The International Society of Cryptozoology (ISC) was a former professional organization founded in 1982 in Washington, D.C. It ceased to exist in 1998. It was founded to serve as a scholarly center for documenting and evaluating evidence of unverified animals; that is, animal species or forms which have been reported in some manner but which have not been scientifically proven to exist. The study of such animals is known as cryptozoology, and Cryptozoology was also the title of its journal. The President was Bernard Heuvelmans, and the Vice-President Roy Mackal. The Secretary was J. Richard Greenwell (died 2005), of the University of Arizona. Loren Coleman, John Willison Green, and several other prominent cryptozoologists were either Life Members, Honorary Members, or Board Members.
