Theodore Bayer was president of the Russky Golos, or Russian Voice Publishing Company, which published an anti-capitalist Russian-language newspaper during the Great Depression and World War II. Russky Golos was funded by the Comintern and by advertising, commercial newsstand and subscription sales. Its editorial position was closely aligned with the Communist Party of the United States (CPUSA). Bayer was part of a Soviet military intelligence (GRU) network.
As president of Russky Golos, Bayer got to know John Hazard Reynolds, who provided financial support to a publication entitled Soviet Russia Today, and recommended him to Communist Party of the United States (CPUSA) General Secretary Earl Browder.
In a July 1943 Venona project decryption sent by the New York GRU Rezident Pavel Mikhailov to Moscow, Bayer is credited with describing a CPUSA source near President Franklin Roosevelt as a woman 'from an aristocratic family, who has known the President and his wife for a long time, evidently a secret member of the CPUSA.' The message included praise of Stalin's leadership and an allegation that Madame Chiang Kai-shek was "a narcotics addict." The GRU later identified the woman as Josephine Treslow.
The Report of the Subversive Activities Control Board found Theodore Bayer to be a high level and important member of the the CPUSA.
