Rabinowitz is director of the Science and Exploration Program at the Wildlife Conservation Society, based at the Bronx Zoo in New York. In 1985, his research in Belize resulted in the world's first jaguar sanctuary. Since then, he has spearheaded the preservation of vast tracts of wilderness land around the globe. The survival of the Jaguar is now in jeopardy. His work to save nature's largest cat is featured in the new National Geographic special In Search of the Jaguar (premiering on PBS, Wednesday, Nov. 26, at 8 p.m.). Rabinowitz is the author of three books: Jaguar, Chasing the Dragon's Tale and Beyond the Last Village. Two years ago Rabinowitz was diagnosed with a rare form of leukemia.
