Donald Menzel

1952–1976

Harvard astronomer and the era's most prominent public UFO skeptic, having authored multiple books debunking sighting reports. Named in the disputed 1984 MJ-12 documents as an alleged member ("MJ-10") - an irony Stanton Friedman highlighted after FOIA research revealed Menzel privately held a Top Secret Ultra clearance and extensive undisclosed ties to the NSA.
