Baker shows up in [[Venona project]] traffic only under the cover name "Son"; he may also be "Rudi". The identification comes from coded correspondence between the [[Comintern]] and the CPUSA in Russia's RTsKhIDNI archive (495-184), which contains dozens of messages from Brother in Moscow to Father and Son in the United States. Annotations on these messages identify Brother as Dimitrov and Father as CPUSA General Secretary [[Earl Browder]]. In these messages Son is the head of the CPUSA's covert arm, which Baker took over in mid 1938 after [[Whittaker Chambers]] defection. None of the Comintern messages to Son were sent until after Baker visited Moscow in January of 1939 to brief Commintern officials on the status of the CPUSA secret apparatus after Baker took over. In May of 1942 General Pavel Fitin, the head of [[KGB]] foreign intellignece directorate states in a message to Dimitrov found in the Comintern Archives, "We are forwarding a telegram we received from New York addressed to you from Rudy," and the telegram is signed "Son". | Baker shows up in [[Venona project]] traffic only under the cover name "Son"; he may also be "Rudi".
