Auergesellschaft
The industrial firm ''Auergesellschaft'' was founded in 1892 with headquarters in Berlin. Up to the end of World War II, ''Auergesellschaft'' had manufacturing and research activities in the areas of gas mantles, luminescence, rare earths, radioactivity, and uranium and thorium compounds. In 1934, the corporation was acquired by the German corporation Degussa. In 1939, their Oranienburg plant began the development of industrial-scale, high-purity uranium oxide production. Special Soviet search teams, at the close of World War II, sent ''Auergesellschaft'' equipment, material, and staff to the Soviet Union for use in their nuclear weapon project. In 1958 ''Auergesellschaft'' merged with the Mine Safety Appliances Corporation, a multinational US corporation. Auergesellschaft became a limited corporation in 1960. History The ''Deutsche Gasglühlicht AG'' (Degea, German Gas Light Company), was founded in 1892 through the combined efforts of the Jewish entrepreneur and banker Geheimrat ...

Oranienburg
Oranienburg () is a town in Brandenburg, Germany. It is the capital of the district of Oberhavel. Geography Oranienburg is a town located on the banks of the Havel river, 35 km north of the centre of Berlin. Division of the town Oranienburg consists of nine districts: * Friedrichsthal * Germendorf * Lehnitz * Malz * Oranienburg * Sachsenhausen * Schmachtenhagen * Wensickendorf * Zehlendorf History Originally named Bötzow, the town of Oranienburg dates from the 12th century and was first mentioned in 1216. Margrave Albert the Bear (ruled 1157–1170) allegedly ordered the construction of a castle on the banks of the Havel. Around the castle stood a settlement of traders and craftsmen. In 1646, Friedrich Wilhelm I of Brandenburg married Louise Henriette of Orange-Nassau (German: ''Oranien-Nassau'').

Carl Auer Von Welsbach
Carl Auer von Welsbach (1 September 1858 – 4 August 1929), who received the Austrian noble title of Freiherr Auer von Welsbach in 1901, was an Austrian scientist and inventor, who separated didymium into the elements neodymium and praseodymium in 1885. He was also one of three scientists to independently discover the element lutetium (which he named ''cassiopeium''), separating it from ytterbium in 1907, setting off the longest priority dispute in the history of chemistry. He had a talent not only for making scientific advances, but also for turning them into commercially successful products. His work on rare-earth elements led to the development of the ferrocerium "flints" used in modern lighters, the gas mantle that brought light to the streets of Europe in the late 19th century, and the metal-filament light bulb. He took the phrase ''plus lucis'', meaning "more light", as his motto. Early life Carl Auer was born in Vienna on 1 September 1858 to Alois Auer and his wife ...

Siemens & Halske
Siemens & Halske AG (or Siemens-Halske) was a German electrical engineering company that later became part of Siemens. It was founded on 12 October 1847 as ''Telegraphen-Bauanstalt von Siemens & Halske'' by Werner von Siemens and Johann Georg Halske. The company, located in Berlin-Kreuzberg, specialised in manufacturing electrical telegraphs according to Charles Wheatstone's patent of 1837. In 1848, the company constructed one of the first European telegraph lines from Berlin to Frankfurt am Main. Siemens & Halske was not alone in the realm of electrical engineering. In 1887, Emil Rathenau had established ''Allgemeine Elektrizitäts-Gesellschaft'' (AEG), which became a long-time rival. In 1881, Siemens & Halske built the Gross-Lichterfelde Tramway, the world's first electric streetcar line, in the southwestern Lichterfelde suburb of Berlin, followed by the Mödling and Hinterbrühl Tram near Vienna, the first electrical interurban tram in Austria-Hungary. 1882 saw the openi ...

Tungsten
Tungsten, or wolfram, is a chemical element with the symbol W and atomic number 74. Tungsten is a rare metal found naturally on Earth almost exclusively as compounds with other elements. It was identified as a new element in 1781 and first isolated as a metal in 1783. Its important ores include scheelite and wolframite, the latter lending the element its alternate name. The free element is remarkable for its robustness, especially the fact that it has the highest melting point of all known elements barring carbon (which sublimes at normal pressure), melting at . It also has the highest boiling point, at . Its density is , comparable with that of uranium and gold, and much higher (about 1.7 times) than that of lead. Polycrystalline tungsten is an intrinsically brittle and hard material (under standard conditions, when uncombined), making it difficult to work. However, pure single-crystalline tungsten is more ductile and can be cut with a hard-steel hacksaw. Tungsten occurs in many ...

Osmium
Osmium (from Greek grc, ὀσμή, osme, smell, label=none) is a chemical element with the symbol Os and atomic number 76. It is a hard, brittle, bluish-white transition metal in the platinum group that is found as a trace element in alloys, mostly in platinum ores. Osmium is the densest naturally occurring element. When experimentally measured using X-ray crystallography, it has a density of . Manufacturers use its alloys with platinum, iridium, and other platinum-group metals to make fountain pen nib tipping, electrical contacts, and in other applications that require extreme durability and hardness. Osmium is among the rarest elements in the Earth's crust, making up only 50 parts per trillion ( ppt). It is estimated to be about 0.6 parts per billion in the universe and is therefore the rarest precious metal. Characteristics Physical properties Osmium has a blue-gray tint and is the densest stable element; it is approximately twice as dense as lead and narrowly denser tha ...

Third Reich
Nazi Germany (lit. "National Socialist State"), ' (lit. "Nazi State") for short; also ' (lit. "National Socialist Germany") (officially known as the German Reich from 1933 until 1943, and the Greater German Reich from 1943 to 1945) was the German state between 1933 and 1945, when Adolf Hitler and the Nazi Party controlled the country, transforming it into a dictatorship. Under Hitler's rule, Germany quickly became a totalitarian state where nearly all aspects of life were controlled by the government. The Third Reich, meaning "Third Realm" or "Third Empire", alluded to the Nazi claim that Nazi Germany was the successor to the earlier Holy Roman Empire (800–1806) and German Empire (1871–1918). The Third Reich, which Hitler and the Nazis referred to as the Thousand-Year Reich, ended in May 1945 after just 12 years when the Allies defeated Germany, ending World War II in Europe.
