For more than fifty years, explorer-naturalist George Schaller has been on a mission: to save the world’s great wild beasts and their environments. In this compelling biography, illustrated with Schaller’s own striking photographs, Pamela S. Turner examines the amazing life and groundbreaking work of the man International Wildlife calls “the world’s foremost field biologist.” Schaller’s landmark research revolutionalized field biology, demonstrating that it is possible to study dangerous animals in their own habitats: mountain gorillas in Central Africa, predatory tigers in India, mysterious snow leopards in the Himalayas, and many others. His insights about species and environment led him to successfully advocate for the protection of over 190,000 square miles of wilderness around the world – an area the size of Spain.
