Overview
Jacques Fabrice Vallée (French: [ʒak fabʁis vale]; born September 24, 1939) is a French Internet pioneer, computer scientist, venture capitalist, author, ufologist and astronomer currently residing in San Francisco, California and Paris, France.
His scientific career began as a professional astronomer at the Paris Observatory. Vallée co-developed the first computerized map of Mars for NASA in 1963. He later worked on the network information center for the ARPANET, a precursor to the modern Internet, as a staff engineer of SRI International's Augmentation Research Center (ARC) under Douglas Engelbart.
Vallée is also an important figure in the study of unidentified flying objects (UFOs), and unidentified anomalous phenomena (UAPs). Vallée was first noted for his defense of the scientific legitimacy of the extraterrestrial hypothesis and later for promoting the interdimensional hypothesis.
Early life
Vallée was born in Pontoise, France in 1939. He completed his undergraduate degree in mathematics at the University of Paris in 1959 and received the equivalent of an MS in astrophysics from the University of Lille Nord de France in 1961. He began his professional life as an astronomer at the Paris Observatory in 1961. He was awarded the Jules Verne Prize for his first science fiction novel, Le Sub-espace (1961), published under the pseudonym of Jérôme Sériel.
Academic and business career
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. While at McDonald Observatory, he compiled NASA's first detailed informational map of Mars with de Vaucouleurs.
In 1963, Vallée relocated to Chicago, Illinois. He was initially employed as a systems analyst at nearby Northwestern University while continuing to pursue non-institutional ufological research with his mentor, J. Allen Hynek, the chair of the University's astronomy department. Professionally, he began to conduct early artificial intelligence research and received a PhD in industrial engineering and computer science from the institution in 1967. His doctoral advisor was Gilbert Krulee. 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. In 1970, Vallée became a consultant to Stanford applied physicist Peter A. Sturrock's Institute for Plasma Research. Upon learning that Vallée had written several books about UFOs, Sturrock felt a professional obligation to peruse Vallée's work, prompting his own research in the subject.
In 1971, Vallée left Stanford to join the Engelbart group as a senior research engineer. His tenure at ARC coincided with the group's immersion in Erhard Seminars Training and other social experiments, ultimately prompting his departure. While at the Institute for the Future as a senior research fellow from 1972 to 1976, he succeeded Paul Baran as principal investigator on the large National Science Foundation project for computer networking, which developed one of the first ARPANET conferencing systems, Planning Network (PLANET), predating instant messaging by many years. The technology was spun off into InfoMedia, a startup company founded by Vallée in 1976. Although the firm formed several international spinoffs and partnered with a variety of prominent firms and governmental organizations (including Lehman Brothers, Renault and NASA), it failed to attain long-term profitability.
Following its sale in 1983, Vallée entered the venture capital sphere as a partner at Sofinnova. From 1987 to 2010, he served as a general partner of several funds in Silicon Valley, most notably as the co-founder of the family of three Euro-America Ventures funds in North America and Europe. 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. 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.
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.
Paranormal research
According to Vallée, he sighted an unidentified flying object over his Pontoise home in May 1955. 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. The particular object was a retrograde satellite – that is, a satellite orbiting the Earth in the opposite direction to the Earth's rotation. At the time he observed this, there were no rockets powerful enough to launch such a satellite, so the team was quite excited as they assumed that the Earth's gravity had captured a natural satellite (asteroid). He claims that an unnamed superior came and erased the tape. These events contributed to Vallée's lifelong interest in the UFO phenomenon. Vallée began to correspond with Aimé Michel (who would become a key mentor and research collaborator) in 1958.
In the mid-1960s, like many other UFO researchers, Vallée initially attempted to validate the popular extraterrestrial hypothesis (or ETH).
However, by 1969, Vallée's conclusions had changed, and he publicly stated that the ETH was too narrow and ignored too much data. Vallée began exploring the commonalities between UFOs, cults, religious movements, demons, angels, ghosts, cryptid sightings, and psychic phenomena. His speculation about these potential links was first detailed in his third UFO book, Passport to Magonia: From Folklore to Flying Saucers.
As an alternative to the extraterrestrial visitation hypothesis, Vallée has suggested a multidimensional visitation hypothesis. This hypothesis represents an extension of the ETH where the alleged extraterrestrials could be potentially from anywhere. The entities could be multidimensional beyond space-time; thus they could coexist with humans, yet remain undetected.
Vallée's opposition to the popular ETH was not well received by prominent U.S. ufologists, hence he was viewed as something of an outcast. Indeed, Vallée refers to himself as a "heretic among heretics".
Archives of the Impossible
The Archives of the Impossible (AOTI) of Rice University at Houston, Texas is a special collection founded in 2014 by Jeffrey J. Kripal, a professor of religion. AOTI is based at the Woodson Research Center (WRC) and materials are housed in the Fondren Library. AOTI was initiated with a donation by Vallée of his collected lifetime research materials. Vallée initially asked Kripal in December 2014 if he could help locate a university archive to store his collections, due to worries about "potential loss or commercialization" of his research. After four years of negotiation, Vallée donated his collection to AOTI. Vallée formalized the accession process at Rice by holding a lecture of his research in 2018. In 2022, Wired reported that Vallée's collection in AOTI would include files on about 500 anomalous events that he investigated. Some Vallée materials in AOTI have embargoes until by his request, due to their "sensitive nature", according to the journal of the WLA. The Vallée release embargo extends to 2028-2031.
In popular culture
In 1979, Robert Emenegger and Alan Sandler updated their 1974 UFOs: Past, Present, and Future documentary with new 1979 footage narrated by Jacques Vallée. The updated version is entitled UFOs: It Has Begun.
Vallée served as the real-life model for Claude Lacombe, the researcher portrayed by François Truffaut in Steven Spielberg's 1977 film Close Encounters of the Third Kind. He also attempted to interest Spielberg in an alternative explanation for the phenomenon. In an interview on Conspire.com, Vallée said, "I argued with him that the subject was even more interesting if it wasn't extraterrestrials. If it was real, physical, but not ET. So he said, 'You're probably right, but that's not what the public is expecting — this is Hollywood and I want to give people something that's close to what they expect.'"
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. According to Robert Sheaffer this was a joke by the X-Files creator Chris Carter to name the characters after Vallee and Sheaffer. Sheaffer further states that "the M.P. who later arrested them [the characters] was Sgt. Hynek", a reference to ufologist J. Allen Hynek.
Personal life
Vallée was married to Janine Saley from 1960 until her death in 2010. They have two children, Olivier and Catherine.
