Josef Allen Hynek (1 May 1910 – 27 April 1986) was an American astronomer who served for more than two decades as the U.S. Air Force's scientific consultant on UFOs, and later became the most prominent scientist to argue that the subject deserved serious study. He created the "close encounter" classification and founded the Center for UFO Studies.[1]
Early life and astronomy career

Hynek was born in Chicago to Czech parents. He earned a bachelor's degree from the University of Chicago in 1931 and a PhD in astrophysics from the university's Yerkes Observatory in 1935, and joined the physics and astronomy department of Ohio State University in 1936. During World War II he worked at the Johns Hopkins Applied Physics Laboratory on the Navy's radio proximity fuze.[1] In 1956 he joined the Smithsonian Astrophysical Observatory to direct the tracking of artificial satellites for the International Geophysical Year, including the volunteer Operation Moonwatch. From 1960 until 1978 he chaired the astronomy department at Northwestern University.[1]
Air Force consultant
Hynek was hired as a consultant to Project Sign in 1948 and stayed on through Project Grudge and Project Blue Book until 1969. He began as a skeptic, reportedly describing the subject as "utterly ridiculous", and explained many reports as astronomical objects. In 1953 he was an associate member of the CIA's Robertson Panel, whose debunking recommendations he later said had damaged the field.[1]
Over time the quality of some witnesses, including military pilots, and the Air Force's rigid attitude changed his mind. In March 1966 he suggested that some sightings in Michigan might be explained by "swamp gas", a remark that was widely ridiculed and drew national attention; he said it was meant to apply to only some of the reports.[1][2] In 1968 he told a congressional symposium that the Air Force's efforts were "totally inadequate".[1][3]
The UFO Experience and close encounters
In The UFO Experience: A Scientific Inquiry (1972), Hynek set out a classification of sightings. Distant reports were divided into nocturnal lights, daylight discs and radar-visual cases; close-range reports became "close encounters" of the first kind (a close sighting), second kind (physical effects) and third kind (sightings of beings).[1] The scheme became widely known through Steven Spielberg's 1977 film Close Encounters of the Third Kind, on which Hynek was a consultant and in which he made a brief appearance.[1]
Center for UFO Studies

In 1973 Hynek founded the Center for UFO Studies (CUFOS) to encourage scientific research. He became increasingly doubtful of the extraterrestrial explanation and, at a 1973 MUFON symposium and later, discussed alternatives, including the idea that UFOs might be extradimensional. In 1978 he, Jacques Vallée and French engineer Claude Poher addressed a United Nations committee, calling for an international body to study UFOs.[1] His books included The Edge of Reality (1975, with Vallée), The Hynek UFO Report (1977) and Night Siege (1987, with Philip Imbrogno and Bob Pratt), about the Hudson Valley sightings.[1]
Controversy and legacy

Skeptics such as Philip Klass and Robert Sheaffer criticised his judgement, and he initially endorsed photographs from a 1967 case that later proved to be a hoax. Historian John Franch has argued that Hynek's early skepticism was partly a public stance and that he had long been interested in unconventional ideas.[1][4] Hynek died of a brain tumour in Scottsdale, Arizona, on 27 April 1986. His papers are held at Northwestern University, and the History Channel drama Project Blue Book (2019–2020) was loosely based on his work. His son Joel Hynek became an Academy Award-winning visual effects supervisor.[1][5]
