Louise Rosenberg Bransten was born October 10, 1908, at Berkeley, California. She was independently wealthy through inheritance and received, in the late 1940s, an income of approximately $40,000 annually. She was formerly married to Richard Bransten, alias Bruce Minton, a former editor of the Communist party USA publication New Masses, who was expelled from the Communist Party because of differences over the expulsion of Earl Browder as head of the party.
Louise Bransten first met Gregori Kheifets in 1942, and soon afterward commenced an intimate association with him. In fact, Bransten was unquestionably the closest associate of Kheifets, and he frequently confided in her.
While Louise Bransten's open activities appeared to have been related principally to the American-Russian Institute, a Communist- front organization, she frequently met with individuals such as Haakon Chevalier, professor of Romance languages at the University of California, Joseph North, editor of New Masses; Earl Browder, his brother, William Browder, Lement Upham Harris, Gerhart Eisler and Nathan Gregory Silvermaster.
During the organizing conference of the United Nations in San Francisco in the spring of 1045, Louise Bransten entertained Dmitri Manuilsky, the head of the delegation from the Ukraine. Manuilsky a member of Stalin's inner circle and principal spokesman for the Comintern.

Louise Bransten later moved from San Francisco to New York City. Shortly after moving to New York, she established contact with Pavel Mikhailov, who at the time was head of Red Army Intelligence' activity in the New York area.
