post and praising Goodall’s lifelong devotion to primate research and sustainability. She said Goodall’s wisdom, courage and love of nature would continue to inspire future generations.

Goodall last visited Taiwan in June, encouraging young people not to give up hope and reminding audiences that “every single one of us makes a difference every day.” She first visited the island in 1996, later helping to establish the Taiwan branch of her Roots & Shoots youth program, which has since partnered with more than 1,000 schools on conservation projects.

Throughout her career, Goodall received numerous international honors, including the United States Presidential Medal of Freedom, French Legion of Honor, Japan’s Kyoto Prize, and Britain’s Dame Commander of the Order of the British Empire, and numerous others.

The Jane Goodall Institute’s Taiwan chapter said it would continue her mission, allowing hope to sprout through action.
