Renowned for her chimpanzee research and environmental advocacy, Jane Goodall died on Wednesday at age 91 of natural causes, the Jane Goodall Institute announced on its Instagram page.
She was in California ahead of a planned speaking engagement in Los Angeles, according to her institute.
"Dr. Goodall’s discoveries as an ethologist revolutionized science, and she was a tireless advocate for the protection and restoration of our natural world," the Jane Goodall Institute said.
"Young Jane immersed herself in books about wild animals and dreamed of a life alongside African wildlife like Tarzan and Dr. Dolittle. At the young age of 23, after having spent the past few years as a waitress and secretary, she finally found a way to make her dream a reality," according to her official biography.
Goodall's studies of wild chimps began in 1960 when she visited the shores of Tanzania with her mother, Vanne. Amid her studies, she observed that chimpanzees utilized tools and exhibited other social traits that were previously thought to be unique to humans.
Once in Tanzania, she took what was considered an "unorthodox approach" toward studying wildlife. She immersed herself with chimps, gaining their trust and becoming a companion to chimpanzees. She gave chimps human-like names and came to understand their personalities and behaviors.
Following her initial studies in Tanzania, she became one of the first eight people to be admitted to Cambridge University's Ph.D. program without an undergraduate degree. She earned her doctorate in ethology in 1966, but continued her research at Gombe National Park.
She launched the Jane Goodall Institute in 1977, which has since expanded to have offices in 24 countries. These institutions continue ongoing research on chimpanzees and advocate for the protection of chimpanzees and their habitats.
Goodall continued sharing her love of chimps and her knowledge through multiple books and programs. Her most recent book, “The Book of Hope: A Survival Guide for Trying Times,” was published in 2021.
Even into her 90s, Goodall remained a vocal advocate for conservation. At the time of her death, she had several speaking engagements scheduled for the coming days.
Breaking story will be updated. Just last week, she was in New York for Climate Week, where she reportedly told audience members to "have courage" in taking on sustainability.
