Operation Big
Operation Big was an operation of the Alsos Mission, the Allied seizure of facilities, materiel, and personnel related to the German nuclear weapon project during World War II. It was tasked with sweeping several targeted towns in the area of southwest Germany designated to the French First Army, including Hechingen, Bisingen, Haigerloch, and Tailfingen. Operating behind German lines the U.S. task force successfully carried out its mission of seizing or destroying all project related assets and capturing its top scientists in the last week of April and first week of May, 1945. History Shortly after the liberation of Paris it was decided to bomb German nuclear facilities wherever they lay in order to deprive the Soviet Union of their technology and personnel, unless American troops could get to them first. Worried that French forces might beat the US to Werner Heisenberg's laboratory in Hechingen, Alsos chief Lt-Col Boris Pash hastily organized a flying column of combat engineers ...

Vichy Government
Vichy France (french: Régime de Vichy; 10 July 1940 – 9 August 1944), officially the French State ('), was the fascist French state headed by Marshal Philippe Pétain during World War II. Officially independent, but with half of its territory occupied under harsh terms of the armistice, it adopted a policy of collaboration with Nazi Germany, which occupied the northern and western portions before occupying the remainder of Metropolitan France in November 1942. Though Paris was ostensibly its capital, the collaborationist Vichy government established itself in the resort town of Vichy in the unoccupied "Free Zone" (), where it remained responsible for the civil administration of France as well as its colonies. The Third French Republic had begun the war in September 1939 on the side of the Allies. On 10 May 1940, it was invaded by Nazi Germany. The German Army rapidly broke through the Allied lines by bypassing the highly fortified Maginot Line and invading through Be ...

Intelligence Of World War II
Intelligence has been defined in many ways: the capacity for abstraction, logic, understanding, self-awareness, learning, emotional knowledge, reasoning, planning, creativity, critical thinking, and problem-solving. More generally, it can be described as the ability to perceive or infer information, and to retain it as knowledge to be applied towards adaptive behaviors within an environment or context. Intelligence is most often studied in humans but has also been observed in both non-human animals and in plants despite controversy as to whether some of these forms of life exhibit intelligence. Intelligence in computers or other machines is called artificial intelligence. Etymology The word ''intelligence'' derives from the Latin nouns '' intelligentia'' or '' intellēctus'', which in turn stem from the verb '' intelligere'', to comprehend or perceive. In the Middle Ages, the word ''intellectus'' became the scholarly technical term for understanding, and a translation f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Operation Epsilon
Operation Epsilon was the codename of a program in which Allied forces near the end of World War II detained ten German scientists who were thought to have worked on Nazi Germany's nuclear program. The scientists were captured between May 1 and June 30, 1945, as part of the Allied Alsos Mission, mainly as part of its Operation Big sweep through southwestern Germany. They were interned at Farm Hall, a bugged house in Godmanchester, near Cambridge, England, from July 3, 1945, to January 3, 1946. The primary goal of the program was to determine how close Nazi Germany had been to constructing an atomic bomb by listening to their conversations. List of scientists The following German scientists were captured and detained during Operation Epsilon: * Erich Bagge * Kurt Diebner * Walther Gerlach * Otto Hahn * Paul Harteck * Werner Heisenberg * Horst Korsching * Max von Laue * Carl Friedrich von Weizsäcker * Karl Wirtz Transfer to England The scientists captured in Germany by the Al ...

Otto Hahn
Otto Hahn (; 8 March 1879 – 28 July 1968) was a German chemist who was a pioneer in the fields of radioactivity and radiochemistry. He is referred to as the father of nuclear chemistry and father of nuclear fission. Hahn and Lise Meitner discovered radioactive isotopes of radium, thorium, protactinium and uranium. He also discovered the phenomena of atomic recoil and nuclear isomerism, and pioneered rubidium–strontium dating. In 1938, Hahn, Lise Meitner and Fritz Strassmann discovered nuclear fission, for which Hahn received the 1944 Nobel Prize for Chemistry. Nuclear fission was the basis for nuclear reactors and nuclear weapons. A graduate of the University of Marburg, Hahn studied under Sir William Ramsay at University College London and at McGill University in Montreal under Ernest Rutherford, where he discovered several new radioactive isotopes. He returned to Germany in 1906; Emil Fischer placed a former woodworking shop in the basement of the Chemical Institute ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Karl Wirtz
Karl Eugen Julius Wirtz (24 April 1910 – 12 February 1994) was a German nuclear physicist, born in Cologne. He was arrested by the allied British and American Armed Forces and incarcerated at Farm Hall for six months in 1945 under Operation Epsilon. Education From 1929 to 1934, Wirtz studied physics, chemistry, and mathematics at the University of Bonn, the Albert Ludwigs University of Freiburg, and the University of Breslau. He received his doctorate in 1934 under C. Schäfer. From 1935 to 1937, he was a teaching assistant to Carl-Friedrich Bonhoeffer at the University of Leipzig. During this period, he became a member of the Nationalsozialistischer Lehrerbund (''NSLB'', ''National Socialist Teachers League''), but not the Nationalsozialistische Deutsche Arbeiterpartei (''NSDAP, National Socialist German Workers Party''). Some of the more established scientists, such as Max von Laue, could demonstrate more autonomy than the younger and less established scientists. This ...

Max Von Laue
Max Theodor Felix von Laue (; 9 October 1879 – 24 April 1960) was a German physicist who received the Nobel Prize in Physics in 1914 for his discovery of the diffraction of X-rays by crystals. In addition to his scientific endeavors with contributions in optics, crystallography, quantum theory, superconductivity, and the theory of relativity, Laue had a number of administrative positions which advanced and guided German scientific research and development during four decades. A strong objector to Nazism, he was instrumental in re-establishing and organizing German science after World War II. Biography Early years Laue was born in Pfaffendorf, now part of Koblenz, Germany, to Julius Laue and Minna Zerrenner. In 1898, after passing his ''Abitur'' in Strassburg, he began his compulsory year of military service, after which in 1899 he started to study mathematics, physics, and chemistry at the University of Strassburg, the University of Göttingen, and the Ludwig Maximilian Uni ...

Carl Friedrich Von Weizsäcker
Carl Friedrich Freiherr von Weizsäcker (; 28 June 1912 – 28 April 2007) was a German physicist and philosopher. He was the longest-living member of the team which performed nuclear research in Germany during the Second World War, under Werner Heisenberg's leadership. There is ongoing debate as to whether or not he and the other members of the team actively and willingly pursued the development of a nuclear bomb for Germany during this time. A member of the prominent Weizsäcker family, he was son of the diplomat Ernst von Weizsäcker, elder brother of the former German President Richard von Weizsäcker, father of the physicist and environmental researcher Ernst Ulrich von Weizsäcker and father-in-law of the former General Secretary of the World Council of Churches Konrad Raiser. Weizsäcker made important theoretical discoveries regarding energy production in stars from nuclear fusion processes. He also did influential theoretical work on planetary formation in the ...

Nuclear Reactor
A nuclear reactor is a device used to initiate and control a fission nuclear chain reaction or nuclear fusion reactions. Nuclear reactors are used at nuclear power plants for electricity generation and in nuclear marine propulsion. Heat from nuclear fission is passed to a working fluid (water or gas), which in turn runs through steam turbines. These either drive a ship's propellers or turn electrical generators' shafts. Nuclear generated steam in principle can be used for industrial process heat or for district heating. Some reactors are used to produce isotopes for medical and industrial use, or for production of weapons-grade plutonium. , the International Atomic Energy Agency reports there are 422 nuclear power reactors and 223 nuclear research reactors in operation around the world. In the early era of nuclear reactors (1940s), a reactor was known as a nuclear pile or atomic pile (so-called because the graphite moderator blocks of the first reactor were placed into a tall pi ...
