Compagnie Générale De La Télégraphie Sans Fil
The Compagnie générale de la télégraphie sans fil (CSF: General Wireless Telegraphy Company) was a French company founded in 1918 during a reorganization and expansion of the Société française radio-électrique (SFR), which became a subsidiary. The company developed technology for radio-telegraphy, radio program transmission, radar, television and other applications. It provided broadcasting and telegraphy services, and sold its equipment throughout the French colonial empire and in many other parts of the world. In 1968 CSF merged with the Thomson-Brandt to form Thomson-CSF. Background From the mid-19th century the world was connected with an increasingly dense network of telegraph wires and submarine cables. In 1887 Heinrich Hertz of Germany conclusively proved the existence of electromagnetic waves. Alexander Stepanovich Popov of Russia developed antennas to transmit and receive radio waves. Scientists such as Édouard Branly and Nikola Tesla also contributed to developme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sainte-Assise Transmitter
The Sainte-Assise transmitter (french: Émetteur de Sainte-Assise) is a very low frequency (VLF) radio transmitter and military installation located on the grounds of the in the communes of Seine-Port, Boissise-la-Bertrand, and Cesson in the Seine-et-Marne department of the Île-de-France region of France. The transmitter's original equipment was inaugurated on 9 January 1921, at the time being the most powerful radio transmitter on Earth. On 26 November 1921 the first French radio program was transmitted from Sainte-Assise. In 1965 the transmitter was used to send VLF signals to FR-1, the first French satellite. Since 1998 the French Navy has used the transmitter to communicate with submerged submarines. Design The original equipment of the Saint-Assise transmitter included large spiral "pancake" inductors in a high-power longwave alternator transmitter which served as a transatlantic wireless telegraphy station. These combinations of inductors and alternator transmitters w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Levallois-Perret
Levallois-Perret () is a commune in the Hauts-de-Seine department and Île-de-France region of north-central France. It lies some from the centre of Paris in the north-western suburbs of the French capital. It is the most densely populated town in Europe and, together with neighbouring Neuilly-sur-Seine, one of the most expensive suburbs of Paris. Name The name Levallois-Perret comes from two housing developments, ''Champerret'' (started by landowner Jean-Jacques Perret in 1822) and ''Village Levallois'' (founded by developer Nicolas-Eugène Levallois in 1845), which resulted in the incorporation of the commune. History On the territory of what is now Levallois-Perret, before the French Revolution, stood the village of Villiers and the hamlet of Courcelles (or La Planchette). They now give their names to two Paris Métro stations.

World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Balkan Wars
The Balkan Wars refers to a series of two conflicts that took place in the Balkan States in 1912 and 1913. In the First Balkan War, the four Balkan States of Greece, Serbia, Montenegro and Bulgaria declared war upon the Ottoman Empire and defeated it, in the process stripping the Ottomans of its European provinces, leaving only Eastern Thrace under the Ottoman Empire's control. In the Second Balkan War, Bulgaria fought against the other four original combatants of the first war. It also faced an attack from Romania from the north. The Ottoman Empire lost the bulk of its territory in Europe. Although not involved as a combatant, Austria-Hungary became relatively weaker as a much enlarged Serbia pushed for union of the South Slavic peoples. The war set the stage for the Balkan crisis of 1914 and thus served as a "prelude to the First World War". By the early 20th century, Bulgaria, Greece, Montenegro and Serbia had achieved independence from the Ottoman Empire, but large eleme ...
