A Belgian-French zoologist, often called the founder of cryptozoology. His name runs through several of the archive's strangest animal cases. Mid-December 1968, he arrived at a farm with Sanderson to see the Minnesota Iceman. For three days they studied the body through ice and glass, taking photographs and making sketches. Earlier accounts drew his attention too. He took the Valhalla sea serpent seen off Brazil in 1905 for a marine mammal, pointing to its dorsal fin and head. When a museum curator rejected van Herwaarden's 1923 sedapa account from Sumatra, Heuvelmans disputed the dismissal.
