In addition to the foregoing, we have indentified through two individuals, Floyd C. Miller and Robert Menaker, who were Soviet espionage agents used in the infiltration of the Socialist Workers Party (Trotskyites). Miller was used in connection with the continued infiltration by the Soviets of Mrs. Natalia Trotsky's household in Mexico City. Menaker had been in South America as a representative of the Midland Export Company a firm operated by Michael Burd. Through a review of the Bureau's files on Burd we developed the identities of two person, Nicholas and Maria Fisher, who were, in 1944, attempting to enter the United States in transit to Mexico from the Soviet Union. These two persons are undoubtedly identical with persons named by as "The Paint" (Cheta). It might be noted that their application to pass in transit through the United States was denied by the Interdepartmental Visa Committee. Further investigation is being actively conducted to determine if these persons did succeed in entering the Western Hemisphere at some other time. We also are investigating to determine the ramifications of the possible use of the Midland Export Company as a Soviet espionage cover. It might be noted that the Midland Export Company did come to our attention in connection with our investigation in the Altschuler case. We are actively investigating this matter to develop its full potentialities.
THE MOCASE
Through information we determined that Boris Morros' cover name was Frost (which is the English equivalent of Moros in Russian, although the Soviets used the name as Frost). Alfred K. Stern, according to was designated under the cover name of Louis, and a memorandum prepared by him obtained by us through investigative efforts in February, 1945, was summarized in the information and sent by the MGB in New York City to Moscow. While the above has not assisted materially our efforts in investigating the Mocase, it does furnish corroborative information to that furnished by our informant, Morros.
In addition to the foregoing, there is information from regarding a person designated by the cover of Aida who was working in 1944 for the United Palestine Appeal and the MGB desired to place her with the Committee of Jewish Writers and Artists in New York City where they thought she would be of greater use to them. A tentative identification of this individual has been made as Esther Trebasch Rand, who has been implicated in the espionage notwork in the Mocase and she is a contact of Jack Soble. We are conducting investigation in attempt to verify the tentative identification of Rand.
