Leopold Auerbach
Leopold Auerbach (27 April 1828 – 30 September 1897) was a Jewish German anatomy, anatomist and neuropathology, neuropathologist born in Breslau. He is best known for discovering the myenteric plexus aka Auerbach's plexus, which helps control the GI tract. Education and career Auerbach studied medicine at the Universities of University of Breslau, Breslau, University of Berlin, Berlin and the University of Leipzig, Leipzig. He became a physician in 1849, obtained his habilitation in 1863. From 1872 he was an associate professor of neuropathology at the University of Breslau. Discoveries Auerbach was among the first physicians to diagnose the nervous system using histology, histological staining methods. He published a number of papers on neuropathological problems and muscle-related disorders.

Gas Mantle
A Coleman white gas lantern mantle glowing at full brightness An incandescent gas mantle, gas mantle or Welsbach mantle is a device for generating bright white light when heated by a flame. The name refers to its original heat source in gas lights which illuminated the streets of Europe and North America in the late 19th century. ''Mantle'' refers to the way it hangs like a cloak above the flame. Gas mantles are also used in some portable camping lanterns, pressure lanterns and some oil lamps. Gas mantles are usually sold as a fabric bag which, because of impregnation with metal nitrates, burns away to leave a rigid but fragile mesh of metal oxides when heated during initial use; these metal oxides produce light from the heat of the flame whenever used. Thorium dioxide was commonly a major component; being radioactive, it has led to concerns about the safety of those involved in manufacturing mantles. Normal use, however, poses minimal health risk.

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 ...

Peter Cooper Hewitt
Peter Cooper Hewitt (May 5, 1861 – August 25, 1921) was an American electrical engineer and inventor, who invented the first mercury-vapor lamp in 1901. Hewitt was issued on September 17, 1901. In 1903, Hewitt created an improved version that possessed higher color qualities which eventually found widespread industrial use. Early life Hewitt was born in New York City, the son of New York City Mayor Abram Hewitt and the grandson of Business magnate, industrialist Peter Cooper. He was educated at the Stevens Institute of Technology and the Columbia School of Engineering and Applied Science, Columbia University School of Mines. Career In 1901, Hewitt invented and patented a mercury-vapor lamp that was the forerunner of the fluorescent lamp. A gas-discharge lamp, Hewitt's invention used Mercury (element), mercury vapor produced by passing current through liquid mercury. His first lamps had to be started by tilting the tube to make contact between the two electrodes and th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mercury-vapor Lamp
A mercury-vapor lamp is a gas-discharge lamp that uses an electric arc through vaporized mercury to produce light. The arc discharge is generally confined to a small fused quartz arc tube mounted within a larger soda lime or borosilicate glass bulb. The outer bulb may be clear or coated with a phosphor; in either case, the outer bulb provides thermal insulation, protection from the ultraviolet radiation the light produces, and a convenient mounting for the fused quartz arc tube. Mercury-vapor lamps are more energy efficient than incandescent lamps with luminous efficacies of 35 to 55 lumens/watt. Their other advantages are a long bulb lifetime in the range of 24,000 hours and a high-intensity light output. For these reasons, they are used for large area overhead lighting, such as in factories, warehouses, and sports arenas as well as for streetlights. Clear mercury lamps produce a greenish light due to mercury's combination of spectral lines. This is not flattering to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leo Arons
Martin Leo Arons (15 February 1860 – 10 October 1919) was a German physicist and social democratic politician. He was the namesake of the ''Lex Arons'', a law which disallowed members of the Social Democratic Party of Germany (, SPD) to teach at Prussian universities. Life and work Leo Arons came from a wealthy Jewish banking family in Berlin. His parents were Albert Arons (1826–1897), a partner in the prestigious private banking house ''Gebrüder Arons'', and Clara Goldschmidt (1837–1867). In 1887 Leo Arons married Johanna Bleichröder (1861–1938), a daughter of the banker Julius Bleichröder (1828–1907). Arons' brother, the banker Paul Arons (1861–1932), married Johanna's sister Gertrude (1865–1917) a few years later. After taking his ''Abitur'', Leo Arons studied chemistry and physics, earning a doctorate degree in Strasbourg in 1888. As a scientist he worked in the area of experimental physics. He developed the mercury vapor lamp (also called "Arons' tub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manfred Von Ardenne
Manfred baron von Ardenne (; 20 January 190726 May 1997) was a German researcher, autodidact in applied physics, and an inventor. He took out approximately 600 patents in fields including electron microscopy, medical technology, nuclear technology, plasma physics, and radio and television technology. From 1928 to 1945, he directed his self-funded and private research laboratory ''Forschungslaboratorium für Elektronenphysik'', where he developed and invented many techniques used in modern physics.

Gyrocompass
A gyrocompass is a type of non-magnetic compass which is based on a fast-spinning disc and the rotation of the Earth (or another planetary body if used elsewhere in the universe) to find geographical Direction (geometry), direction automatically. A gyrocompass makes use of one of the seven fundamental ways to determine the heading of a vehicle. A gyroscope is an essential component of a gyrocompass, but they are different devices; a gyrocompass is built to use the effect of gyroscopic precession, which is a distinctive aspect of the general gyroscopic effect. Gyrocompasses, such as the fibre optic gyrocompass are widely used to provide a heading for navigation on ships. This is because they have two significant advantages over magnetic compasses: * they find true north as determined by the axis of the Earth's rotation, which is different from, and navigationally more useful than, Magnetic North Pole#Magnetic north and magnetic declination, ''magnetic'' north, and * they have a ...

Hermann Anschütz-Kaempfe
Hermann Franz Joseph Hubertus Maria Anschütz-Kaempfe (3 October 1872 – 6 May 1931) was a German art historian and inventor. He was born in Zweibrücken and died in Munich. In his quest to navigate to the North Pole by submarine, he became interested in the concept of the gyrocompass. In 1905 he founded, with Friedrich Treitschke, the company Anschütz & Co (today Anschütz GmbH) in Kiel, Germany. Anschütz was the first firm to manufacture gyroscopic navigation instruments, which Anschütz-Kaempfe designed. One of his staff was Maximilian Schuler, who made the fundamental discovery of Schuler tuning.
