Théâtrophone
Théâtrophone ("the theatre phone") was a telephonic distribution system available in portions of Europe that allowed the subscribers to listen to opera and theatre performances over the telephone lines. The théâtrophone evolved from a Clément Ader invention, which was first demonstrated in 1881, in Paris. Subsequently, in 1890, the invention was commercialized by Compagnie du Théâtrophone, which continued to operate until 1932. Origin The origin of the théâtrophone can be traced to a telephonic transmission system demonstrated by Clément Ader at the 1881 International Exposition of Electricity in Paris. The system was inaugurated by the French President Jules Grévy, and allowed broadcasting of concerts or plays. Ader had arranged 80 telephone transmitters across the front of a stage to create a form of binaural stereophonic sound. It was the first two-channel audio system, and consisted of a series of telephone transmitters connected from the stage of the Paris Oper ...

Telephone Newspaper
Telephone Newspapers, introduced in the 1890s, transmitted news and entertainment to subscribers over telephone lines. They were the first example of electronic broadcasting, although only a few were established, most commonly in European cities. These systems predated the development, in the 1920s, of radio broadcasting. They were eventually supplanted by radio stations, because radio signals could more easily cover much wider areas with higher quality audio, without incurring the costs of a telephone line infrastructure. History The introduction of the telephone in the mid-1870s included numerous demonstrations of its use for transmitting musical concerts over various distances. In one particularly advanced example, Clément Ader prepared a listening room at the 1881 Paris Electrical Exhibition, where attendees could listen to performances, in stereo, from the Paris Grand Opera. The concept also appeared in Edward Bellamy's influential 1888 utopian novel, '' Looking Backwar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Exposition Of Electricity
The first International Exposition of Electricity in Paris ran from August 15, 1881 through to November 15, 1881 at the Palais de l'Industrie on the Champs-Élysées. It served to display the advances in electrical technology since the small electrical display at the 1878 Universal Exposition.K. G. Beauchamp, '' Exhibiting electricity'' IET, 1997 , pp.160-165 Exhibitors came from the United Kingdom, United States, Germany, Italy and the Netherlands, as well as from France. As part of the exhibition, the first International Congress of Electricians presented numerous scientific and technical papers, including definitions of the standard practical units volt, ohm and ampere. History Adolphe Cochery, Minister of Posts and Telegraphs of the time, had initially suggested that an international exposition should be held. This show was a great stir. The public could admire the dynamo of Zénobe Gramme, the incandescent light, the Théâtrophone, the electric tramway of Werner vo ...

Clément Ader
Clément Ader (2 April 1841 – 3 May 1925) was a French inventor and engineer who was born near Toulouse in Muret, Haute-Garonne, and died in Toulouse. He is remembered primarily for his pioneering work in aviation. In 1870 he was also one of the pioneers in the sport of cycling in France. Electrical and mechanical inventions Ader was an innovator in both electrical and mechanical engineering. He originally studied electrical engineering, and in 1878 improved on the telephone invented by Alexander Graham Bell. After this he established the telephone network in Paris in 1880. In 1881, he invented the théâtrophone, a system of telephonic transmission where listeners received a separate channel for each ear, enabling stereophonic perception of the actors on a set; it was this invention which gave the first stereo transmission of opera performances, over a distance of 2 miles (3 km) in 1881. In 1903, he devised a V8 engine for the Paris–Madrid race, but although t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stereophonic Sound
Stereophonic sound, or more commonly stereo, is a method of sound reproduction that recreates a multi-directional, 3-dimensional audible perspective. This is usually achieved by using two independent audio channels through a configuration of two loudspeakers (or stereo headphones) in such a way as to create the impression of sound heard from various directions, as in natural hearing. Because the multi-dimensional perspective is the crucial aspect, the term ''stereophonic'' also applies to systems with more than two channels or speakers such as quadraphonic and surround sound. Binaural sound systems are also ''stereophonic''. Stereo sound has been in common use since the 1970s in entertainment media such as broadcast radio, recorded music, television, video cameras, cinema, computer audio, and internet. Etymology The word ''stereophonic'' derives from the Greek (''stereós'', "firm, solid") + (''phōnḗ'', "sound, tone, voice") and it was coined in 1927 by Wester ...

News Program
News broadcasting is the medium of broadcasting various news events and other information via television, radio, or the internet in the field of broadcast journalism. The content is usually either produced locally in a radio studio or television studio newsroom, or by a broadcast network. It may include material such as sports coverage, weather forecasts, traffic reports, political commentary, expert opinions, editorial content, and other material that the broadcaster feels is relevant to their audience. An individual news program is typically reported in a series of individual stories that are presented by one or more anchors. A frequent inclusion is live or recorded interviews by field reporters. Structure, content, and style Television Television news programs inform and discuss current events via the medium of television. A "news bulletin" or a "newscast" are television programs lasting from seconds to hours that provide updates on events. Programs can vary th ...

Iron Clad
An ironclad is a steam-propelled warship protected by iron or steel armor plates, constructed from 1859 to the early 1890s. The ironclad was developed as a result of the vulnerability of wooden warships to explosive or incendiary shells. The first ironclad battleship, , was launched by the French Navy in November 1859 - narrowly pre-empting the British Royal Navy. They were first used in warfare in 1862 during the American Civil War, when ironclads operated against wooden ships and, in a historic confrontation, against each other at the Battle of Hampton Roads in Virginia. Their performance demonstrated that the ironclad had replaced the unarmored ship of the line as the most powerful warship afloat. Ironclad gunboats became very successful in the American Civil War. Ironclads were designed for several uses, including as high seas battleships, long-range cruisers, and coastal defense ships. Rapid development of warship design in the late 19th century transformed the iron ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Centime
Centime (from la, centesimus) is French for "cent", and is used in English as the name of the fraction currency in several Francophone countries (including Switzerland, Algeria, Belgium, Morocco and France). In France, the usage of ''centime'' goes back to the introduction of the decimal monetary system under Napoleon. This system aimed at replacing non-decimal fractions of older coins. A five-centime coin was known as a ''sou'', i.e. a solidus or shilling. In Francophone Canada of a Canadian dollar is officially known as a ''cent'' (pronounced /sɛnt/) in both English and French. However, in practice, the form of ''cenne'' (pronounced /sɛn/) has completely replaced the official ''cent''. Spoken and written use of the official form ''cent'' in Francophone Canada is exceptionally uncommon. In the Canadian French vernacular ''sou'', ''sou noir'' (' means "black" in French), ''cenne'', and ''cenne noire'' are all widely known, used, and accepted monikers when referring to eit ...

Order Of Christ (Portugal)
The Military Order of Christ is the former order of Knights Templar as it was reconstituted in Portugal. Before 1910 it was known as the Royal Military Order of Our Lord Jesus Christ and the Order of the Knights of Our Lord Jesus Christ. It was founded in 1319, with the protection of King Denis of Portugal, after the Templars were abolished on 22 March 1312 by the papal bull, '' Vox in excelso'', issued by Pope Clement V. King Denis refused to pursue and persecute the former knights as had occurred in most of the other sovereign states under the political influence of the Catholic Church. Heavily swayed by Philip IV of France, Pope Clement had the Knights Templar annihilated throughout France and most of Europe on charges of heresy, but Denis revived the Templars of Tomar as the Order of Christ, largely for their aid during the ''Reconquista'' and in the reconstruction of Portugal after the wars. Denis negotiated with Clement's successor, John XXII, for recognition of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marcel Proust
Valentin Louis Georges Eugène Marcel Proust (; ; 10 July 1871 – 18 November 1922) was a French novelist, critic, and essayist who wrote the monumental novel '' In Search of Lost Time'' (''À la recherche du temps perdu''; with the previous English title translation of ''Remembrance of Things Past''), originally published in French in seven volumes between 1913 and 1927. He is considered by critics and writers to be one of the most influential authors of the 20th century. Background Proust was born on 10 July 1871 at the home of his great-uncle in the Paris Borough of Auteuil (the south-western sector of the then-rustic 16th arrondissement), two months after the Treaty of Frankfurt formally ended the Franco-Prussian War. His birth took place at the very beginning of the Third Republic, during the violence that surrounded the suppression of the Paris Commune, and his childhood corresponded with the consolidation of the Republic. Much of '' In Search of Lost Time'' concerns t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
