Jane Goodall’s Cause of Death Revealed: Cardiac Arrest at 91

UPDATE: The cause of death for renowned primatologist Jane Goodall has been confirmed as cardiopulmonary arrest, according to a death certificate obtained by TMZ. Goodall, who passed away at the age of 91 earlier this month, also had epilepsy listed as a condition, though its role in her death remains unclear.

Goodall’s death was announced on October 1, 2025, by the Jane Goodall Institute, which revealed she was in California for a speaking tour at the time of her passing. The institute described her death as resulting from natural causes.

Cardiopulmonary arrest is a critical condition characterized by a sudden loss of heart function, leading to a rapid decline in organ function due to lack of oxygenated blood. According to the Cleveland Clinic, only about 1 in 10 people survive a cardiac arrest outside of a hospital, and about 1 in 4 survive when it occurs in a medical facility.

The news of Goodall’s death has generated an outpouring of tributes from those inspired by her groundbreaking work. Her legacy began in 1960 when she traveled to Tanzania at just 26 years old to study chimpanzees, forever changing the way the world understands not only primates but also the emotional and social complexities of all animals.

Goodall’s pioneering research and advocacy for wildlife conservation elevated her to global prominence. “What the chimps have taught me over the years is they’re so like us,” she stated in a 1997 interview with the Associated Press. Her ability to connect with both animals and people has left an indelible mark on environmentalism.

The Jane Goodall Institute has emphasized that her work will continue through the countless individuals she inspired. As tributes flood in, supporters pledge to uphold her mission of conservation and education, ensuring that her legacy will live on.

For those affected by her passing, the message is clear: Goodall’s influence will persist, and her teachings remain vital. As the world mourns this loss, her commitment to protecting the natural world will continue to resonate, urging a new generation to carry forth her vision.
