John A. Keel

John Alva Keel, born Alva John Kiehle, was a noted American woo-ologist. He was the author of several works of fiction; however Jadoo, published in 1957, was the last of these to be honestly labeled as such. His later inventions, such as The Mothman Prophecies, are marketed as "true stories". In the mid-1960s he, along with Gray Barker, was one of the primary popularizers of the original men in black stories.

He was also a prominent UFO researcher throughout the 60s and one of the more prominent ones to reject an extraterrestrial explanation, preferring a more spiritual or psychic explanations. One of his theories was that UFOs were due to an advanced (possibly non-human) civilization that wasn't visiting Earth, but was in fact from Earth.
