She was married from 1950 ro 1961 to Howland H. Sargeant, the only American to serve as Chairman of the General Conference of UNESCO (6th Session, 1951).
A Republican charge that Cinemactress Myrna Loy and her new State Department husband Howland H. Sargeant had enjoyed a Paris honeymoon at government expense is just not so, declared Georgia's Democratic Congressman Prince Preston Jr. The bridegroom did indeed travel on government funds because he was on an official mission; the honeymoon was coincidental and he paid his wife's bills. Besides, Preston added, since conferences frequently started at 8 a.m. and lasted until 2 a.m., "Paris turned out to be a mighty poor place to spend a honeymoon."Sargeant, a Rhodes Scholar, was a career diplomat who became Assistant Secretary of State for Public Affairs before leaving government to run Radio Liberation, which broadcast to the Soviet Union.
