The conservationist lady Jane Doodall died at the age of 91

The conservationist Dame Jane Goodall, a advanced expert from Chimpanzees, died at the age of 91.

His observations helped to reveal how closely humans are linked to chimpanzees. She also worked tirelessly for conservation projects around the world

Dr. Goodall died of natural causes in California during a tour of the United States, according to a press release from the Jane Goodall Institute.

He said that his discoveries “revolutionized science” and that it was “a tireless defender of the protection and restoration of our natural world”.

The United Nations said that she had cried Dr. Goodall’s loss, saying that she “worked tirelessly for our planet and all its inhabitants, leaving an extraordinary heritage for humanity and nature”.

Greenpeace said that it was “a broken heart” by his death, calling him “one of the real giants of the conservation of our time”.

Its director co-executive in the United Kingdom, Will McCallum, said: “The heritage of Dr. Goodall is not only in science, but in the world movement, it has helped to provoke nature and to give hope for a better world.”

Naturalist Chris Packham told the BBC that he had counted it among his heroes, calling him “revolutionary” and “remarkable”.

“Having lost a hero at a time when we need everyone on the front line to fight against life on earth is a tragedy.”

Born in 1934 and raised in London, Dr. Goodall said she had become fascinated by animals after reading books like the history of Dr. Dolittle and Tarzan.

She met the main primatologist Professor Louis Leakey while staying on a friend’s farm in Kenya in mid-vingeta. Although she did not have any qualifications, Mr. Leakey saw her potential and helped organize her first research trip to the Jungles of Tanzania in 1960.

That year, she became the first person to record an animal using a tool – a large male chimpanzee, Who had named David Graybeard, leaving the termites from a mound with a stick.

Until then, we thought that only humans were smart enough to do so. His observations have challenged years of conventional scientific thinking and shaped The future of evolutionary science.

Her work was published in leading journals and, in 1965, she covered National Geographic, presenting the world to the emotional and social life of primates.

She revealed that animals form solid family ties and even engaged in war on the territory. She appeared in a television documentary told by Orson Welles, who saw her play and fight with baby chimpanzees.

His approach – associating so closely with the animals that she studied, appointing them and even qualifying them as “my friends” – was mocked by certain scientists, mainly male, at the time. She undertook a doctorate according to his conclusions, although he does not have a first cycle diploma or previous scientific training.

After her experiences in the field, she became a activist, working at free chimpanzees preserved in zoos or in captivity for medical research, and then urged action on climate change in the face of a general devastation of habitat.

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

Asked what kept her motivated late in life, she said: “People surely want a future for their children.”

Its Jane Goodall Institute, founded in 1977, strives to protect chimpanzees and supports projects aimed at benefiting animals and the environment.

Dr. Goodall was appointed lady in 2003 and received the American Liberty Presidential Medal in 2025.

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

Dr. Goodall worked until his death, interviewed on stage in New York a week ago. She was to speak again during a closed -looking event on October 3 in California.
