Marlin Perkins swam with sea lions, hogtied alligators and bore the harsh effects of an Indian elephant’s tusk, all to teach us about the world of animals. Perkins, a former director of the St. Louis Zoo, was famous three decades ago on a national television show called "Mutual of Omaha’s Wild Kingdom." He was St. Louis Zoo director from April 1962 until this week in 1970, but stayed as director emeritus. He hosted "Wild Kingdom" from 1962 to 1985.
