Henri Tudor
Henri Owen Tudor (30 September 1859 – 31 May 1928) was a Luxembourg engineer, inventor, and industrialist. He developed the first commercially usable lead-acid battery. Life Henri Tudor was the son of John Thomas Tudor from Llanarth (United Kingdom) and Marie Loser from Rosport. He attended the primary and secondary school as a boarder at the municipal College of Chimay (Belgium), and was a student from 1879 to 1883 at the École Polytechnique, which was part of Brussels University. In 1885, the young engineer specialised at an electrical engineering institution in Paris, where he attended the lectures given by Marcel Deprez. Henri Tudor was interested in electricity and especially in its storage. He developed an electric lighting system in his father's residence, the ''Irminenhof'' in Rosport, even before he had completed his engineering studies. During his vacations, he connected a Gramme type generator to the water-wheel of the ''Bannmillen'', a mill located on the lo ...

Luxembourgers
Luxembourgers ( ; lb, Lëtzebuerger ) are a Germanic ethnic group and nation native to their nation state of Luxembourg, where they make up around half of the population. They share the culture of Luxembourg and speak Luxembourgish. Luxembourgers were, much like Austrians, historically considered to be a regional subgroup of ethnic Germans and viewed themselves as such until the collapse of the German Confederation. Luxembourg became independent, while remaining in personal union with the Netherlands, after the signing of the Treaty of London in 1839. The personal union proved short-lived as it was bilaterally and amicably dissolved in 1890.Cole (2011), p. 246 Legally, all citizens of the Grand Duchy of Luxembourg are considered to be ''Luxembourgers'' per Luxembourgish law, although a distinct Germanic ethnolinguistic identification is vocally espoused and promoted. The corresponding adjective is "Luxembourgish". Location Most ethnic Luxembourgers live in the Grand Duchy o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Varta
VARTA AG (; german: link=no, Vertrieb, Aufladung, Reparatur transportabler Akkumulatoren – ) is a German company manufacturing batteries for global automotive, industrial, and consumer markets. History VARTA was founded by Adolf Müller in 1887, and established in 1904 as a subsidiary of Accumulatoren-Fabrik AFA. After World War I, VARTA together with AFA was acquired by German industrialist Günther Quandt and Industrialist and VARTA CEO Dr. Carl Hermann Roderbourg.

Electrodes
An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit (e.g. a semiconductor, an electrolyte, a vacuum or air). Electrodes are essential parts of batteries that can consist of a variety of materials depending on the type of battery. The electrophore, invented by Johan Wilcke, was an early version of an electrode used to study static electricity. Anode and cathode in electrochemical cells Electrodes are an essential part of any battery. The first electrochemical battery made was devised by Alessandro Volta and was aptly named the Voltaic cell. This battery consisted of a stack of copper and zinc electrodes separated by brine-soaked paper disks. Due to fluctuation in the voltage provided by the voltaic cell it wasn't very practical. The first practical battery was invented in 1839 and named the Daniell cell after John Frederic Daniell. Still making use of the zinc–copper electrode combination. Since then many more batteries have be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
