Jane Goodall Cause of Death Revealed

Dr. Jane Goodall, the world-renowned primatologist and chimpanzee expert, died earlier this month … and TMZ has learned the cause.

According to the death certificate … Goodall’s cause of death is listed as cardiopulmonary arrest — which is just another name for cardiac arrest, an incident where the heart simply stop beating.

Risk of cardiopulmonary arrest goes up as a person gets older … so, this cause of death isn’t totally surprising — and, it’s considered natural.

Jane also had epilepsy according to the death certificate … unclear if that played a factor at all in her passing.

As we previously reported … Jane passed away October 1 in California while on a speaking tour of the United States.

Jane was one of the world’s first female experts on primates, beginning her career by making a trip to Kenya to visit a friend in 1957 and connecting with paleoanthropologist and archaeologist Louis Leakey.

Dr. Goodall famously observed chimpanzees using tools … completely challenging the perceptions surrounding the animals.

She was 91 years old.
