Theodore Alvin Hall (October 20, 1925 – November 1, 1999) was an American physicist and an atomic spy for the Soviet Union, who, during his work on US efforts to develop the first and second atomic bombs during World War II (the Manhattan Project), gave a detailed description of the "Fat Man" plutonium bomb, and of several processes for purifying plutonium, to Soviet intelligence. His brother, Edward N. Hall, was a rocket scientist who worked on intercontinental ballistic missiles for the United States government.
Joseph Medill Patterson Albright (né Reeve; born April 3, 1937) is an American retired journalist and author. A descendent of the Medill-Patterson media family, Albright wrote for the Chicago Sun-Times before becoming a reporter and executive at Newsday. He was later Washington and foreign correspondent for Cox Newspapers, receiving several journalism awards and nominations. Albright has authored three books; two with his wife, fellow reporter Marcia Kunstel. He was formerly married to Madeleine Korbel Albright, who later became the first female U. S. Secretary of State.
Perseus (Персей) was the code name of a hypothetical Soviet atomic spy that, if real, would have allegedly 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.
Morris Cohen (Russian: Моррис Генрихович Коэн, Morris Genrikhovich Koen; July 2, 1910 – June 23, 1995), also known by his alias Peter Kroger, was an American convicted of espionage for the Soviet Union. His wife Lona was also an agent. They became spies because of their communist beliefs.
Lona Cohen (Russian: Леонтина Владиславовна Коэн, Leontina Vladislavovna Koen; January 11, 1913 – December 23, 1992), born Leontine Theresa Petka, also known as Helen Kroger, was an American who spied for the Soviet Union. She is known for her role in smuggling atomic bomb diagrams out of Los Alamos. She was a communist activist before marrying Morris Cohen. The couple became spies because of their communist beliefs.
They were both arrested in Britain in 1961, and convicted of espionage for the Soviet Union the following year. After serving part of a prison sentence, Lona Cohen and her husband were exchanged by the British in 1969. They lived the remainder of their lives in Moscow, teaching spy skills.
Bruno Pontecorvo (Italian: [ponteˈkɔrvo]; Russian: Бру́но Макси́мович Понтеко́рво, Bruno Maksimovich Pontecorvo; 22 August 1913 – 24 September 1993) was an Italian and Soviet nuclear physicist, an early assistant of Enrico Fermi and the author of numerous studies in high energy physics, especially on neutrinos. A convinced communist, he defected to the Soviet Union in 1950, where he continued his research on the decay of the muon and on neutrinos. The prestigious Pontecorvo Prize was instituted in his memory in 1995.
The fourth of eight children of a wealthy Jewish-Italian family, Pontecorvo studied physics at the University of Rome La Sapienza, under Fermi, becoming the youngest of his Via Panisperna boys. In 1934 he participated in Fermi's famous experiment showing the properties of slow neutrons that led the way to the discovery of nuclear fission. He moved to Paris in 1934, where he conducted research under Irène and Frédéric Joliot-Curie. Influenced by his cousin, Emilio Sereni, he joined the French Communist Party, as did his sisters Giuliana and Laura and brother Gillo. The Italian Fascist regime's 1938 racial laws against Jews caused his family members to leave Italy for Britain, France and the United States.
