Robert Talbott Miller III (April 5, 1910 – January 1999) was an American citizen who worked in the United States Office of the Coordinator of Inter-American Affairs during World War II.
Sometime that same year, the Millers relocated to Washington D.C. so that he could take employment as an analyst for the Office of the Coordinator of Inter-American Affairs (OCIAA) in the Department of Commerce at a good salary.
About this time, Miller allegedly began supplying information to Elizabeth Bentley for the Golos network.
The material Miller allegedly provided Bentley for transmission to Soviet intelligence always concerned Communist or Russian activities in Latin America.
In September 1941, the Hemisphere News Service moved to Washington D.C. and became the Export Information Bureau, managed by Joseph Gregg, and received a contract to do exclusive research work for the Coordinator of Inter-American Affairs.
Miller was also a close associate of Maurice Halperin, who worked for the OSS, State Department, and Soviet intelligence.
