Juanita Moody (née Morris; May 29, 1924 – February 17, 2015) was an American cryptographer, intelligence analyst and National Security Agency (NSA) executive.

[1][2] Moody was responsible for providing intelligence to the White House and Department of Defense during the Cuban Missile Crisis.

She remained interested in cryptanalysis, however, and joined a group that met outside of work to study a complex, unbroken German code system; as a result, she was assigned official code-related tasks.

[6] She planned to return to Western Carolina University at the end of the war, but her supervisor asked her to remain with the SIS.

[4] She was promoted to the National Security Agency's research and development department after the war, where Moody became involved in computational cryptanalysis and analytic machines.

This time it was to section chief of G-Group, which was responsible for overseeing NSA operations nearly everywhere except China and the Soviet Union.

[4][5] During the Cuban Missile Crisis in the fall of 1961, Moody was visited by Louis Tordella, the deputy director at NSA.

"[3] Lansdale was concerned that no one was providing the White House with that level of detail about an aggressive military buildup in Cuba, and he asked Moody to write up her findings.

"[3] After the discovery of nuclear weapons in Cuba in 1962, the mission at NSA shifted to assessing the war capabilities of the Soviet Union in real time or, as close to it as possible.

NSA director Gordon Blake established an around-the-clock team to provide the sigint summaries twice a day as well as immediate updates, as needed.

She once called United Nations ambassador Adlai Stevenson directly in the middle of the night at his hotel to apprise him of intelligence gathered a few hours earlier because State Department officials refused to put her through.

Moody became the focus of controversy in 1975 when she was called to testify in front of a Senate committee that was investigating abuses of power in federal intelligence agencies.
