Jacques Fabrice Vallée (French: [ʒak fabʁis vale]; born September 24, 1939) is an Internet pioneer, computer scientist, venture capitalist, author, ufologist and astronomer currently residing in San Francisco, California and Paris, France.

[1] Vallée moved to the United States in 1962 and began working as a research associate in astronomy under Gérard de Vaucouleurs at the University of Texas at Austin.

Thereafter, he briefly worked for Royal Dutch Shell (in Paris) and the RCA Service Company (in Cherry Hill, New Jersey) as an engineer before joining the Stanford University Computer Center as manager of information systems in 1969.

As a private investor, he continues to serve as executive manager of Documatica Financial, a San Francisco boutique focused on early-stage healthcare and technology startups.

[3] Among the companies for which he spearheaded early-stage financings, fourteen achieved initial public offerings, including Electronics for Imaging, Accuray (developers of the "CyberKnife" for cancer surgery), NeoPhotonics (developers of nanotechnology for optical networks), Mercury Interactive, P-Com, Isocor, Regeneration Technologies, Harmonic Lightwaves, Ixys, Integrated Packaging, E.Piphany, Sangstat Medical, Com21 and Synaptic Pharmaceuticals (which specialized in neurotransmitter biology).

Other companies financed by Vallée (most notably HandyLab, which produced an instrument recognized as being "transformative for oncology") were successfully acquired by Becton-Dickinson, Intel, Lucent, AOL, Cisco, Wilson Greatbatch and Intuitive Surgical.

[3] He has also served on the National Advisory Committee of the University of Michigan College of Engineering and authored four books on high technology, including Computer Message Systems, Electronic Meetings, The Network Revolution, and The Heart of the Internet.

Six years later in 1961, while working on the staff of the French Space Committee, Vallée claims to have witnessed the destruction of the tracking tapes of an unknown object orbiting the Earth.

Vallée began exploring the commonalities between UFOs, cults, religious movements, demons, angels, ghosts, cryptid sightings, and psychic phenomena.

Vallée's opposition to the ETH theory is summarised in his paper, "Five Arguments Against the Extraterrestrial Origin of Unidentified Flying Objects", Journal of Scientific Exploration, 1990: Scientific opinion has generally followed public opinion in the belief that unidentified flying objects either do not exist (the "natural phenomena hypothesis") or, if they do, must represent evidence of a visitation by some advanced race of space travellers (the extraterrestrial hypothesis or "ETH").

On the contrary, the accumulated data base exhibits several patterns tending to indicate that UFOs are real, represent a previously unrecognized phenomenon, and that the facts do not support the common concept of "space visitors".

[5][6][7] Via professional association with SRI and independent friendships with Harold E. Puthoff and Central Intelligence Agency analyst Kit Green (who obtained a temporary security clearance for him in 1974), Vallée was intermittently consulted on classified remote viewing research (including the Stargate Project) throughout the 1970s and 1980s.

During the early SRI experiments (led by Puthoff and Russell Targ in conjunction with Green as CIA contract monitor), he became acquainted with Uri Geller, Edgar Mitchell, Charles Musès, Andrija Puharich, Jack Sarfatti, Arthur M. Young, Edwin C. May, Pat Price and Ingo Swann.

'"[9] Episode "Jose Chung's From Outer Space" of X-Files which aired on April 12, 1996, had fake alien pilots named Jacques Sheaffer and Robert Vallee.
