René Barthélemy
René Barthélemy (10 March 1889 – 12 February 1954) was a French engineer and a pioneer in the development of television. Background The invention of television was a slow enterprise of collective improvement between researchers and do-it-yourselfers from different countries, the first concepts of which date back to the end of the 1870s. It was the successive discoveries in electricity and optics that made it possible to formulate the theoretical projects, the first experiments and the first demonstrations. Biography Barthélemy was the son of a tailor from Nangis, and his teachers encouraged him to continue his studies in engineering in which during 1909–1910 he studied for a diploma from the École Supérieure d'Électricité. At 22 years old he was a radio-telegraphist at the Eiffel Tower. In 1922 he filed a patent on mains power supply for radio receivers for which, until then, heavy and bulky batteries were used; his invention assisted the development of radio bro ...

René Barthélemy C
René (''born again'' or ''reborn'' in French) is a common first name in French-speaking, Spanish-speaking, and German-speaking countries. It derives from the Latin name Renatus. René is the masculine form of the name (Renée being the feminine form). In some non-Francophone countries, however, there exists the habit of giving the name René (sometimes spelled without an accent) to girls as well as boys. In addition, both forms are used as surnames (family names). René as a first name given to boys in the United States reached its peaks in popularity in 1969 and 1983 when it ranked 256th. Since 1983 its popularity has steadily declined and it ranked 881st in 2016. René as a first name given to girls in the United States reached its peak in popularity in 1962 when it ranked 306th. The last year for which René was ranked in the top 1000 names given to girls in the United States was 1988. Persons with the given name * René, Duke of Anjou (1409–1480), titular king of Naples a ...

Académie Des Sciences (France)
The French Academy of Sciences (French: ''Académie des sciences'') is a learned society, founded in 1666 by Louis XIV at the suggestion of Jean-Baptiste Colbert, to encourage and protect the spirit of French scientific research. It was at the forefront of scientific developments in Europe in the 17th and 18th centuries, and is one of the earliest Academies of Sciences. Currently headed by Patrick Flandrin (President of the Academy), it is one of the five Academies of the Institut de France. History The Academy of Sciences traces its origin to Colbert's plan to create a general academy. He chose a small group of scholars who met on 22 December 1666 in the King's library, near the present-day Bibliothèque Nationals, and thereafter held twice-weekly working meetings there in the two rooms assigned to the group. The first 30 years of the Academy's existence were relatively informal, since no statutes had as yet been laid down for the institution. In contrast to its Britis ...

Inventors By Nationality
An invention is a unique or novel device, method, composition, idea or process. An invention may be an improvement upon a machine, product, or process for increasing efficiency or lowering cost. It may also be an entirely new concept. If an idea is unique enough either as a stand alone invention or as a significant improvement over the work of others, it can be patented. A patent, if granted, gives the inventor a proprietary interest in the patent over a specific period of time, which can be licensed for financial gain. An inventor creates or discovers an invention. The word ''inventor'' comes from the Latin verb ''invenire'', ''invent-'', to find. Although inventing is closely associated with science and engineering, inventors are not necessarily engineers or scientists. Due to advances in artificial intelligence, the term "inventor" no longer exclusively applies to an occupation (see human computers). Some inventions can be patented. The system of patents was established t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

History Of Television
The concept of television was the work of many individuals in the late 19th and early 20th centuries. The first practical transmissions of moving images over a radio system used mechanical rotating perforated disks to scan a scene into a time-varying signal that could be reconstructed at a receiver back into an approximation of the original image. Development of television was interrupted by the Second World War. After the end of the war, all-electronic methods of scanning and displaying images became standard. Several different standards for addition of color to transmitted images were developed with different regions using technically incompatible signal standards. Television broadcasting expanded rapidly after World War II, becoming an important mass media, mass medium for advertising, propaganda, and entertainment. Television broadcasts can be distributed over the air by VHF and UHF radio signals from terrestrial transmitting stations, by microwave signals from Earth orbi ...

François Mitterrand
François Marie Adrien Maurice Mitterrand (26 October 19168 January 1996) was President of France, serving under that position from 1981 to 1995, the longest time in office in the history of France. As First Secretary of the Socialist Party, he was the first left-wing politician to assume the presidency under the Fifth Republic. Reflecting family influences, Mitterrand started political life on the Catholic nationalist right. He served under the Vichy regime during its earlier years. Subsequently he joined the Resistance, moved to the left, and held ministerial office several times under the Fourth Republic. Mitterrand opposed Charles de Gaulle's establishment of the Fifth Republic. Although at times a politically isolated figure, he outmanoeuvered rivals to become the left's standard bearer in the 1965 and 1974 presidential elections, before being elected president in the 1981 presidential election. He was re-elected in 1988 and remained in office until 1995. Mitterran ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
