Excerpted from wikipedia: Jacques Fabrice Vallée (born September 24, 1939 in Pontoise, Val-d'Oise, France) is a venture capitalist, computer scientist, author, ufologist and former astronomer currently residing in San Francisco, California.
In mainstream science, Vallée is notable for co-developing the first computerized mapping of Mars for NASA and for his work at SRI International in creating ARPANET, a precursor to the modern Internet. Vallée is also an important figure in the study of unidentified flying objects (UFOs), first noted for a defense of the scientific legitimacy of the extraterrestrial hypothesis and later for promoting the interdimensional hypothesis.
