Robert Owen Menaker
Information from reflects that Robert Owen Menaker operated as a Soviet agent in 1944 and was a contact of Floyd Cleveland Miller. We had an active investigation on Menaker and he became suspicious that he was under investigation and contacted former Special Agent Thomas M. McDade, who arranged for Menaker to be interviewed. Pursuant to this Menaker voluntarily appeared at the New York Office on February 8, 1951, and was interviewed. He admitted espionage activities for the Soviets from 1937 to 1948. He identified as his superior Gregory L. Rabinovitch, who had been in the United States from 1930 to 1939, as the head of the Soviet Red Cross. He also identified Joseph Katz as his superior who furnished in some detail instructions for his activities in penetrating the Trotskyite movement. He also admitted working for the Midland export Corporation at the request of the Soviets and traveling to South America for that company. The activities of Michael Burd, the head of the Midland Export Corporation, will be discussed separately in this memorandum. We expect to be able to obtain in greater detail from Menaker his activities in Soviet espionage. He was apparently not too important a Soviet agent as he could never learn to keep his mouth shut about his work. We are following this matter closely.
Floyd Cleveland Miller
Information from reflects that Floyd Cleveland Miller was used successfully by the Soviets in infiltrating the Socialist Workers Party in 1944. The information also indicates he made a trip to Mexico and had conferred with Trotsky's widow. We determined through investigation that Miller under the name of Michael Cort, had been in the Socialist Workers Party from 1939 to 1945. Miller voluntarily appeared at the New York office on February 9, 1951. He admitted joining the Communist Party in the mid 1930's and in 1937 being approached by his friend, Menaker, to work in soviet espionage. He worked first under Gregory L. Rabinovitch, and later under Joseph Katz, as well as under a number of other Soviet superiors whom we are attempting to identify. One of his first jobs in Soviet espionage
