Harry Magdoff and espionage Several allege that Harry Magdoff was among a number of persons inside the U . S . government used as information sources by Soviet intelligence . Investigation . An FBI file description says Magdoff and others were probed as part of " a major espionage investigation spanning the years 1945 through 1959 " into a suspected " Soviet spy ring which supposedly had 27 individuals gathering information from at least six Federal agencies . However , none of the subjects were indicted by the Grand Jury . " A mass of previously unremarked materials collectively known as the VENONA project was declassified by the U . S . government in 1995 . Among these were Army decryptions of Soviet cables which revealed there to be some number of American citizens involved in espionage on behalf of the Soviet Union . Magdoff was among those investigated as a member of what was called the Perlo group . The public accusation that Magdoff was working for Soviet intelligence was itself not new ; it had originated with defector Elizabeth Bentley who provided this information to the FBI and later testified to that same effect in open hearings . Bentley told the FBI : Victor Perlo , leader of the group , asked if the material was going to " Uncle Joe " ( Joseph Stalin , General Secretary of the Communist Party of the Soviet Union ) . The Army Signals Intelligence Corp and the FBI conducted a thirty - eight year investigation into communist espionage with mixed results . According to " Counterintelligence Reader " , the Venona project confirms the accuracy of much of Bentley ' s testimony . Critics of Bentley point out that some of her claims were disputed at the time , and that the testimony of Bentley and others before various Congressional committees during the Red Scare was sometimes exaggerated or involved guilt by association assertions . Decrypted cables . According to " A Counterintelligence Reader " , Magdoff was a member of the Perlo group . Magdoff was identified by Arlington Hall cryptographers in the VENONA cables and by FBI counterintelligence investigators as being a possible Soviet information source using the cover name " KANT " as of 1944 . The name " KANT " appears in declassified decryptions from New York to Moscow , dated 5 , 13 and 30 May 1944 . The first is described by the decrypters as being sent from Pavel Ivanovich Fedosimov in which he requests to " telegraph a reply to No . 139 and advise about the possibility of a meeting with KANT . " On 13 May cable , " MAYOR " , according to Arlington Hall counterintelligence Iskhak Abdulovich Akhmerov , reports on the first meeting Elizabeth Bentley had with the Perlo group for the purposes of obtaining secret government information to transmit to the Soviet Union . Magdoff ' s surname was transmitted in the clear . Magdoff at the time was ending a prolonged leave of absence due to a gall bladder operation was unsure of the type of material he could deliver . As a person targeted by Soviet intelligence as a potential recruit , or " probationer " in Soviet parlance , " KANT " was subject to a background check and a request was made for more information . The 30 May cable transmits personal histories for several members of the group . A number of U . S . government agencies ( as well as locations within the U . S . ) were also given cover names . In this case , " DEPOT " is said by NSA analysts to be code for the War Production Board , where Magdoff worked in the Statistics and Tools Divisions . Moscow Archives . In Moscow the request was processed . Evidence was unearthed in the Comintern Archives in the late 1980s has Lt . General Pavel Fitin , head of KGB foreign intelligence operations , requesting of Comintern Secretary General Georgi Dimitrov , information to pursue Magdoff ' s recruitment . This document was published in a book by historians Harvey Klehr , John Earl Haynes , and Fridrikh Igorevich Firsov , and also in the memoirs of the Soviet Case Officer for Julius Rosenberg and Klaus Fuchs ) , Alexandre Feklisov , published in 2001 . The Moscow Center then responded to New York KGB headquarters on 25 February 1945 in Venona decrypt # 179 , 180 . The authors of " Haunted Wood : Soviet Espionage in America " , researchers Allen Weinstein , currently Archivist of the United States , and ex - KGB Officer Alexander Vassiliev say cover name " KANT " was replaced with " TAN " . Moscow Center expressed concern that knowledge of some persons being recruited was widely known among other CPUSA members , so it was not uncommon for code names to change . The code name " TAN " appears Anatoly Gorsky ’ s Memo dated December 1948 , a document from the KGB archives analyzed by Alexander Vassiliev . Gorsky was then a senior official of the Committee of Information ( KI ) , the Soviet agency at the time supervising Soviet foreign intelligence . A top secret internal FBI memo dated 1 February 1956 from Assistant Alan H . Belmont to the Director and head of the FBI ' s Internal Security Section , L . V . Boardman , discusses the advantages and disadvantages of using Venona materials to prosecute suspects . In this memorandum , which remained classified forty - one years until the Moynihan Moynihan Commission on Government Secrecy obtained its release to the public in 1997 , Boardman quotes the 13 May 1944 Venona transcript , which named several members of the Perlo group , including Magdoff . Though Belmont was of the opinion that VENONA evidence could lead to successful convictions , it was ultimately decided , in consideration of compromising the Army Signals Intelligence efforts , that there would not be prosecutions . The memo also raises questions about the disclosure of classified information to unauthorized persons based upon an exception to the hearsay rule requiring expert testimony of cryptographers revealing their practices and techniques to identify specific code names . Skeptical Views . Victor Navasky , editor and publisher of " The Nation " , has written an editorial highly critical of the interpretation of recent work on the subject of Soviet espionage , arguing that historians who rely too much on Venona material are guilty of using every individual mentioned in the cables as prima facie proof of their involvement in Soviet espionage .
