James McDonald Papers

About of the person:

This is the personal papers of James E. McDonald (1920–1971), preserved as a manuscript collection by the University of Arizona Libraries Special Collections. McDonald was an atmospheric physicist and professor of meteorology at the University of Arizona (Associate Director of the Institute of Atmospheric Physics, 1954–1956; professor thereafter until his death). His primary scientific work concerned cloud physics, weather modification, and micrometeorology. From the late 1950s through 1971 he became one of the most prominent academic scientists advocating serious scientific study of UFOs. He interviewed hundreds of witnesses, reinvestigated cases (including many Project Blue Book files), criticized the Air Force’s handling of the subject and the 1969 Condon Report, testified before Congress in 1968, and publicly argued that the best unexplained cases were consistent with the extraterrestrial hypothesis (instrumented craft on information-gathering missions). The papers document both his mainstream scientific career and this intensive parallel UFO research activity.

Description of the archive:

The James E. McDonald papers constitute one of the most important individual scientific archives of UFO/UAP research from the classic era. The core consists of correspondence (1958–1971) with government and military officials, other scientists, and UFO researchers; detailed case files and investigations (primarily 1945–1970) covering sightings by military pilots, radar operators, air traffic controllers, law enforcement, scientists, and civilians in the United States, Canada, Australia, and New Zealand; photocopies of roughly 580 Project Blue Book reports (many radar-visual or pilot cases); four handwritten journals chronicling investigative activity; papers, talks, and monographs presented at scientific conferences and elsewhere; research notes from his 1967 Australia/New Zealand trip; materials related to the Condon Committee study; photographic materials; and more than 80 audio recordings of interviews, conversations, and talks.

As a data archive, the collection preserves primary source material generated by a credentialed atmospheric physicist who systematically examined official files, conducted field interviews, and documented both the cases themselves and the institutional responses of the Air Force and scientific community. It is especially strong on radar-visual cases, pilot reports, and the scientific critique of Project Blue Book and the Condon Report. The holdings support historical research into mid-20th-century official and scientific engagement with the UFO phenomenon and remain a key reference for scholars examining the evidentiary record of that period.
