Author of the Foreword for Love in their Hearts, Dr. Jane Goodall (1934–2025) was a pioneering primatologist, conservationist, and author whose groundbreaking research on wild chimpanzees transformed our understanding of animal behavior and the relationship between humans and the natural world. To experience what made Jane so beloved, read Jane Goodall at 90. Edited by Marc Bekoff and his colleague Dr. Koen Margodt, this book celebrated Jane’s ninetieth birthday by collecting ninety original essays by people whose hearts were touched and lives transformed by Jane.
