During this period she associated with a group of Soviet spies that included Julius Rosenberg, Joel Barr, Alfred Salant, Morton Sobell, David Greenglass and William Perl. Rosenberg collected the material and arranged for it to be copied by Semyon Semyonov. This material then went to Alexander Feklissov, who later claimed that between 1943 and 1945 the Rosenberg group "had given me over 20,000 pages of technical documents plus another 12,000 pages of the complete design manual for the first U.S. jet fighter, the P-80 Shooting Star." (2)

On 16th June, 1950, David Greenglass was arrested. The New York Tribune quoted him as saying: "I felt it was gross negligence on the part of the United States not to give Russia the information about the atom bomb because he was an ally." (3) According to the New York Times, while waiting to be arraigned, "Greenglass appeared unconcerned, laughing and joking with an FBI agent. When he appeared before Commissioner McDonald... he paid more attention to reporters' notes than to the proceedings." (4) Greenglass's attorney said that he had considered suicide after hearing of Gold's arrest. He was also held on $1000,000 bail.

On 6th July, 1950, the New Mexico federal grand jury indicted Greenglass on a charge of conspiring to commit espionage in wartime on behalf of the Soviet Union. Specifically, he was accused of meeting with Harry Gold in Albuquerque on 3rd June, 1945, and producing "a sketch of a high explosive lens mold" and receiving $500 from Gold. It was clear that Gold had provided the evidence to convict Greenglass.

The New York Daily Mirror reported on 13th July that Greenglass had decided to join Harry Gold and testify against other Soviet spies. "The possibility that alleged atomic spy David Greenglass has decided to tell what he knows about the relay of secret information to Russia was evidenced yesterday when U. S. Commissioner McDonald granted the ex-Army sergeant an adjournment of proceedings to move him to New Mexico for trial." (5) Four days later the FBI announced the arrest of Julius Rosenberg. The New York Times reported that Rosenberg was the "fourth American held as a atom spy". (6)

NKVD now made plans to get those members of the Rosenberg network who had not been arrested out of the country. As Alexander Feklissov has pointed out: "William Perl was still living in Cleveland where he had been kept dormant. Amid the hysteria of the times it was inconceivable to send a Soviet citizen to Cleveland to help him leave the country. Who, then, could possibly fulfill the mission? The underground network was disintegrating and every new contact could trigger new arrests... Even though he had been hibernating for four years, Perl had been a very important agent and it was a moral duty to save him." (7)

It was decided to send Vivian Glassman to see William Perl. She was a low profile member of the network and they were convinced that the FBI was unaware that she was a spy. This is also true of Perl but he had met her sometime before when she was in the company of Julius Rosenberg, Joel Barr and Alfred Sarant. On 21st July, 1950, a NKVD agent paid her a visit and asked her to "undertake an important mission: go to Cleveland, contact Perl and warn him that he could be arrested, hand him $2,000 and detailed instructions to arrange his escape to Mexico." (8)

Glassman arrived at the home of Perl on 23rd July, 1950. Perl later commented: "About noon on this Sunday afternoon, while I was preparing to go out on a picnic, Vivian Glassman suddenly appeared.... I was quite surprised. I recognized her as a friend of Joel Barr's. I asked her to come in. She acted somewhat mysteriously. She proceeded to take some paper which I had lying around and start writing on it and motioning me to read what she had written and, well she wrote to the effect that she had instructions from a person unknown to her, in New York, to travel to Cleveland to get in touch with an aeronautical engineer to give him money and instructions to leave the country, and I believe she mentioned Mexico in that connection.... Well, I was very upset. I mentioned something about... I did not understand what this was all about. I believe I possibly mentioned that I thought it was a trap of some kind, words to that effect. I was feeling rather incoherent at the time.... Well, I told her that I thought she had better go. I ushered her out." (9)

Perl believed that Vivian Glassman had been turned by the FBI and it was an attempt to trap him. He had been interviewed by the FBI the previous week. After consulting his lawyer he went to the FBI and reported her visit: "I had been questioned by the FBI for the previous week or two, and this coming on top of it all, made me feel very, well, upset, so I decided that I should consult... a lawyer, which I tried to, the following morning... Of course I had been reading about the spy cases in the papers. She did mention in writing that she knew Julius Rosenberg. Well, here was something I was being asked, to flee the country for some reason. And so all I could think of was that somebody was trying to trap me into something, since I had no reason to leave."

The FBI now carried out an investigation into Glassman. They discovered that during the Second World War she associated with a group of Soviet spies that included Julius Rosenberg, Joel Barr, Alfred Salant, William Perl, Morton Sobell and David Greenglass. A file that had been created on 8th March, 1950, mentioned that she had worked with Rosenberg at the Army Signal Corps Engineering Laboratories at Fort Monmouth, New Jersey. According to this FBI file she had access to secret information in this work. (10)

Vivian Glassman was interviewed by the FBI on 4th August, 1950. "She claimed that she did not know the man who gave her $2,000 to take to William Perl. "She admitted the individual at the door and stated that his identity was unknown to her. She stated that although she did not know the man, she thought she could trust him as long as he was a friend of Joel Barr... He then gave her a roll of money and stated 'here is 2,000 dollars'. He then departed."

She also admitted that she knew both Julius and Ethel Rosenberg. "She said she first met them while canvassing for the American Labor Party: "She became friendly with Rosenberg's wife and visited Rosenberg socially thereafter. She denied that she ever did any work for Julius Rosenberg or that he had asked her to. She stated Rosenberg had been in her apartment at 131 East Seventh Street on several occasions when he had taken her home from Knickerbocker Village late at night, she denied that the apartment was used by Rosenberg for photographic work or that he ever had use of the apartment for any purpose." (11)

In an interview she gave to the FBI on 8th August 1950, Vivian Glassman admitted that she had enjoyed a close relationship with Joel Barr. He introduced her to his friend, Alfred Salant. "She was in his company on numerous occasions thereafter when she was dating Joel Barr and the three of them made a canoe trip together to the Old Forge, Thendara, NY, in summer 1944." (12)

Vivian Glassman appeared before the Rosenberg Grand Jury on 14th August, 1950. The FBI report stated: "Vivian Glassman was taken before the grand jury this afternoon at 12.30 P.M. and again refused to answer questions on the grounds that it might incriminate or degrade her." The FBI considered that Glassman might well be a spy but her name, unlike Rosenberg, Barr, Salant, Sobell, and Greenglass, had not come up in the Venona transcripts, it was decided not to charge her with spying.

William Perl was arrested on 15th March 1951. He was interviewed by the FBI and prosecutors involved in the investigation of the atom spies. Perl later recalled that Roy Cohn was at the meeting: "Roy Cohn informed me that... if I did not confess I would be indicated." He said he replied to Cohn that "I had nothing to confess, but whatever he or anybody else had against me, I would very much like to hear it open court." (13)

A few months later William Perl appeared before the Rosenberg Grand Jury. He denied knowing Julius Rosenberg and Morton Sobell and as a result he was charged with perjury. His trial began on 18th March, 1953. Perl's defense hinged mainly on his subjective interpretation of the word "know" in the grand jury's questions to him. He claimed that at first he honestly had forgotten "knowing" both Rosenberg and Sobell. It has been claimed that "his memory may well have been influenced by his admitting eagerness to disassociate himself from his accused classmates". Perl pointed out that a FBI agent had told him that "Rosenberg and Sobell are going to fry". Perl told the court: "The newspaper details of the case... and the FBI's strong emphasis to me that Rosenberg and Sobell faced the death penalty horrified and shocked me." (14)

It was also revealed that in the week before the visit of Vivian Glassman, FBI agents had questioned him about Rosenberg, Sobell, Joel Barr and Alfred Sarant. "They... stated that they had evidence that Barr and Sarant were members of the Communist Party". He said he had no personal knowledge that either man was a member of the Communist Party of the United States but had played down his relationship with them. "I was afraid I would lose my job if they (the loyalty board) got an impression that I was associated with Communists."

The Perl jury returned a verdict of guilty, with a recommendation of clemency. However, the Assistant United States Attorney Lloyd Francis MacMahon urged "a more severe sentence" because Perl "was concealing his personal and direct knowledge of the activities of Julius Rosenberg, Morton Sobell and other persons involved in espionage on behalf of the Soviet Union." The judge took MacMahon's advice and gave Perl the maximum sentence - five years. (15)
