Dr. Jane Goodall, the pioneering primatologist, conservationist, and UN Messenger of Peace, passed away on October 1, 2025, at age 91 in California while on a U.S. speaking tour, leaving behind an enduring legacy of hope, scientific innovation, and tireless advocacy for wildlife and humanity. Born Valerie Jane Morris-Goodall on April 3, 1934, in London to a businessman father and novelist mother, she grew up with a profound curiosity for animals, inspired by a stuffed chimpanzee toy named Jubilee that sparked her lifelong passion. At 26, with minimal formal training but boundless determination, Goodall ventured to Tanzania’s Gombe Stream National Park in 1960, embarking on what became the longest-running study of wild chimpanzees, revolutionizing ethology by observing their tool use, social bonds, and complex behaviors.

Her groundbreaking discoveries challenged scientific norms; naming chimpanzees like David Greybeard and Flo instead of numbering them humanized the research, proving empathy could coexist with objectivity and opening primatology to women. Goodall documented not only joyful maternal bonds and friendships but also darker aspects like aggression and cannibalism, including the “Gombe Chimpanzee War,” reshaping views on primate sentience and evolution. Supported initially by National Geographic and photographer Hugo van Lawick—whom she married in 1964—her work gained global acclaim, earning her the Kyoto Prize in 1990 and a damehood in 2004.

Transitioning from field scientist to advocate, Goodall founded the Jane Goodall Institute (JGI) in 1977 to protect chimpanzees and habitats, expanding into community-centered conservation like the TACARE program in Tanzania, which integrates local needs with environmental protection. JGI now operates in 25 countries, supporting sanctuaries such as Tchimpounga in Congo and Chimp Eden in South Africa, while combating threats like deforestation and poaching. Her 1991 Roots & Shoots youth program, born from Tanzanian campfire talks, empowers over a million young people in 100+ countries to lead community projects for animals, people, and the environment, embodying her mantra: “Only if we understand, will we care. Only if we care, will we help.”

Goodall’s message of hope defined her activism; traveling 300 days a year, she authored 25+ books, including The Book of Hope (2022), and hosted the Hopecast podcast, urging action against despair. As a vegan advocate, she supported initiatives like the Trillion Trees campaign and Trees for Jane, emphasizing resilience in nature and youth. In 2017, she established the Jane Goodall Legacy Foundation to sustain her programs, ensuring Gombe research and global efforts endure.

Tributes poured in upon her death: President Joe Biden awarded her the Presidential Medal of Freedom in 2025, calling her a mobilizer of global movements. David Attenborough hailed her as transforming chimpanzee understanding, while Prince William and Greenpeace mourned a conservation giant. The UN family grieved a tireless planet protector. Her legacy—humanizing animals, empowering communities, and instilling hope—continues through JGI, Roots & Shoots, and inspired generations, proving individual action sparks change.
