NATURE | The Gorilla King | Preview | PBSNATURE retraces the life of Titus, silverback leader, from birth to present reign, spanning a tumultuous period in the history of a species and a nation in "The Gorilla King." In 1974, renowned primatologist Dian Fossey introduced a young researcher named Kelly Stewart to a gorilla family Fossey was studying. Stewart, daughter of actor Jimmy Stewart, was the first to see a tiny new baby gorilla. She named him Titus, and her journal entry began the up-close observation of his life that researchers have continued to this day. Witness Titus's turbulent life story, from orphan to ruler and the challenge to his throne today. Part of the 26th season of the Peabody and Emmy award-winning series produced by Thirteen/WNET New York for PBS, “The Gorilla King” premieres Sunday, April 20, at 8 p.m. ET (check local listings).
