In the Autumn 2000 issue of the journal '' Intelligence and National Security '' , Lowenthal published the article " Venona and Alger Hiss , " which " claimed not only to show that ALES was not Hiss , but that all the VENONA cables were unreliable . " ( In 2003 , U.S. Air Force historian Eduard Mark published a rebuttal , also in '' Intelligence and National Security '' that used VENONA 1822 to trace " ALES " as working for State ( 1945 ) , with relatives ( Donald Hiss , brother ) also working in the federal government , had been a GRU agent since the mid-1930s ( with Whittaker Chambers in the Ware Group , had attended the Yalta Conference , and had returned from travel to the US by 30 March 1945 – all descriptions which fit Alger Hiss . In his 2000 article , Lowenthal had accused Aleksandr Vassiliev , co-author of '' The Haunted Wood '' ( 1999 ) with Allen Weinstein , of sloppiness . In July 2001 , Vassiliev sued Lowenthal indirectly for libel by suing Frank Cass & Co. , publisher of '' Intelligence and National Security '' , in the High Court of Justice in London . In January 2003 , Frank Cass 's lawyers offered Alexander Vassiliev to settle the monetary claim for more than 2,000 British pounds and promised not to republish the John Lowenthal article . Vassiliev rejected the offer . In May 2003 Frank Cass proposed to settle the case for 7,500 pounds , but Vassiliev rejected that offer , too . The trial '' Vassiliev vs Frank Cass '' started 9 June 2003 and concluded on 13 June 2003 , with Judge David Eady presiding . Frank Cass & Co. prevailed on the basis of " fair comment . " By 2003 , Lowenthal had helped son Tony Hiss prepare the Alger Hiss Papers before offering them to the Harvard Law School 's library
