Conservative Dam Jane Dowell died at the age of 91

Conservative Dam Jane Gudol, a leading expert in chimpanzees, died at the age of 91.

Her observations have helped to reveal how many people related to chimpanzees. It also works tirelessly for conservation projects worldwide

Dr. Gudol died of natural reasons while in California at a talking tour of the United States, according to a statement by Jane Gudol’s Institute.

It states that her discoveries “revolutionized science” and that she is “a tireless defender of the protection and restoration of our natural world.”

The United Nations organization said it complained to the loss of Dr. Gudol, saying that “it works tirelessly for our planet and all its inhabitants, leaving an exceptional heritage to humanity and nature.”

Greenpeace said it was “broken from the heart” by her death, calling her “one of the real giants to protect our time.”

His co-executive director in the UK, Will McCalum, said: “Dr. Gudol’s heritage is not only in science, but also in the global movement, she helped to defend herself to protect nature and to give hope for a better world.”

Naturalist Chris again told the BBC that he counted her among her characters, calling her “revolutionary” and “remarkable.”

“Let’s lose a hero at a time when we need them all on the front line that fights for life on Earth is a tragedy.”

Born in 1934 and raised in London, Dr. Gudol says she was fascinated by animals after reading books such as the history of D -Dolittle and Tarzan.

She met with leading primaler Prof. Luis Licky while staying at a friend’s farm in Kenya In the mid -twenties. Although he had no qualification, D -H Licky saw his potential and helped organize his first research trip to the Jungles in Tanzania in 1960.

In the same year she became the first person to record an animal witness using an instrument – a large male chimpanzee, When she was named David Grabert, digging termites from a mound with a stick.

Until then, it was thought that only people were intelligent enough to do so. Her observations challenge years of conventional scientific thinking and shaped The future of evolutionary science.

Her work was published in leading magazines, and in 1965 she made the front cover of National Geographic by introducing the world into the emotional and social life of primates.

She revealed that animals form strong family ties and even participate in war over the territory. She has starred in a television documentary told by Orson Wales, who saw her play and fight baby chimpanzees.

Her approach – associated so closely with the animals she studied, named them and even called them as “my friends” – was ridiculed by some, mostly men, scientists at the time. She took a PhD based on her discoveries, although she had no bachelor’s degree or some prior scientific training.

After her experience in the field, she became an activist, works to release chimpanzees, held in zoos or in captivity for medical research, and later called for the actions for climate change in the face of the widespread devastation of the habitat.

She told the BBC in 2024: “We are in the middle of the sixth big disappearance … The more we can do to restore nature and protect the existing forests, the better.”

Asked what keeps her motivated late in her life, she said, “Certainly people want a future for their children.”

Her Jane Gudol Institute, founded in 1977, works to protect chimpanzees and support projects aimed at the benefit of animals and the environment.

D -R Gudol was appointed lady in 2003 and received the US presidential medal in 2025.

She was known for traveling constantly for her work, telling the Times in 2022 that she had not slept in the same bed for more than three weeks since 1986.

Dr. Gudol worked exactly until his death, interviewed on stage in New York a week ago. She had to talk again at a sold out on October 3 in California.
