Perseus (spy)
Perseus was the code name of a hypothetical Soviet atomic spy that, if real, would have breached United States national security by infiltrating Los Alamos National Laboratory during the development of the Manhattan Project, and consequently, would have been instrumental for the Soviets in the development of nuclear weapons. Among researchers of the subject there is some consensus that Perseus was actually a creation of Soviet intelligence. Hypotheses include that "Perseus" was created as a composite of several different spies, disinformation to distract from specific spies, or may have been invented by the KGB to promote itself to the Soviet leadership to obtain more state funding. There were, however, multiple confirmed Soviet spies on the Manhattan project. They included Theodore Hall, George Koval, Morton Sobell, David Greenglass, Julius and Ethel Rosenberg, Klaus Fuchs, and Harry Gold.
Character and history
A reference to the profile of a spy who can be identified with Perseus describes them as an American scientist of young age at the time of the Manhattan Project. If they were real, Perseus would have supposedly been of age to participate in the Spanish Civil War.In the early 1940s Perseus would have been in New York City visiting his sick parents. During his stay in that city, they would have managed to be recruited by the GRU after looking for and contacting Morris Cohen, an American who joined the Communist Party during the Great Depression and worked as a Soviet spy. The meeting with Cohen must have been between September 1941 and July 1942, before Cohen enlisted in the army and left for the Western Front in Europe.
Perseus reportedly introduced themself to Cohen as a physicist who had been invited to join the work at Los Alamos research center. By 1942, Perseus was supposedly already working at Los Alamos, being that they would have started sometime at least 18 months before German physicist and fellow atomic spy Klaus Fuchs, who joined the Manhattan Project in mid-1944. However, Perseus appears to have been recruited by the Soviets around the same time as Fuchs.
According to articles published in Russia by The New Times, Perseus would have collaborated with the Soviet government for purely ideological reasons to the point that they refused any financial rewards in exchange for classified information, since they were convinced that the United States would use the atomic bomb against the Soviet Union, claiming that:
With Morris Cohen in Europe, his wife, Lona Cohen, took it upon herself to travel to Albuquerque on one or two occasions to serve as a carrier. Once there, Lona Cohen would have received information directly from Perseus, and took it to the Soviet consul in New York City, Anatoli Yatskov. This information included crucial details about the Trinity Test, which was detonated in July 1945. In the 1950s, Perseus was supposedly under the control of Rudolf Abel. According to one source, Perseus was supposedly still alive in 1991. Perseus was also referred by or identified with the code names of "Mr. X", "Youngster", FOGEL, PERS and "Mlad"
Possible confirmations of existence
Vladimir Chikov
In April 1991, KGB colonel and public relations officer Vladimir Chikov published articles in the Russian weekly "The New Times" in which he commented on the existence of a Russian spy who worked in the Manhattan Project under the code name of Perseus, giving details of his recruitment and achievements. Regarding the information published by Chikov in The New Times, an article in The Washington Post comments:Anatoli Yatskov
In an interview published in 1992, the former Soviet consul in New York, Anatoli Yatskov, confirmed the existence of Perseus, as an important figure among scientists working on the Manhattan Project. During his tenure as consul, Yatskov used the pseudonym Anatoly Yakovlev and served as a Soviet intelligence agent, coordinating atomic spies in the United States. Yatskov gave details about Perseus' recruitment, how he sent information from New Mexico to New York, and confirmed that the Soviet Union received information from both Klaus Fuchs and Perseus.Morris Cohen and Lona Cohen
In an interview given before his death in 1995, the American-born Soviet spy Morris Cohen confirmed that in addition to Klaus Fuchs, there was a second physicist in the Manhattan Project who worked as a Soviet spy. The details in Cohen's story coincide with the statements of Colonel Vladimir Chikov a few years earlier, such as the recruitment of people close to the Manhattan Project as spies, the existence of an unidentified scientist who collaborated with Soviet intelligence, and the interaction of said scientist with Lona Cohen to transport stolen information.According to Cohen, by the fall of 1994 there were very few people left in Soviet intelligence who knew the real name of the second spy scientist. For her part, shortly before her death in 1992, Lona Cohen had a telephone interview with historian Walter Schneir. In that interview, Lona Cohen confirmed that she had made at least one trip between Albuquerque and New York to transport classified information stolen from the United States, but she could not quite remember who she had interviewed with in New Mexico, saying that it was probably a scientist or physicist.
4th spy at Los Alamos
From the early 1950s till 1995, three Soviet spies had been confirmed to have infiltrated Los Alamos: Klaus Fuchs, David Greenglass and Theodore Hall. Fuchs voluntarily confessed to British MI5 authorities in January 1950 and this subsequently lead to Greenglass in June of that same year. Finally, Hall's involvement was not identified until the release of documents from Venona in 1995, a few years before his death in 1999. After the dissolution of the Soviet Union, publications like those by Chikov and Yatskov strengthened the theory of a possible fourth spy in Los Alamos, who would have been identified as Perseus or FOGEL.Possible rebuttals of existence
Pavel Sudoplatov
In 1994 the lieutenant general and Soviet agent Pavel Sudoplatov published a book titled Special Tasks. In the book, Sudoplatov referred to the statements made by Anatoly Yatskov, and stated that he did not remember that code name and, that in his opinion, it could be that Yatskov or his associates created Perseus to cover the true identities of Soviet informants. However, Sudoplatov also acknowledged that the codename Perseus was used to refer to or cover a number of agents and anonymous sources. Sudoplatov misidentified Bruno Pontecorvo as the spy codenamed "Mlad", who is now identified as Ted Hall by researchers.John Earl Haynes
American Cold War historian John Earl Haynes concluded that Perseus was an invention, relying on the research of authors Joseph Albright, Marcia Kunstel and Gary Kern. In an index of false names, pseudonyms, and real names of spies, Haynes notes under the Perseus entry that:However, Haynes acknowledges that although Perseus was an invention, there must have been a 4th Soviet spy operating in Los Alamos during the development of the Manhattan Project in addition to the three spies identified until 1995: Klaus Fuchs, David Greenglass and Theodore Hall. Haynes and Harvey Klehr detail their argument that Perseus was fictional in "The Atomic Spy Who Never Was: ‘Perseus’ and KGB/SVR Atomic Espionage Disinformation".
Albright and Kunstel
In their book Bombshell: The Secret Story of America's Unknown Atomic Spy Conspiracy, authors Joseph Albright and Marcia Kunstel dedicate the twentieth chapter to Perseus under the title of "The Perseus Myth" in which they conclude that the spy never existed. According to the authors, the KGB may have created Perseus for the purposes of self-promotion, to justify its own existence, and even to secure more state funding.Gary Kern
In 2006 mail that was made public, author Gary Kern explained why he believed Perseus was an invention. Kern believes that Perseus was an extremely risky disinformation operation with multiple objectives, including:- Show that the KGB was vital for the Soviet Union and, after 1991, for Russia.
- Prove that the KGB dominated the field better than the American and British agencies, since the latters were never able to catch the hypothetical Russian agent.
- Give more credit and prestige to Soviet intelligence agents for the development of nuclear weapons, even if this meant diminishing the contribution of Soviet scientists.
- Use Soviet spies of foreign origin living in Russia for propaganda, particularly the Cohens.
- Have some financial gain with the possible sale of the story.
Possible identities
Philip Morrison
In April 1999 American scientist, activist, and president of the Federation of American Scientists from 1970 to 2000, Jeremy Stone, published his memoirs under the title Every Man Should Try: Adventures of a Public Interest Activist.Motivated by an article in The Washington Post about Vladimir Chikov's publications in Russia, Stone decided to take on the subject, and in his book he disclosed conversations and visits he had with someone he knew personally and only identified with the pseudonym "Scientist X", and explained why he believed that this "Scientist X" was the real Perseus.
Despite the use of a pseudonym, thanks to the information in the book, the "Scientist X" was easily identified as Philip Morrison, a physicist from the Massachusetts Institute of Technology. Morrison denied the accusation and gave a solid rebuttal against it, noting that:
- According to Chikov, Perseus participated in the Spanish Civil War, but during this time, Morrison was studying or about to graduate from Berkeley. Also, during his childhood, Morrison contracted polio, which affected his legs to the point that he required a cane to walk, making it unlikely that he could fight in a war.
- According to another source, Perseus would have been in New York City between 1941 and 1942 visiting his parents, but at the time Morrison's parents resided in Philadelphia and his family lived in Pittsburgh.
- Stone thought that the ideas expressed in a phrase attributed to Perseus were similar to ideas expressed by Morrison.
- During a 1994 conversation between the two, Stone was already suspicious of Morrison, so he brought up the subject of Perseus indirectly and Morrison's reaction was so nervous that his knees trembled, but this could be explained by the aftermath of the polio that Morrison suffered in his childhood.
Oscar Seborer
According to historian John Earl Haynes and academic Harvey Klehr, thanks to FBI documents that were declassified in the 2010s, they were able to confirm the existence of a suspected fourth spy who they identified as Oscar Seborer. Seborer was an American engineer who was drafted into the United States Army in 1942 and, like all his siblings, had sympathy for the Communist Party USA.Given his education as an engineer, Seborer was assigned to the Special Engineer Detachment, a program that identified members of the army with specific skills or technical training, and funneled them to the Manhattan Project. However, Haynes and Klehr are emphatic that Seborer should not be identified with Perseus, since while Perseus would have been an invention probably based on Theodore Hall, Seborer's life and profile have no relation to the characteristics attributed to Perseus.
Theodore Hall
According to historian John Earl Haynes and academic Harvey Klehr, although Perseus never really existed, some aspects of his character were based on or coincide with the American Soviet spy and physicist Theodore Hall. These aspects include:- Age: Hall was the youngest scientist working on the Manhattan Project, while the possible reference by Morris Cohen defines Perseus as young and another codename attributed to Perseus is "Youngster".
- Parents' residence: According to Vladimir Chikov, Perseus would have sought to be recruited by the GRU in New York City, after a visit to his parents. Hall's parents lived in New York City, and were coincidentally visited by Hall about the same time.
- Attributed code names: According to Haynes and Klehr, the use of the code name "Mlad" has been wrongly attributed to Perseus, but it actually identified Hall. Likewise, the code name "Youngster" has been attributed to both Hall and Perseus.
- Lifespan: According to Vladimir Chikov, Perseus was still alive in 1991; Hall did not pass away until 1999 and his identity as a spy was not exposed until 1995.
