Siemens-Ring
The Werner von Siemens Ring (in German orthography, Werner-von-Siemens-Ring) is one of the highest awards for technical sciences in Germany. It has been awarded from 1916 to 1941 and since 1952 about every three years by the foundation ''Stiftung Werner-von-Siemens-Ring''. The foundation was established on 13 December 1916 on the occasion of the 100th anniversary of the birth of Werner von Siemens. It is located in Berlin and is traditionally managed by the '' Deutscher Verband Technisch-Wissenschaftlicher Vereine'' (DVT) (English: German Federation of Technical and Scientific Associations). Before 1960, the name of the award had been simply Siemens Ring (German Siemens-Ring or Siemensring). The award is presented as a golden ring with emeralds and rubies depicting the leaves and fruit of laurel, placed in an individually crafted cassette carrying the portrait of Werner von Siemens and the dedication to the recipient. According to the statutes, patron of the foundation council is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carl Bosch
Carl Bosch (; 27 August 1874 – 26 April 1940) was a German chemist and engineer and Nobel Laureate in Chemistry.

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 ...

Wolfgang Gaede
Wolfgang Max Paul Gaede (25 May 1878 – 24 June 1945) was a German physicist and pioneer of vacuum engineering. Life Gaede was born in Lehe, Bremerhaven, the son of Prussian Colonel Karl Gaede and Amalia, nee Renf. In 1897 he began studying medicine at the University of Freiburg, but he soon switched to the field of physics. In 1901 he wrote his doctoral thesis on the change of the specific heat of metals with temperature. Subsequent research on the Volta effect in a vacuum was unsuccessful, as the pump technology of the time could not create sufficient vacuum for the investigations. This prompted Gaede to deal more closely with vacuum technology. He invented the rotating mercury pump for high vacuum, which he presented to his scientific colleagues in 1905 at a congress in Merano. Also in Freiburg im Breisgau, Gaede wrote his habilitation thesis on ''The external friction of gases'' in 1909. In 1913 he received a professorship at the University of Freiburg. In the fo ...

German Orthography
German orthography is the orthography used in writing the German language, which is largely phonemic. However, it shows many instances of spellings that are historic or analogous to other spellings rather than phonemic. The pronunciation of almost every word can be derived from its spelling once the spelling rules are known, but the opposite is not generally the case. Today, Standard High German orthography is regulated by the (Council for German Orthography), composed of representatives from most German-speaking countries. Alphabet The modern German alphabet consists of the twenty-six letters of the ISO basic Latin alphabet plus four special letters. Basic alphabet 1in Germany 2in Austria Special letters German has four special letters; three are vowels accented with an umlaut () and one is a ligature of and (; called "ess-zed/zee" or "sharp s"), all of which are officially considered distinct letters of the alphabet, and have their own names separate fr ...

Konrad Zuse
Konrad Ernst Otto Zuse (; 22 June 1910 – 18 December 1995) was a German civil engineer, pioneering computer scientist, inventor and businessman. His greatest achievement was the world's first programmable computer; the functional program-controlled Turing-complete Z3 became operational in May 1941. Thanks to this machine and its predecessors, Zuse has often been regarded as the inventor of the modern computer. Zuse was noted for the S2 computing machine, considered the first process control computer. In 1941, he founded one of the earliest computer businesses, producing the Z4, which became the world's first commercial computer. From 1943 to 1945 he designed Plankalkül, the first high-level programming language. In 1969, Zuse suggested the concept of a computation-based universe in his book (''Calculating Space''). Much of his early work was financed by his family and commerce, but after 1939 he was given resources by the government of Nazi Germany.
