Alan Robert Rabinowitz was an American zoologist, conservationist, field biologist and the CEO of Panthera, a nonprofit conservation organization devoted to protecting the world's 37 wild cat species. Called the "Indiana Jones of Wildlife Protection" by Time, Rabinowitz has studied jaguars, clouded leopards, Asiatic leopards, tigers, Sumatran rhinos, bears, leopard cats, raccoons, and civets. Today, Rabinowitz’s work focused on conserving the world’s largest, most imperiled cats—tigers, lions, jaguars, and snow leopards—and their habitats.
