Michael Greenberg (born 28 November 1914) has been alleged to have a Soviet spy during the 1940s, but was never charged with espionage. He was also known as Michael Gibson.
Greenberg was born as Menahen Greenberg in Manchester, Lancashire, England, son of a Russian-born father.
Greenberg arrived in the United States in 1939 to attend the Graduate School of Harvard University under a Joseph Hodges Choate Memorial Fellowship from Trinity College, Cambridge. He studied at Harvard from October 1939 to January 1941. Greenberg worked as a Foreign Affairs Economist in the Administrative Division, Enemy Branch, of the Foreign Economic Administration. Elizabeth Bentley stated Greenberg supplied information concerning principally China. The informartion was passed through Mary Price. Greenberg worked closely with Presidential aid Lauchlin Currie.
Greenberg's FBI file is highly redacted. A wiretap in 1945 revealed Greenbergs's co-workers discussing "the charges against him", and remarking that Greenberg would have been better off if he had worked, but that he had never turned out a piece of work in the three years he had been employed by the government.
Greenberg later was employed by the Institute of Pacific Relations.
