Marlin Perkins

As the first host of the revolutionary and engaging nature program, "Mutual of Omaha’s Wild Kingdom," Marlin Perkins became a face and name familiar to many in the United States. And he was perfect for the job – boasting experience as the director of the Lincoln Park Zoo and the host of the zoo’s "Zoo Parade" TV show.

His time as host of "Wild Kingdom" encouraged him to work towards protecting endangered species, and in 1971 he co-founded the Wild Canid Survival and Research Center, now known as the Endangered Wolf Center.
