{"type":"people","slug":"david-marler","title":"David Marler","url":"https://disclosdex.com/people/david-marler","description":"U.S.-based UFO historian whose triangle-case research and archive leadership anchor a major civilian UAP records center","date":"1970-01-01T00:00:01.990Z","tags":["Historian"],"updated":"2026-05-18T13:35:34.000Z","disclosureRating":5,"connectionCount":7,"content":{"markdown":"David Marler is a U.S.-based UFO historian, author, former [MUFON](/organizations/mufon) Illinois state director, [CUFOS](/organizations/cufos) board archivist, and National UFO Historical Records Center executive director whose public record centers on triangular UFO reports and the preservation of civilian UAP case files.[^1][^2]\n\n## MUFON Investigator and CUFOS Archivist\n\nNUFOHRC's team profile and CUFOS's board profile identify Marler as joining the Mutual UFO Network in 1990, later serving as a field investigator, state section director, and Illinois state director.[^1][^2] CUFOS identifies him as its board archivist and lists a Bachelor of Science in psychology from Southern Illinois University Edwardsville, hypnotherapy certification, sleep-disorder work, medical-equipment industry experience, and hospital administration in New Mexico as part of his background.[^2]\n\n## From Piedmont Stories to Triangle Cases\n\nRachel Whitt reported in a May 15, 2017 article for the University of New Mexico Newsroom that Marler first heard family stories in 1973 about sightings near Piedmont, Missouri, where his father knew witnesses to a major local event.[^3] Whitt also reported that his later MUFON work in Illinois brought him into police-witness reports of a triangular object near Scott Air Force Base, an episode covered in the site's [Illinois Police Officers Sighting](/events/2000-illinois-police-officers-sighting) entry, which Marler compared with descriptions from the [Belgian UFO wave](/events/1989-1990-belgian-ufo-wave).[^3][^4] Triangular reports then became his long-running research focus.[^3]\n\n## The Triangle-Case Argument\n\nHis 2013 book, *Triangular UFOs: An Estimate of the Situation*, presents a book-length analysis built from hundreds of reports, newspaper archives, military records, UFO periodicals, and witness interviews.[^3][^4] CUFOS's \"Triangular UFOs\" page summarizes Marler's primary and secondary characteristics for the reports, including recurring descriptions of very large objects, slow and low-altitude movement, hovering, silence, rapid acceleration, and lights at the corners of the triangle.[^4]\n\n## Evidence Threshold\n\nIn Santa Fe Magazine's interview with Marc Barasch, Warren Langford, Diego Diaz, and Marler, Marler emphasized contemporaneous investigator notes and original files as stronger than later retellings, and said the standard for a nonhuman or non-Earth conclusion would have to be physical evidence that could not be explained as terrestrial technology.[^5]\n\n## Building the National UFO Archive\n\nIn November 2020, Marler became curator of a large historical UFO case-file collection that CUFOS identifies as including [NICAP](/organizations/nicap) files, CUFOS files, and [J. Allen Hynek](/people/j-allen-hynek)'s original [Project Blue Book](/programs/project-blue-book) files.[^2] NUFOHRC's team profile identifies him as executive director and describes his accumulated library of UFO books, journals, magazines, newspapers, microfilms, recordings, and case files covering more than 75 years.[^1] A 2022 NUFOHRC press release introduced the organization as a U.S. nonprofit led by Marler with historians and archivists including Jan Aldrich, Rod Dyke, Barry Greenwood, Mark Rodeghier, and Rob Swiatek, with a mission to centralize and digitize historical UFO materials regardless of belief or non-belief.[^6]\n\nIn 2024, Rio Rancho Public Schools and NUFOHRC announced a memorandum of agreement to house and secure UFO-related historical documents, including declassified military reports, in school facilities for preservation and educational use.[^7] In Tommy Lopez's KOB report after the 2023 congressional UAP hearing, Marler called the hearing a change in the dialogue while also saying evidence was still required beyond statements and claims.[^8]\n\n## Conventional Explanations Remain in Play\n\nJohn B. Alexander's 2016 Journal of Scientific Exploration review of Marler's book and AARO's February 2024 historical report point to ordinary objects or phenomena, misidentification, cultural or media reinforcement, and broad category definitions as important limits on case interpretation.[^9][^10] Alexander also noted a basic definitional problem: \"UFO\" covers observations ranging from distant lights to large close-range objects, making any single explanation or statistical treatment difficult.[^9]\n\n## What the Record Does Not Prove\n\nMarler's archive work preserves civilian UFO records, while his triangle-case writing relies on case files, witness reports, and pattern comparison.[^1][^4][^6][^7] Preservation alone does not independently verify each underlying sighting, and large triangle reports remain vulnerable to prosaic explanations and broad category definitions.[^9][^10] Marler's public comments reserve nonhuman-origin conclusions for physical evidence beyond terrestrial explanation.[^5]\n\n## References\n\n[^1]: [National UFO Historical Records Center, \"Our Team: David Marler, Executive Director\"](https://nufohrc.org/team/)\n[^2]: [Center for UFO Studies, \"David Marler\"](https://cufos.org/about-us/cufos-board-consultants-and-friends/david-marler/)\n[^3]: [Rachel Whitt, \"Willard Lecture Series to address UFO research,\" University of New Mexico Newsroom, May 15, 2017](https://news.unm.edu/news/willard-lecture-series-to-address-ufo-research)\n[^4]: [Center for UFO Studies, \"Triangular UFOs\"](https://cufos.org/types-of-ufos/triangular-ufos/)\n[^5]: [Santa Fe Magazine, \"Why do They Like Us?,\" interview with Marc Barasch, David Marler, Warren Langford, and Diego Diaz](https://santafemagazine.co/article/why-do-they-like-us/)\n[^6]: [National UFO Historical Records Center, \"Introduction of the newly-established National UFO Historical Records Center,\" press release, November 18, 2022](https://podcastufo.com/wp-content/uploads/2022/11/PRESS-RELEASE-INTERNET.pdf)\n[^7]: [Rio Rancho Public Schools and National UFO Historical Records Center, \"Rio Rancho Public Schools and National UFO Historical Records Center Announce Groundbreaking Partnership,\" press release, June 25, 2024](https://www.kob.com/wp-content/uploads/2024/06/Rio-Rancho-Public-Schools-and-National-UFO-Historical-Records-Center-Announce-Groundbreaking-Partnership.pdf)\n[^8]: [Tommy Lopez, \"UFO researcher calls latest development 'watershed moment,'\" KOB](https://www.kob.com/new-mexico/ufo-researcher-calls-latest-development-watershed-moment/)\n[^9]: [John B.
