J. Allen Hynek chaired the astronomy department at Northwestern University from 1960 to 1978 and served as the U.S. Air Force's primary scientific consultant on UFO reports through Project Blue Book until its 1969 closure.
In his 1972 book and earlier congressional testimony, Hynek stated that Project Blue Book had systematically applied mundane explanations to cases lacking supporting evidence and that a portion of reports remained unidentified after investigation.

Background
Josef Allen Hynek was born May 1, 1910, in Chicago, Illinois. He earned a B.S. in 1931 and a Ph.D. in astrophysics in 1935 from the University of Chicago. His early research focused on stellar spectra and spectroscopic binaries at Yerkes Observatory.
Hynek joined the faculty at Ohio State University in 1936. He served as Supervisor of Technical Reports at Johns Hopkins Applied Physics Laboratory from 1942 to 1946 on wartime projects. In 1948 the U.S. Air Force recruited him to evaluate astronomical explanations for flying saucer reports at Wright-Patterson Air Force Base.
Hynek continued as consultant through Project Sign, Project Grudge, and Project Blue Book. He reviewed thousands of sighting reports while maintaining his academic career. By the mid-1950s he had grown skeptical of the Air Force's approach to unexplained cases.
In 1960 Hynek moved to Northwestern University as chair of the astronomy department and director of the Dearborn Observatory. He testified before Congress in 1966 after the Michigan sightings, stating that the Air Force's swamp-gas explanation did not fit all reports and that some cases warranted further study.
Hynek's 1972 book The UFO Experience analyzed Blue Book data and criticized the program's emphasis on public reassurance over thorough investigation. He outlined six categories of reports, including close encounters of the first, second, and third kind, and argued for systematic scientific examination of the unexplained residue.
In 1973 Hynek founded the Center for UFO Studies to collect and analyze reports independently. He retired from Northwestern in 1978 to focus on the organization. He continued field investigations and public talks while maintaining that most cases had conventional explanations but a small percentage did not.
Hynek moved the Center for UFO Studies to Arizona in 1984 seeking support. He died of a brain tumor on April 27, 1986, at age 75 in Scottsdale, Arizona. His papers and case files remain archived at Northwestern University.
Legacy
J. Allen Hynek died on April 27, 1986. The Center for UFO Studies he founded in 1973 continues operations under the name J. Allen Hynek Center for UFO Studies.
His close-encounter classification system entered popular culture through the 1977 film Close Encounters of the Third Kind, on which he served as technical advisor. Project Blue Book case files he helped compile are held at the U.S. National Archives.
