Harry Gold (11 December 1910 – 28 August 1972) was a laboratory chemist who was convicted of being the “courier” for a number of Soviet spy rings during the Manhattan Project.
Harry Gold was born in Switzerland to poor Russian Jewish immigrants. As a young man he became interested in socialism which eventually led him to contacts within the Communist movement.
In 1940, Gold was activated for Soviet espionage by Jacob Golos, but he was not a recruited agent of the rezidentura. This changed in late 1940 when Soviet Case OfficerSemyon Semenov appropriated Gold from Golos (Gold confession, KF-AS, p. 196). Gold became a formally recruited Soviet agent at this time, and was assigned the codename GUS, or GOOSE. Semyonov remained Gold’s control officer until March 1944.
