Jacques Vallée, born September 24, 1939 in Pontoise, Val-d'Oise, France.

Jacques Vallée (French: [vale]; born September 24, 1939) is a notable ufologist who proposed that "extraterrestrials" have been on Earth all along and are possibly indigenous to this planet.

Professional careerEdit

Jacques Vallée began his professional career as an 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,[1] as a staff engineer of SRI International's Augmentation Research Center under Douglas Engelbart.[2]

In 1963, Vallée relocated to Chicago, Illinois. He worked as a systems analyst at nearby Northwestern University while continuing to pursue ufological research with his mentor, J. Allen Hynek, the chair of the University's astronomy department. During this period, he received a Ph.D. in industrial engineering and computer science from the institution in 1967.[2]

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.[3]


Jacques Vallée is an important figure in the study of unidentified flying objects (UFOs), first noted for his defense of the scientific legitimacy of the extraterrestrial hypothesis and later for promoting the interdimensional hypothesis.[2] Vallée proposed that there is a genuine UFO phenomenon, partly associated with a form of non-human consciousness that manipulates space and time. The phenomenon has been active throughout human history, and seems to masquerade in various forms to different cultures. In his opinion, the intelligence behind the phenomenon attempts social manipulation by using deception on the humans with whom they interact.

Vallée believes that the available evidence, when carefully analyzed, suggests an underlying plan for the deception of mankind by means of unknown, highly advanced methods. Vallée has stated that it is highly unlikely that governments actually conceal alien evidence. Rather, it is more likely that the manipulators want the humans to blame their governments. Vallée feels the entire subject of UFOs has been degraded by charlatans and science fiction. He has advocated for serious and scientific involvement of UFO research and debate, in an effort to reveal the true nature of the UFO phenomenon.[4]

Extraterrestrial hypothesisEdit

In May 1955, Jacques Vallée first sighted an unidentified flying object over his Pontoise home. Ten years later, Vallée initially attempted to validate the Extraterrestrial Hypothesis (ETH). UFO researcher Jerome Clark commented that Vallée's first two UFO books were among the most scientifically sophisticated defenses for ETH ever mounted.[5]

By 1969, Vallée's ETH conclusions evolved. He publicly stated that 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. Speculation about these potential links were first detailed in Vallée's third UFO book, “Passport to Magonia: From Folklore to Flying Saucers”.

Interdimensional hypothesisEdit

As an alternative to the extraterrestrial visitation hypothesis, Jacques Vallée has suggested a multidimensional visitation hypothesis. This idea proposes that entities could be from multidimensional parallel universes beyond space-time, and thus could coexist with humans, yet remain undetected.[6]

Vallée's abondonment of ETH was not well received by prominent U.S. ufologists, hence he was viewed as something of an outcast. Vallée has refered to himself as a "heretic among heretics".[7] Vallée's current stance on ETH is summarised in his paper, "Five Arguments Against the Extraterrestrial Origin of Unidentified Flying Objects", Journal of Scientific Exploration, 1990.

The AviaryEdit

Jacques Vallée has been associated with codename “parrot” of The Aviary,[8] a team of UFO disinformants[9] who have been active from 1980—2010. It is not certain what Vallée’s role was or if he has continued with them since the 1990s.
