Bernard Heuvelmans

Bernard Heuvelmans (10 October 1916 – 22 August 2001) was a Belgian-French scientist, explorer, researcher, and writer probably best known, along with Scottish-American biologist Ivan T. Sanderson, as a founding figure in the pseudoscience and subculture of cryptozoology. His 1958 book ''On the Track of Unknown Animals'' (originally published in French in 1955 as ''Sur la Piste des Bêtes Ignorées'') is often regarded as one of the most influential cryptozoology texts.
