Oskar Von Miller
Oskar Franz Xaver Miller, since 1875 von Miller (7 May 1855 – 9 April 1934), was a German engineer and founder of the Deutsches Museum, a large museum of technology and science in Munich. Biography Born in Munich into an Upper Bavarian family from Aichach, he was the son of the first supervisor of the royal ore foundry in Munich, Ferdinand von Miller (1813–1887) and his wife Anna Pösl (1815–1890). Miller married the painter Marie Seitz in 1884, with whom he had seven children, two of whom died in infancy. His brother was the ore caster and director of the Munich Academy of Fine Arts Baron Ferdinand von Miller. With the elevation of his father Ferdinand into the Bavarian nobility on 12 October 1875 and with the inscription of the family name on the roll of the aristocracy of the Kingdom of Bavaria on 30 December 1875, Oskar was simultaneously ennobled. Miller decided to study technology and civil engineering at the Technische Hochschule München. Soon he discovered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mikhail Dolivo-Dobrovolsky
Mikhail Osipovich Dolivo-Dobrovolsky (; or ''Michail Ossipowitsch Doliwo-Dobrowolski''; – ) was a Russian-born engineer, electrician, and inventor of Polish-Russian origins, active in the German Empire and also in Switzerland. After studying in Germany and while working in Berlin for ''Allgemeine Elektricitäts-Gesellschaft'' (AEG), he became one of the founders (the others were Nikola Tesla, Galileo Ferraris and Jonas Wenström) of polyphase electrical systems, developing the three-phase electrical generator and a three-phase electrical motor (1888) and studying star and delta connections. The triumph of the three-phase system was displayed in Europe at the International Electro-Technical Exhibition of 1891, where Dolivo-Dobrovolsky used this system to transmit electric power at the distance of 176 km with 75% efficiency. In 1891 he also created a three-phase transformer and short-circuited ( squirrel-cage) induction motor. He designed the world's first three-ph ...

Holzkirchen, Upper Bavaria
Holzkirchen is a market town in Bavaria, Germany. With a population of over 16,000 (2008) it is the largest town in the Miesbach district. Holzkirchen is located on the Alpenvorland in the county of Miesbach. History Holzkirchen was established as a Markt in the 13th century. Holzkirchen was the location of one of the main transmitting stations for Radio Free Europe. Transmissions started in 1951 and provided the people of Eastern Europe with news from Western Europe. The transmitters had a strength of up to 135 Kilowatts and was upgraded to 150 Kilowatts in 1967. The relay transmitters were decommissioned in 1990. Final decommissioning of the Holzkirchen array was in 2004. There were claims that the high-powered transmissions caused illnesses locally . There were also claims that it was so strong that locals could hear the radio programmes through their faucets . Subsequent to the relocation of RFE studios from Munich to Prague, the medium wave transmitter was shut down in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Walchensee Hydroelectric Power Station
The Walchensee Power Plant () is a hydroelectric power station in Bavaria, Germany. It is a storage power station that is fed water from the Walchensee which is then released into the Kochelsee. The installed capacity is 124 MW with an annual production of 300 GWh. The power plant is south of Kochelsee, about from the village of Walchensee. It is one of the largest of its kind in Germany and has been owned by Uniper Kraftwerke GmbH since 2016. Technical operation The power station uses the hydraulic head of about between the Walchensee (acting as the upper reservoir, at above sea level) and the Kochelsee ( a.s.l.) to generate electricity. Through six, ducts connecting the two natural lakes, the water flows to the hydro-electric plant's four Pelton water turbines with single-phase generators, and four Francis water turbines with three-phase generators, and then exits into the Kochelsee. Because the water level constantly changes, neither lake fully freezes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Carl Von Linde
Carl Paul Gottfried von Linde (11 June 1842 – 16 November 1934) was a German scientist, engineer, and businessman. He discovered the refrigeration cycle and invented the first industrial-scale air separation and gas liquefaction processes, which led to the first reliable and efficient compressed-ammonia refrigerator in 1876. Linde was the founder of the company now known as Linde plc but formerly known (variously) as the Linde division of Union Carbide, Linde, Linde Air Products, Praxair, and others. This company is the world's largest producer of industrial gases and ushered in the creation of the global supply chain for industrial gases. Linde was a member of scientific and engineering associations, including being on the board of trustees of the Physikalisch-Technische Reichsanstalt and the Bavarian Academy of Sciences and Humanities. He was knighted in 1897 as Ritter von Linde. Biography Early years Born in , Bavaria as the son of a German-born minister and a ...

Hugo Junkers
Hugo Junkers (3 February 1859 – 3 February 1935) was a German aircraft engineer and aircraft designer who pioneered the design of all-metal airplanes and flying wings. His company, Junkers Flugzeug- und Motorenwerke AG (Junkers Aircraft and Motor Works), was one of the mainstays of the German aircraft industry in the years between World War I and World War II. His multi-engined, all-metal passenger and freight planes helped establish airlines in Germany and around the world. In addition to aircraft, Junkers also built both diesel and petrol engines and held various thermodynamic and metallurgical patents. He was also one of the main sponsors of the Bauhaus movement and facilitated the move of the Bauhaus from Weimar to Dessau (where his factory was situated) in 1925. Amongst the highlights of his career were the Junkers J 1 of 1915, the world's first practical all-metal aircraft, incorporating a cantilever wing design with virtually no external bracing, the Junkers F ...

Max Planck
Max Karl Ernst Ludwig Planck (; ; 23 April 1858 – 4 October 1947) was a German Theoretical physics, theoretical physicist whose discovery of energy quantum, quanta won him the Nobel Prize in Physics in 1918. Planck made many substantial contributions to theoretical physics, but his fame as a physicist rests primarily on his role as the originator of Quantum mechanics, quantum theory and one of the founders of modern physics, which revolutionized understanding of atomic and Subatomic particle, subatomic processes. He is known for the Planck constant, which is of foundational importance for quantum physics, and which he used to derive a set of Unit of measurement, units, today called Planck units, expressed only in terms of fundamental physical constants. Planck was twice president of the German scientific institution Kaiser Wilhelm Society. In 1948, it was renamed the Max Planck Society (Max-Planck-Gesellschaft) and nowadays includes 83 institutions representing a wide range ...

Lauffen
Lauffen am Neckar (, ) or simply Lauffen is a town in the district of Heilbronn, Baden-Württemberg, Germany. It is on the river Neckar, southwest of Heilbronn. The town is famous as the birthplace of the poet Friedrich Hölderlin and for its quality wines – in particular the "Lauffener Katzenbeißer Schwarzriesling". Geography Lauffen is located in the southern part of the district of Heilbronn, south of Heilbronn and north of the capital of Baden-Württemberg, Stuttgart, on the Neckar. The small river Zaber flows into the Neckar at this point. The neck of the previous great bow in the course of the north-flowing Neckar was broken through by erosion somewhere between 400 BC and 100 BC and for several centuries the watercourse survived as a ring of lakes. The old circular riverbed is now dry, apart from one small artificial lake. Along the old riverbed, a round hill was formed – its slopes now partially covered by the Kaywald forest and with other areas given over to th ...
