Donald Rumsfeld
Donald Henry Rumsfeld (1932–2021) was an American politician and businessman who served as the 13th and 21st United States Secretary of Defense (1975–1977 under Ford; 2001–2006 under George W. Bush), and as White House Chief of Staff under President Gerald Ford (1974–1975). He is documented in UAP research primarily for a 1975 incident in which he personally denied J. Allen Hynek — the scientific adviser to Project Blue Book — access to information about any secret UAP programs that may have continued after Blue Book's closure.

The Hynek Denial (April 13, 1975)
On April 13, 1975, Hynek was told by Rumsfeld at the White House that he did not have a "need to know" whether a secret UAP study existed after Project Blue Book concluded in 1969. The use of the compartmentalized security phrase "need to know" — applied to the individual who had officially run the Air Force's public-facing UFO investigation for 17 years — was interpreted by Hynek as confirmation that classified successor programs existed to which he had never been given access.
This exchange is significant because it demonstrates that whatever UAP-related programs continued after Blue Book's closure were sufficiently compartmentalized that even the program's own chief scientific consultant was formally excluded from awareness of their existence.
Secretary of Defense
Rumsfeld later served as Secretary of Defense during the post-9/11 period, overseeing the invasion of Afghanistan and the Iraq War. He is also remembered for his cryptic "known unknowns" epistemological framework articulated at a 2002 press conference, which has been cited both critically and approvingly in discussions of intelligence analysis under uncertainty.
Rumsfeld separately selected Richard Haver as Special Assistant to the Secretary of Defense for Intelligence during his tenure at the Pentagon.
