The Spring Hill Chronicles are a record of Jacques Vallee’s private study into unexplained phenomena between 1990 and the end of the millennium, during which he was traveling around the globe pursuing his professional work as a high-technology investor.

This fourth volume of Forbidden Science takes the reader behind the scenes: to the board room of the National Institute of Discovery Science; to meetings with congressmen and intelligence officials; and to the closed sessions of the Rockefeller Initiative. Vallee’s field study of UFO close encounters in the USSR in 1990 and the Haravilliers mystery in France at the end of the decade—two major episodes, still unexplained today—serve as bookends between which he studied dozens of remarkable events yielding veridical data analyzed in the laboratory. This was a period during which scientists were finally able to study UFOs with adequate resources, producing results that were at once challenging and puzzling.

About the Author:

JACQUES VALLEE holds a master’s degree in astrophysics and a Ph.D. in computer science. The subject of UFOs first attracted his attention as an astronomer in Paris. He subsequently became a close associate of Project Blue Book’s J. Allen Hynek and has written several books on the UFO enigma. He is presently a venture capitalist living in San Francisco.

What they're saying:

"Brilliant and informative: Science is finally catching up with Vallee's speculations, laid bare in Forbidden Science where this venture/adventure is documented, inextricably linked to discovery. Volume IV encompasses a history of engagement with the phenomenon that attests to new forms of scientific methods that Vallee was only able to speculate about in the '70s and 80s, but that we now begin to create." — Dr. Diana Pasulka, Chair, Department of Philosophy and Religion, University of North Carolina, Wilmington

"This is the fourth volume of a mammoth (2000 pages and counting) series released over the past 25 years which form chronological diary entries covering a decade in the life of one of the most important scientists in the field of anomaly research....Today he is one of the last survivors of the early years of UFO research...Vallee's engaging style of observation is a big help in allowing the book to flow despite its length. There is a curious fascination in following his journey through a decade and coming upon moments when he hears of a major event or meets another as reader you get what really happened day by day from a true giant of the UFO field. — Jenny Randles, Magonia

"The rich tapestry of this chronicle reveals background material on a vast array of topics. What is guaranteed is that you will learn things about subjects you never knew existed...This is a veritable Who’s Who in the study of UFOs and other phenomena....There are interesting and probingly insightful commentaries....For any serious researcher or student of UFO phenomena, Jacques Vallée’s Forbidden Science 4 is not just suggested, rather it is mandatory reading." — John Alexander, Journal of Scientific Exploration

"As a unique original thinker, and the smartest guy in most rooms where ufologists congregate, Vallee is formidable...His contributions to UFO study equal anybody's in their scope and insight...Forbidden Science 4 is a commendably open portrayal of the man, his strengths and flaws in full, brave view. If you care about this subject, you had better read it." — Jerome Clark, Fortean Times
