VENONA
The Venona project was a United States counterintelligence program initiated during World War II by the United States Army's Signal Intelligence Service (later absorbed by the National Security Agency), which ran from February 1, 1943, until October 1, 1980. It was intended to decrypt messages transmitted by the intelligence agencies of the Soviet Union (e.g. the NKVD, the KGB, and the GRU). Initiated when the Soviet Union was an ally of the US, the program continued during the Cold War, when the Soviet Union was considered an enemy. During the 37-year duration of the Venona project, the Signal Intelligence Service decrypted and translated approximately 3,000 messages. The signals intelligence yield included discovery of the Cambridge Five espionage ring in the United Kingdom and Soviet espionage of the Manhattan Project in the U.S. (known as Project Enormous). Some of the espionage was undertaken to support the Soviet atomic bomb project. The Venona project remained secret for m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Julius And Ethel Rosenberg
Julius Rosenberg (May 12, 1918 – June 19, 1953) and Ethel Rosenberg (; September 28, 1915 – June 19, 1953) were American citizens who were convicted of spying on behalf of the Soviet Union. The couple were convicted of providing top-secret information about radar, sonar, jet propulsion engines, and valuable nuclear weapon designs. Convicted of espionage in 1951, they were executed by the federal government of the United States in 1953 at Sing Sing Correctional Facility in Ossining, New York, becoming the first American civilians to be executed for such charges and the first to receive that penalty during peacetime. Other convicted co-conspirators were sentenced to prison, including Ethel's brother, David Greenglass (who had made a plea agreement), Harry Gold, and Morton Sobell. Klaus Fuchs, a German scientist working in Los Alamos, was convicted in the United Kingdom. For decades many people including the Rosenbergs' sons (Michael and Robert Meeropol) maintained that Juliu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cold War
The Cold War is a term commonly used to refer to a period of geopolitical tension between the United States and the Soviet Union and their respective allies, the Western Bloc and the Eastern Bloc. The term '' cold war'' is used because there was no large-scale fighting directly between the two superpowers, but they each supported major regional conflicts known as proxy wars. The conflict was based around the ideological and geopolitical struggle for global influence by these two superpowers, following their temporary alliance and victory against Nazi Germany and Imperial Japan in 1945. Aside from the nuclear arsenal development and conventional military deployment, the struggle for dominance was expressed via indirect means such as psychological warfare, propaganda campaigns, espionage, far-reaching embargoes, rivalry at sports events, and technological competitions such as the Space Race. The Western Bloc was led by the United States as well as a number of other First W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gene Grabeel

Bill Weisband
William Weisband, Sr. (August 28, 1908 – May 14, 1967) was a Ukrainian-American cryptanalyst and NKVD agent (code name 'LINK'), best known for his role in revealing U.S. decryptions of Soviet diplomatic and intelligence codes to Soviet intelligence. Background Weisband was born in Odessa, Russian Empire (now Ukraine), in 1908. He emigrated to the United States in the 1920s and became a naturalized United States citizen in 1938. He was drafted into the United States Army in 1942, and was assigned to signals intelligence duties. Espionage career From 1941 to 1942, Weisband was the NKVD agent handler for Jones Orin York, who worked at the Northrop Corporation. After joining the U.S. Army's Signals Intelligence Service (SIS) in 1942, he performed signals intelligence and communications security duties in North Africa and Italy, where he made some important friends before returning to the "Russian Section" at Arlington Hall, where SIS had established its headquarters in June ...

Signal Intelligence Service
The Signal Intelligence Service (SIS) was the United States Army codebreaking division through World War II. It was founded in 1930 to compile codes for the Army. It was renamed the Signal Security Agency in 1943, and in September 1945, became the Army Security Agency. For most of the war it was headquartered at Arlington Hall (former campus of Arlington Hall Junior College for Women), on Arlington Boulevard in Arlington, Virginia, across the Potomac River from Washington (D.C.). During World War II, it became known as the Army Security Agency, and its resources were reassigned to the newly established National Security Agency (NSA). History The Signal Intelligence Service was a part of the U.S. Army Signal Corps for most of World War II. At that time the Signal Corps was a bureau in the Headquarters, Department of the Army, in addition to being a branch of the Army to which personnel were commissioned or appointed. The Signal Corps supplied the Army with communications and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soviet Atomic Bomb Project
The Soviet atomic bomb project was the classified research and development program that was authorized by Joseph Stalin in the Soviet Union to develop nuclear weapons during and after World War II. Although the Soviet scientific community discussed the possibility of an atomic bomb throughout the 1930s, going as far as making a concrete proposal to develop such a weapon in 1940, the full-scale program was not initiated and prioritized until Operation Barbarossa. Because of the conspicuous silence of the scientific publications on the subject of nuclear fission by German, American, and British scientists, Russian physicist Georgy Flyorov suspected that the Allied powers had secretly been developing a "superweapon" since 1939. Flyorov wrote a letter to Stalin urging him to start this program in 1942. Initial efforts were slowed due to the German invasion of the Soviet Union and remained largely composed of the intelligence gathering from the Soviet spy rings working in the U. ...

Donald Duart Maclean
Donald Duart Maclean (; 25 May 1913 – 6 March 1983) was a British diplomat who conveyed government secrets to the Soviet Union. As an undergraduate, Maclean openly proclaimed his left-wing views, and was recruited into the Soviet intelligence service, then known as the NKVD. He entered the Civil Service and in 1938, he was made Third Secretary at the Paris embassy. He then served in London and was sent to Washington, D.C. from 1944 to 1948, achieving promotion to First Secretary. He was posted to Egypt and then was appointed head of the American Department in the Foreign Office. The Soviets helped Maclean to defect to Moscow in 1951. In Moscow, Maclean worked as a specialist on British policy and relations between the Soviet Union and NATO. He died there on 6 March 1983. Childhood and school Born in Marylebone, London, Donald Duart Maclean was the son of Sir Donald Maclean and Gwendolen Margaret Devitt. His father was chosen as chairman of the rump of the 23 independent MPs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Signals Intelligence
Signals intelligence (SIGINT) is intelligence-gathering by interception of ''signals'', whether communications between people (communications intelligence—abbreviated to COMINT) or from electronic signals not directly used in communication (electronic intelligence—abbreviated to ELINT). Signals intelligence is a subset of intelligence collection management. As classified and sensitive information is usually encrypted, signals intelligence in turn involves the use of cryptanalysis to decipher the messages. Traffic analysis—the study of who is signaling whom and in what quantity—is also used to integrate information again. History Origins Electronic interceptions appeared as early as 1900, during the Boer War of 1899–1902. The British Royal Navy had installed wireless sets produced by Marconi on board their ships in the late 1890s, and the British Army used some limited wireless signalling. The Boers captured some wireless sets and used them to make vital transmis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cambridge Five
The Cambridge Spy Ring was a ring of spies in the United Kingdom that passed information to the Soviet Union during World War II and was active from the 1930s until at least into the early 1950s. None of the known members were ever prosecuted for spying. The number and membership of the ring emerged slowly, from the 1950s onwards. The general public first became aware of the conspiracy after the sudden flight of Donald Maclean (cryptonym: Homer) and Guy Burgess (cryptonym: Hicks) to the Soviet Union in 1951. Suspicion immediately fell on Harold "Kim" Philby (cryptonyms: Sonny, Stanley), who eventually fled the country in 1963. Following Philby's flight, British intelligence obtained confessions from Anthony Blunt (cryptonym: Johnson) and then John Cairncross (cryptonym: Liszt), who have come to be seen as the last two of a group of five. Their involvement was kept secret for many years: until 1979 for Blunt, and 1990 for Cairncross. The moniker Cambridge Four evolved to become ...

Guy Burgess
Guy Francis de Moncy Burgess (16 April 1911 – 30 August 1963) was a British diplomat and Soviet agent, and a member of the Cambridge Five spy ring that operated from the mid-1930s to the early years of the Cold War era. His defection in 1951 to the Soviet Union, with his fellow spy Donald Maclean, led to a serious breach in Anglo-United States intelligence co-operation, and caused long-lasting disruption and demoralisation in Britain's foreign and diplomatic services. Born into a middle-class family, Burgess was educated at Eton College, the Royal Naval College, Dartmouth, and Trinity College, Cambridge. An assiduous networker, he embraced left-wing politics at Cambridge and joined the British Communist Party. He was recruited by Soviet intelligence in 1935, on the recommendation of the future double-agent Harold "Kim" Philby. After leaving Cambridge, Burgess worked for the BBC as a producer, briefly interrupted by a short period as a full-time MI6 intelligence officer, bef ...
