Famously dubbed as the woman who redefined man, Jane Goodall is an English primatologist, anthropologist, and animal rights activist. She is best known for her 60-year study of behavior of chimpanzees in Tanzania. She was fascinated by animal behavior from her early years and dreamt of traveling to Africa to observe them in their natural habitat. Her passion for animals led her to the ‘Gombe Stream National Park’ in Tanzania. Chimpanzees were considered the second-most intelligent primate by her mentor and anthropologist Louis Leakey. Thus, she began her research by observing them on a daily basis. Her observation of chimpanzees challenged many long-term beliefs, such as chimpanzees are vegetarians. A previous belief that “man is the only toolmaker in all of the species that inhabit the earth” was discarded by her studies. This was considered a significant milestone in the course of scientific history of evolution. She also received many awards and accolades for her activism on creating a better society for animals. She wrote several books to encourage people to treat animals with kindness and love. She spends about 300 days a year traveling, lecturing, and raising funds for her institute in order to preserve wildlife. She was named a 'UN Messenger of Peace' in April 2002.
