Donald H. Menzel.
disputedsource_actorMajestic 12 & Disinfo
Harvard astronomer and famous public UFO debunker named as an MJ-12 member; real person with documented classified NSA/CIA consulting ties.
Menzel's listing as an MJ-12 member is paradoxical because he was a prominent public UFO debunker. Friedman's 1986 archival research established Menzel had genuine, long-standing classified work for the NSA and a TOP SECRET clearance, unknown even to his wife. The literal 'double life' (public scientist + classified consultant) is documented; the conspiratorial inference that this proves he hid alien craft rests on the disputed MJ-12 papers.
