(Hoaxer) Ivan Marx
Ivan Marx (b. ???? d. 1999) was a well-known bigfoot researcher and film-maker who made several allegedly hoaxed films of bigfoot, most of which were gathered into 3 films, The Legend of Bigfoot (1976), In The Shadow of Bigfoot (1981) and Bigfoot Alive And Well In '82 (early or mid-'80's).
Many bigfoot Researchers allege that Marx's films are nothing more than hoaxes, and that Marx's wife Peggy was in the gorilla suits filmed by Marx. Marx was involved in the Bossburg, Washington Cripple Foot track finds of November 1969, and in October 1970, claimed to have captured film footage of the crippled bigfoot, although he turned down an offer of $25,000 for the footage if he could confirm its authenticity.
Marx was a mentor to controversial researcher Tom Biscardi.
