Haakon_Chevalier

Haakon Maurice Chevalier (September 10, 1901 – July 4, 1985) was an American writer, translator, and professor of French literature at the University of California, Berkeley best known for his friendship with physicist J. Robert Oppenheimer, whom he met at Berkeley, California in 1937.
Oppenheimer's relationship with Chevalier, and Chevalier's relationship with a possible recruiter for Soviet intelligence, figured prominently in a 1954 hearing of the U.S. Atomic Energy Commission on Oppenheimer's security clearance. At that hearing, Oppenheimer's security clearance was revoked.
