Donald Howard Menzel (April 11, 1901 – December 14, 1976) — American astronomer; one of the first US theoretical astrophysicists. At Harvard from 1932; acting director (1952) then director (1954–1966) of the Harvard College Observatory. Notable solar-physics and spectroscopy work.
UFO debunking
- The leading scientific UFO skeptic of the 1950s–60s. Books: Flying Saucers (1953), The World of Flying Saucers (1963, w/ Lyle G. Boyd), The UFO Enigma (1977, w/ Ernest H. Taves). Thesis: all UFO reports are misidentifications of prosaic phenomena (stars, planes, balloons, atmospheric optics).
- Served on the CIA-organized Robertson Panel (1953), which recommended an official UFO-debunking program.
- Submitted a paper to the 1968 House Symposium (did not testify in person).
- James McDonald publicly judged Menzel’s meteorological-optics explanations “very far removed from the well-known principles and quantitative aspects of meteorological optics.”
Intelligence career
- WWII: U.S. Navy lieutenant commander, headed an intelligence division (cryptography/codebreaking).
- A documented “double life” (per Stanton Friedman’s The Secret Life of Donald H. Menzel): a leading cryptographer with high security clearances who met regularly with NSA, CIA, and other intelligence leadership.
- Named as a member in the forged MJ-12 documents (1984) — a forgery; likely a hoaxers’ in-joke trading on his real intelligence ties.
