A marine mammal scientist with a gift for clear, practical writing, this author helped bring whales, dolphins, and porpoises closer to both researchers and general readers. His books and field guides reflect decades of hands-on work studying cetaceans around the world.

J. Stephen Leatherwood was a marine mammal researcher and writer best known for books and field guides on whales, dolphins, and porpoises. Reliable sources available here describe him as widely known for marine mammal research and for publishing extensively on cetaceans.
He earned a Ph.D. from Texas A&M University and worked as a senior research biologist at the Hubbs Marine Research Institute. Later, he was associated with the Ocean Park Conservation Foundation in Hong Kong and served as a representative of the Cetacean Specialist Group within the International Union for Conservation of Nature.
Leatherwood also contributed practical reference works for observing and identifying marine mammals in the field, including publications connected to the Gulf of Mexico. He died in 1997, but his writing remains a useful bridge between scientific study and the wonder of encountering these animals in the wild.
