John Garrett Underhill Jr. was born in
Brooklyn, the son of
John Garrett Underhill Sr. and Louisa Man Wingate, on August 7, 1915. His mother Louisa Man Wingate was the daughter of General
George Wood Wingate, who played a role in forming the National Rifle Association. His mother died in 1927, when Underhill was only 12 years old. Underhill went on to study and graduate from Harvard College in 1937. In 1940 it was announced that Underhill was to wed Miss Patricia Semple Dunkerson, a graduate of
Vassar College. They were married on June 12 that year at St. Bartholomew's Protestant Episcopal Church. Underhill served as a Technical Editor and later Chief Editor of the War Department's
Military Intelligence Division between July 6, 1943 and May 1946. He was an expert in photography, enemy weapons, and related technical specialities. His role was recognized in a publication of the Memorial Church of All Angels in Twilight Park, Haines Falls, New York. "Report on the Red Army" was a lengthy report written by John Garrett Underhill Jr., under the pseudonym Garrett Underhill. The report was published on October 16, 1949. In the report it was noted how Garrett Underhill was a writer and editor, and served for 3 1/2 years on the War Department General Staff. It noted how he "is owner of a large private collection of Soviet small arms, acquired during a fifteen-year interest in foreign armaments." From late 1949 to the mid-1950s, Underhill was an infrequent contact with the office of the Domestic Contact Service of the
CIA. In 1951, he wrote a 6500 word essay with Ronald Schiller entitled
The Tragedy of the US Army for Look magazine that was published February 13, 1951. After writing the article the Harvard Alumni Bulletin printed Underhill's own words of how he "Got recalled to brown suit service just after finishing a 6500 word article". Following World War II, Underhill volunteered and served as Deputy Director for the Civil Defense of Washington, D.C. An exercise meant to simulate an evacuation in the event of a hydrogen bomb attack called "
Operation Alert" was carried out in 1955. Underhill was outspoken in his criticism of the exercise, stating in the press it was not a "drill but a show". During the exercise he declined heading to the command post for the exercise claiming, it was "so inadequate it couldn't cope with a brushfire threatening a doghouse in a backyard." Samuel Spencer, one of the commissioners who govern the District of Columbia, upon hearing Underhill's criticism ordered his dismissal just as "Operation Alert" began. Underhill took an active interest in family organizations. One letter from November 1950 expressed his interest in "the revival of the three Underhill organizations." He would have ample opportunity to play a hand in that revival between 1954 and 1956 when he served as president of the
Underhill Society of America. Underhill served as a CIA informant and military affairs editor at
Life magazine for five years associated with the death of JFK. ==Death==
