Ivan Marx

Ivan Lee Marx (March 31, 1921 - December 18, 1999) was an American nature photographer, professional woodsman and tracker, and Bigfoot researcher, noted for his co-discovery of the Bossburg Cripple tracks in 1969 (with René Dahinden and John Green), and his later claim to have filmed an injured crypto-hominid in 1970, footage of which was included in his 1976 documentary The Legend of Bigfoot.
