J. Allen Hynek
The "professor’s apparent transformation from skeptic to UFO proponent was not quite the conversion event that it appeared on the surface. Since his teens Hynek had been an enthusiastic though closeted student of the occult. The French-born Jacques Vallee, a computer scientist and UFO author, was one of the few persons who knew Hynek’s secret. Hynek once told Vallee that he had become an astronomer in order to discover “the very limitations of science, the places where it broke down, the phenomena it didn’t explain” (Vallee 1996, 232). Nonetheless, the scientist’s public U-turn gave a big boost to the UFO movement, lending it a measure of credibility, and made Hynek into a celebrity as the nation’s “foremost expert on flying saucers” (O’Toole 1966). For two decades people could point to Hynek and say, “He’s a trained scientist, an astronomer no less: if even he believes in this UFO stuff then there must be something to it.”...
"Maybe astronomy textbooks didn’t give him the answers he wanted, and so, as a bookish teenager, Hynek began to study what he called “esoteric subjects.” After reading widely in the occult, he developed a particular fondness for the writings of the Rosicrucian secret societies, with their tantalizing promises of hidden ancient knowledge, and those of the so-called hermetic philosophers, especially Rudolf Steiner. The high schooler spent over $100—roughly $1,300 in today’s dollars—to purchase the Canadian mystic Manly Hall’s massive, richly illustrated tome An Encyclopedic Outline of Masonic, Hermetic, Qabbalistic and Rosicrucian Symbolical Philosophy: Being an Interpretation of the Secret Teachings Concealed within the Rituals, Allegories and Mysteries of All Ages, better known simply as The Secret Teachings of All Ages. “All my student friends thought I was crazy: why didn’t I buy a motorcycle instead, as they all did,” Hynek later told Jacques Vallee (Vallee 2010, 64–65)...
"Hynek’s true views on UFOs were still unknown to the public when the astronomer, now teaching at Northwestern University, first met Jacques Vallee in the fall of 1963. Taking a job as a computer programmer at Northwestern, Vallee became a close friend of Hynek and soon they formed a UFO discussion group: The astronomer would eventually nickname this group “the Invisible College” (Vallee 1996, 270)—a term first used by the Rosicrucians in the early 1600s.
