Hugo Güldner
Carl Hugo Güldner (18 July 1866 – 12 March 1926) was a German engineer and inventor. He is best known for inventing the two-stroke diesel engine, and the Valve_timing#Valve_overlap, valve overlap in internal combustion engines. Life and career Güldner was born in Herdecke, south of Dortmund. He attended the ''Höhere Maschinenbauschule'' (mechanical engineering college) in Hagen, and worked as an engineer in Magdeburg throughout the 1890s. In 1891, Güldner married Adele Benecke, with whom he had two sons and two daughters.Allen D. Gebus: ''World Who's who in Science: A Biographical Dictionary of Notable Scientists from Antiquity to the Present'', Marquis-Who's Who, 1968, p. 719 In Magdeburg, Güldner invented several devices related to internal combustion engines, and he also worked as an editor for the "Der Monteur" magazine. In 1894, Güldner contracted with the Schumann & Küchler factory in Erfurt; however, they never built any engines or devices based upon Güldner's ...

Herdecke
Herdecke () is a town in the district of Ennepe-Ruhr-Kreis, North Rhine-Westphalia in Germany. It is located south of Dortmund in the Ruhr Area. Its location between the two Ruhr (river), Ruhr reservoirs Hengsteysee and Harkortsee has earned it the nickname ''Die Stadt zwischen den Ruhrseen'' (lit. ''The city between the Ruhr lakes''). The city is located in the area of the Regionalverband Ruhr (RVR). The two Ruhr lakes as well as the forests on the Ardey heights make the town attractive to tourists. The historic center with its many half timbered houses and the 30-metre-high railway viaduct across the Ruhr valley are two more landmarks. Geography Herdecke is located at the foot of the Ardeygebirge, the northwestern part of the Sauerland, between Dortmund in the North and Northeast, Hagen in the South, Wetter (Ruhr) in the Southwest and Witten (Germany), Witten in the West and Northwest. Herdecke lies between 80 and 274 meters above sea levels. It lies on the north bank of the r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Imanuel Lauster
Imanuel Lauster (28 January 1873 – 15 March 1948) was a German engineer and businessman, who worked for Rudolf Diesel and drew up Diesel’s design for the first Diesel engine, Motor 250/400. He also served as the head of M.A.N.'s board of directors from 1932 to 1934. Life and career Lauster was born in , a small municipality then just to the north-east of Stuttgart (into which it was subsumed in 1923). He lived a youth "full of privation". On 1 April 1888, he joined ''Gottlieb Kuhn Maschinen- und Kesselfabrik'' in Stuttgart-Berg. The firm's workshop did not need fitter apprentices at the time, therefore, Lauster was taught technical drawing at the design bureau before he started working as a fitter at the workshop in 1889. Later, Lauster also assembled steam engines, and tested them on a dynamometer. In 1891, Lauster was assigned to the newly founded internal combustion engine workshop of ''G. Kuhn'', where he had to build 6 PS and 8 PS Langensiepen engines with glow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
19th-century German Engineers
The 19th century began on 1 January 1801 (represented by the Roman numerals MDCCCI), and ended on 31 December 1900 (MCM). It was the 9th century of the 2nd millennium. It was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanded beyond its British homeland for the first time during the 19th century, particularly remaking the economies and societies of the Low Countries, France, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Catholic Church, in response to the growing influence and power of modernism, secularism and materialism, formed the First Vatican Council in the late 19th century to deal with such problems and con ...

1926 Deaths
In Turkey, the year technically contained only 352 days. As Friday, December 18, 1926 ''(Julian Calendar)'' was followed by Saturday, January 1, 1927 '' (Gregorian Calendar)''. 13 days were dropped to make the switch. Turkey thus became the last country to officially adopt the Gregorian Calendar, which ended the 344-year calendrical switch around the world that took place in October, 1582 by virtue of the Papal Bull made by Pope Gregory XIII.

Moritz Schröter
Maximilian Moritz Schröter (25 February 1851 – 12 March 1925) was a German industrial engineer and university professor of thermodynamics and the theory of machines. Life and career Moritz Schröter was the son of Moritz Schröter, who himself was a university professor. After his father′s death in 1867, Gustav Zeuner became the guardian of 16-year-old Schröter. After finishing the Gymnasium in Zürich, Schröter studied at the '' Polytechnikum Zürich'', where he was awarded a diploma in engineering. From 1873 to 1876 he worked in the locomotive factory ''Georg Sigl'' in Wiener Neustadt. He then returned to Zürich, to become the university assistant of Georg Veith. In 1879, Schröter became a professor of theory of machines at the Technical University of Munich, where he built a new laboratory for machine design. From 1908 to 1911, he was the university's rector. Schröter helped designing four important machines in engineering history: the refrigerator (1887), the st ...

Motor 250/400
The Motor 250/400 is the first functional diesel engine. It was designed by Rudolf Diesel, and drawn by Imanuel Lauster. The workshop of the Maschinenfabrik Augsburg built two units, the ''A-Motor'', and the ''B-Motor''. The latter has been on static display at the Deutsches Museum in Munich since testing it came to an end. Throughout the late 1890s, several licensed copies of the ''Motor 250/400'' were made. Most of these copies were very unreliable, which almost caused the diesel engine's demise. History Development In early 1893, Rudolf Diesel had contracted with both Maschinenfabrik Augsburg and Krupp in Essen to develop an engine based on his essay Theory and Construction of a Rational Heat Motor. However, by mid-1893 Diesel had realised that the rational heat motor would not work, and he modified his design. This modified design would later be known as the diesel engine. The first prototype, ''Motor 150/400'', was completed on 12 July 1893. Initial tests with it prove ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Friedrich Sass
Friedrich Sass (6 January 1883 – 26 February 1968) was a German engineer, university professor and historian. Life and career Friedrich Sass was born in Koldenbüttel and attended the ''Gymnasium'' (grammar school) in Schleswig. He studied mechanical engineering at the Technical University of Munich, and marine engineering at Technische Universität Berlin. After graduating from TU Berlin, Sass worked as a steam turbine designer at AEG from 1908. During World War I, Sass became the head of AEG's Diesel engine department, where he designed the double-acting piston two-stroke Diesel engine with air-blast-less, direct fuel injection; initially, it was intended for submarine use. In the 1920s, Sass continued his work on direct fuel injection systems; he was the first engineer to study the relation between the diameter of a fuel spray at the point of injection, and its cylinder intrusion. In 1940, Sass stopped working for AEG. From 1927, Sass had been an untenured professor at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kingdom Of Prussia
The Kingdom of Prussia (, ) was a German state that existed from 1701 to 1918.Marriott, J. A. R., and Charles Grant Robertson. ''The Evolution of Prussia, the Making of an Empire''. Rev. ed. Oxford: Clarendon Press, 1946. It played a significant role in the unification of Germany in 1871 and was a major constituent of the German Empire until its German Revolution of 1918–1919, dissolution in 1918. Although it took its name from the Prussia (region), region called Prussia, it was based in the Margraviate of Brandenburg. Its capital was Berlin. The list of monarchs of Prussia, kings of Prussia were from the House of Hohenzollern. The polity of Brandenburg-Prussia, predecessor of the kingdom, became a military power under Frederick William, Elector of Brandenburg, known as "The Great Elector". As a kingdom, Prussia continued its rise to power, especially during the reign of Frederick the Great, Frederick II "the Great".Horn, D. B. "The Youth of Frederick the Great 1712–30." ...
