Aerial Phenomena Research Organization (APRO)

Founded in January 1952 in Sturgeon Bay, Wisconsin, "to conduct investigations and research into the phenomenon of unidentified flying objects (UFOs) and to find a scientifically acceptable solution to this phenomenon." Led by Jim Lorenzen and his wife, Coral Lorenzen, who authored several popular UFO books, APRO emerged as one of the most outstanding UFO investigation organizations. Through the 1950s the Lorenzens and APRO moved successively to Los Angeles (1954), Alamogordo, New Mexico (1954), and Tucson, Arizona (1960). Beginning as an association of flying saucer clubs that collected accounts of UFOs and commented upon them in the APRO Bulletin, APRO grew into a substantial research organization. It was distinguished from the National Investigations Committee on Aerial Phenomena (NICAP), the other main UFO research organization of the 1950s, by its coolness to the idea of a government cover-up of UFO data and its interest in sightings of humanoid-like creatures associated with the UFOs.

APRO membership peaked in 1967 with 1,500 members. Then in 1969 it suffered two disasters. First, the University of Colorado report of its study of UFOs, popularly known as the Condon Report, struck Ufology (the study of UFOs) a significant blow with the conclusion that nothing was likely to be achieved by further study. As a result, the Air Force dropped its semipublic data collection effort, Project Blue Book. Then APRO suffered a major schism when Walt Andrus, who led a regional office in Illinois, broke away and founded the Midwest UFO Network (now the Mutual UFO Network). Membership began a decline from which APRO never recovered. Jim Lorenzen died in 1986, and Coral followed two years later. The board voted to disband the organization shortly thereafter.
