Barack Obama, Prince William and Tanzanian president among many to mark death of primatologist at age of 91
Word leaders, friends and former colleagues have been paying tribute to the primatologist Jane Goodall, who died in California on Wednesday aged 91.
Goodall devoted her life to studying chimpanzees and other great apes, and became a global champion for primates and for conservation, helping to challenge the idea that the primates were vegetarian and that only humans could use tools. She died in her sleep from natural causes in Los Angeles while on a speaking tour, according to her institute, leading to an outpouring of dedications from around the world.
