Henri Lhote

Henri Lhote (16 March 1903 – 26 March 1991) was a French explorer, ethnographer, and discoverer of prehistoric cave art. He is credited with the discovery of an assembly of 800 or more works of primitive art in a remote region of Algeria on the edge of the Sahara desert. He was aided by the local Tuareg guide . Lhote came to believe the paintings testified to ancient contact with extraterrestrial beings and is considered one of the early proponents of paleocontact. Provided by Wikipedia
