For nearly two decades, Dian Fossey immersed herself in the study of mountain gorillas in Africa. She became known as a highly respected primatologist—a scientist who studies apes and other primates—and a fiercely devoted champion of their safety and preservation. Fossey had made powerful enemies because of her opposition to the gorilla-related tourism industry and her knowledge of animal trafficking among members of the government. In 1985, she was found murdered in her cabin in Rwanda. The case remains unsolved to this day, but her intense love for this endangered species helped create a legacy that survives in the work of others to this day.
