Karl-Hermann Geib
Karl–Hermann Geib (12 March 190821 July 1949) was a German physical chemist who, in 1943, developed the "dual temperature exchange sulphide process" (known as the Girdler sulfide process) which is regarded as the "most cost-effective process for producing heavy water". A parallel development of this process was achieved by Jerome S. Spevack at Columbia University and became the basis of post-World War II production of heavy water in the United States at the only remaining facilities located at Wabash River Ordnance Works, near Dana and Newport, Indiana, and the Savannah River Site. Early life Geib was born in Berlin, Germany, on 12 March 1908 to Karl Geib and his wife Maria ( Buddee). He married Hedwig Delbrück and they had four children, Katharina Oestreich (1937-2020), Barbara Pietsch (1938–2016), Ruprecht, born 1939 and Ulrike Heise, born 1940. In 1931, he graduated from Leipzig University and joined the Institute of Physical Chemistry and Electrochemistry of Kai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Berlin
Berlin ( , ) is the capital and largest city of Germany by both area and population. Its 3.7 million inhabitants make it the European Union's most populous city, according to population within city limits. One of Germany's sixteen constituent states, Berlin is surrounded by the State of Brandenburg and contiguous with Potsdam, Brandenburg's capital. Berlin's urban area, which has a population of around 4.5 million, is the second most populous urban area in Germany after the Ruhr. The Berlin-Brandenburg capital region has around 6.2 million inhabitants and is Germany's third-largest metropolitan region after the Rhine-Ruhr and Rhine-Main regions. Berlin straddles the banks of the Spree, which flows into the Havel (a tributary of the Elbe) in the western borough of Spandau. Among the city's main topographical features are the many lakes in the western and southeastern boroughs formed by the Spree, Havel and Dahme, the largest of which is Lake Müggelsee. Due to its l ...

Paul Harteck
Paul Karl Maria Harteck (20 July 190222 January 1985) was an Austrian physical chemist. In 1945 under Operation Epsilon in "the big sweep" throughout Germany, Harteck was arrested by the allied British and American Armed Forces for suspicion of aiding the Nazis in their nuclear weapons program and he was incarcerated at Farm Hall, an English house fitted with covert electronic listening devices, for six months. Education Harteck studied chemistry at the University of Vienna and the Humboldt University of Berlin from 1921 to 1924. He received his doctorate at the latter under Max Bodenstein in 1926. From 1926 to 1928 he was Arnold Eucken’s teaching assistant at the University of Breslau.Hentschel, 1996, Appendix F; see the entry for Paul Harteck.

Operation Osoaviakhim
Operation Osoaviakhim () was a secret Soviet operation under which more than 2,500 former Nazi German specialists (; i.e. scientists, engineers and technicians who worked in specialist areas) from companies and institutions relevant to military and economic policy in the Soviet occupation zone of Germany (SBZ) and the Soviet sector of Berlin, as well as around 4,000 more family members, totalling more than 6,000 people, were transported from former Nazi Germany as war reparations in the Soviet Union. It took place in the early morning hours of October 22, 1946 when MVD (previously NKVD) and Soviet Army units under the direction of the Soviet Military Administration in Germany (SMAD), headed by Ivan Serov. Much related equipment was also moved, the aim being to literally transplant research and production research centers such as the relocated V-2 rocket center of Mittelwerk, from Germany to the Soviet Union, and collect as much material as possible from test centers such as the ...

NKVD
The People's Commissariat for Internal Affairs (russian: Наро́дный комиссариа́т вну́тренних дел, Naródnyy komissariát vnútrennikh del, ), abbreviated NKVD ( ), was the interior ministry of the Soviet Union. Established in 1917 as NKVD of the Russian Soviet Federative Socialist Republic, the agency was originally tasked with conducting regular police work and overseeing the country's prisons and labor camps. It was disbanded in 1930, with its functions being dispersed among other agencies, only to be reinstated as an all-union commissariat in 1934. The functions of the OGPU (the secret police organization) were transferred to the NKVD around the year 1930, giving it a monopoly over law enforcement activities that lasted until the end of World War II. During this period, the NKVD included both ordinary public order activities, and secret police activities. The NKVD is known for its role in political repression and for carrying out the Great ...

Soviet Military Administration In Germany
The Soviet Military Administration in Germany (russian: Советская военная администрация в Германии, СВАГ; ''Sovyetskaya Voyennaya Administratsiya v Germanii'', SVAG; german: Sowjetische Militäradministration in Deutschland, SMAD) was the Soviet military government, headquartered in Berlin-Karlshorst, that directly ruled the Soviet occupation zone of Germany from the German surrender in May 1945 until after the establishment of the German Democratic Republic (GDR) in October 1949. According to the Potsdam Agreement in 1945, the SMAD was assigned the eastern portion of present-day Germany, consisting mostly of central Prussia. Prussia was dissolved by the Allies in 1947 and this area was divided between several German states ''(Länder)''. German lands east of the Oder-Neisse line were annexed by Soviet Union or granted to Poland, and Germans living in these areas were forcibly expelled, having had their property expropriated and been rob ...

Norwegian Heavy Water Sabotage
The Norwegian heavy water sabotage ( nb, Tungtvannsaksjonen; nn, Tungtvassaksjonen) was a series of Allied-led efforts to halt German heavy water production via hydroelectric plants in Nazi Germany-occupied Norway during World War II, involving both Norwegian commandos and Allied bombing raids. During the war, the Allies sought to inhibit the German development of nuclear weapons with the removal of heavy water and the destruction of heavy-water production plants. The Norwegian heavy water sabotage was aimed at the 60 MW Vemork power station at the Rjukan waterfall in Telemark. The hydroelectric power plant at Vemork was built in 1934. It was the world's first site to mass-produce heavy water (as a byproduct of nitrogen fixing), with a capacity of 12 tonnes per year. Before the German invasion of Norway on 9 April 1940, the French Deuxième Bureau removed of heavy water from the Vemork plant in then-neutral Norway. The plant's managing director agreed to lend Fran ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydrogen Sulfide
Hydrogen sulfide is a chemical compound with the formula . It is a colorless chalcogen-hydride gas, and is poisonous, corrosive, and flammable, with trace amounts in ambient atmosphere having a characteristic foul odor of rotten eggs. The underground mine gas term for foul-smelling hydrogen sulfide-rich gas mixtures is ''stinkdamp''. Swedish chemist Carl Wilhelm Scheele is credited with having discovered the chemical composition of purified hydrogen sulfide in 1777. The British English spelling of this compound is hydrogen sulphide, a spelling no longer recommended by the Royal Society of Chemistry or the International Union of Pure and Applied Chemistry. Hydrogen sulfide is toxic to humans and most other animals by inhibiting cellular respiration in a manner similar to hydrogen cyanide. When it is inhaled or it or its salts are ingested in high amounts, damage to organs occurs rapidly with symptoms ranging from breathing difficulties to convulsions and death. Despite this, the ...

Leuna
Leuna is a town in Saxony-Anhalt, eastern Germany, south of Merseburg and Halle, on the river Saale. The town is known for the ''Leunawerke'', at 13 km2 one of the biggest chemical industrial complexes in Germany, where a very wide range of chemicals and plastics is produced. In 1960, Leuna's population was nearly 10,000, but after reunification high unemployment rates and poor living conditions, including pollution from nearby industries, caused significant outward migration. Before the 31 December 2009 incorporation of ten neighbouring municipalities, its population had declined to 6,670. Geography The town Leuna consists of Leuna proper and the following 10 ''Ortschaften'' or municipal divisions:Hauptsatzung der Stadt Leuna July 2020. * |
