Isle Royale National ParkApril 3, 1904: Iron Eyes Cody is born in Kaplan, Louisiana. A Hollywood bit player who played Native American roles for years, Cody was cast in a 1971 ad where he canoes down a stream.  Polluting factories come into view, as a passing motorist hurls a bag of trash at his Cody’s feet.   A lone tear streams down Cody’s cheek.   But alas, Iron Eyes Cody’s real name was Espera di Corti, and he was a full-blooded Italian.
