Bobby Ray Inman
The admiral who ran the NSA from 1977 to 1981 and was the first NSA director to try, in public, to rein in academic cryptography.
Inman took over just as Diffie, Hellman, Rivest, Shamir and Adleman were publishing what the NSA had until then regarded as its own private field. In 1978 secrecy orders were slapped on cryptography patent applications, and in 1979 Inman gave a rare public speech warning that open research was harming national security and hinting that legislation might be needed.
What came out of it instead was a compromise: a study group under the American Council on Education proposed in 1981 that researchers voluntarily submit crypto papers to the NSA for review before publication. Some did; most stopped bothering within a few years. Inman went on to become deputy director of the CIA. In 1994 he withdrew his nomination as Secretary of Defense at a press conference so strange that it is mostly what people remember.
