Dr. Jacques Fabrice Vallée is an Internet pioneer, computer scientist, venture capitalist, author, ufologist, and astronomer residing in San Francisco, California and Paris, France.

His scientific career began as a professional astronomer at the Paris Observatory, and he 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 Stanford Research Institute’s International Augmentation Research Center, under Douglas Engelbart.

Dr. Vallée is also an important figure in the study of unidentified flying objects (UFOs), and unidentified anomalous phenomenon (UAPs). Vallée was first noted for his defense of the scientific legitimacy of the extraterrestrial hypothesis and later for promoting the interdimensional hypothesis. He is the author of numerous books on the UFOs/UAP, most notably Passport to Magonia: From Folklore to Flying Saucers, The Invisible College: What A Group of Scientists Has Learned About the UFO Phenomenon, and, with J. Allen Hynek, The Edge of Reality: A Progress Report on Unidentified Flying Objects. Vallée also was awarded the Jules Verne Prize for the first of his four science fiction novels, Le Sub-espace, published in 1961 under the pseudonym of Jérôme Sériel
