Guglielmo Marconi Guglielmo Marconi was born in Italy in 1874 to a rather wealthy Italian father and Irish mother. He was educated privately and then went to the Livorno Technical Institute. While there, he read an article that grabbed his attention. The article suggested the possibility of using radio waves to communicate without wires.The year was 1894, and the most modern way to send a message was over telegraph wires. (Heinrich Herz, for whom the units hertz and megahertz are named, had discovered and first produced radio waves in 1888.) Marconi jumped right on the problem. He began experimenting at his family's home near Bologna. Within a year he had sent and received signals beyond the range of vision (including over a hill) and then over increasingly great distances up to two miles! He took out a patent in 1896. The Italian government was not interested in Marconi's work, but the British Admiralty was, and it installed Marconi's radio equipment in some of its ships. Radio transmission was pushed to greater and greater lengths, and by 1899, Marconi had sent a signal nine miles across the Bristol Channel and 31 miles across the English Channel to France. Most people believed that the curvature of the earth would prevent sending a signal much farther than 200 miles, so when Marconi was able to transmit across the Atlantic ocean in 1901 , people were stunned. It opened the door to a rapidly developing wireless industry.

G.A.M.T. Gruppo d'Ascolto della Marca Trevigiana GUGLIELMO MARCONI Guglielmo Marconi , (Bologna 1874 - Roma 1937) è stato l' inventore italiano del primo sistema pratico di segnalazione radio. Studiò a Bologna e a Firenze e fin da giovanissimo, intuendo la possibilità di utilizzare le onde elettromagnetiche per inviare segnali a distanza, si interessò di telegrafia senza fili. Verso il 1895, potete consultare anche 100 YEARS OF RADIO - HOME PAGE , dopo numerosi esperimenti realizzati nella villa paterna di Pontecchio, mise a punto un'apparecchiatura con cui riuscì a inviare segnali intelligibili a una distanza di circa 2400 m, usando un'antenna direzionale. Dopo aver brevettato il sistema telegrafico in Gran Bretagna (1896), fondò a Londra la Marconi's Wireless Telegraph and Signal Company, nella quale lavorarono diversi scienziati a un ulteriore perfezionamento dei progetti. real audio G.Marconi voice 1 real audio G.Marconi voice 2 Nel 1899 inviò segnali radio in Francia attraverso la Manica e nel 1901 realizzò la prima comunicazione attraverso l'oceano Atlantico tra Poldhu, in Cornovaglia, e St John's, nell'isola di Terranova (Canada). Il suo sistema fu presto adottato dalle navi britanniche e italiane e, verso il 1907, fu organizzato un regolare servizio pubblico transatlantico di telegrafia senza fili. Nel 1909 Marconi ricevette il premio Nobel per la fisica insieme col fisico tedesco Karl Ferdinand Braun. Durante la prima guerra mondiale fu incaricato di organizzare il servizio italiano di telegrafo senza fili, e in quell'occasione mise a punto la trasmissione a onde corte come mezzo di comunicazione segreta. Proseguì poi gli esperimenti con le onde corte e cortissime e con le microonde, anche in relazione a un loro possibile impiego in medicina. Marconi fu nominato senatore nel 1914 e ricevette il titolo di marchese nel 1929; ottenne inoltre la presidenza del Consiglio nazionale delle ricerche e dell'Accademia d'Italia.

Guglielmo Marconi Il Coesore o Coherer e l'antenna Guglielmo Marconi Coherer: Tipo di coesore Marconi 1894 Coherer rinvenuto nel 1919 in un mucchio di rottami presso la Villa Griffone a Pontecchio. poiche' in quel luogo Marconi negli anni successivi non ebbe piu' occasione di fare soste prolungate, questo coherer deve essere stato da lui costruito, e verosimilmente scartato, prima della sua partenza per l'Inghilterra, all'inizio del 1896. Esso e' del tutto simile ad un secondo esemplare che e' esposto in un museo di Stoccolma con l'indicazione (Coherer di Marconi del 1896) e che e' stato effettivamente usato. Il piccolo rivelatore, che una delle due figure riproduce ingrandito, ha reofori saldati sul vetro e all'interno elettrodi d'argento con una piccola quantita' di limatura, che non presentano rivelanti ossidazioni. Il coherer, della lunghezza di un paio di centimetri, e' montato su di un frammento di tubo di vetro di notevole spessore che funge da supporto, rigido e isolante. Notare la mancanza del codolo per evacuare l'aria prima della chiusura alla fiamma.

Guglielmo Marconi (for a list of items in the collection click here (for a description of "MARCONI IN LONDON" book click here Guglielmo MARCONI did not, of course, "invent" radio. Nobody ever does invent anything from scratch as each "invention" is the consequence of many previous discoveries and researches (in this case especially those done by Faraday, Maxwell, Hertz, Lodge, Righi and Tesla). Besides he can only be regarded as having "invented" (in 1896) wireless telegraphy as radio, as we know it, only became possible with the invention of the amplifying valve (1906) and the possibility of modulating a signal over a carrier wave (which happened later). However he must be considered as the most important single person who contributed in a decisive way to take the "invention" out of the laboratories and put it in everybody's life. In this sense he is really the "inventor" of a new way of thinking and of transmitting intelligence. Radio has really changed this century and the way we all think and relate. Marconi had a vision and managed to realize it against all odds. He is, perhaps, one of the last "romantic" inventors in that, as public belief likes to portray inventors, he battled against nature's difficulties and human prejudices making his success a true epic adventure. His popularity (notwithstanding his fascist role) is assured in history by his conforming to what people expect from a hero and an inventor.

Guglielmo Marconi Guglielmo Marconi Italian physicist and inventor of a successful system of radio telegraphy (1896). In 1909 he received the Nobel Prize for Physics, which he shared with German physicist Ferdinand Braun. He later worked on the development of shortwave wireless communication, which constitutes the basis of nearly all modern long-distance radio. Education and early work. Marconi's father was Italian and his mother Irish. Educated first in Bologna and later in Florence, Marconi then went to the technical school in Leghorn, where, in studying physics, he had every opportunity for investigating electromagnetic wave technique, following the earlier mathematical work of James Clerk Maxwell and the experiments of Heinrich Hertz, who first produced and transmitted radio waves, and Sir Oliver Lodge, who conducted research on lightning and electricity. Receiving little encouragement to continue his experiments in Italy, he went, in 1896, to London, where he was soon assisted by Sir William Preece, the chief engineer of the post office. Marconi filed his first patent in England in June 1896 and, during that and the following year, gave a series of successful demonstrations, in some of which he used balloons and kites to obtain greater height for his aerials. He was able to send signals over distances of up to 6.4 km on the Salisbury Plain and to nearly 14.5 km across the Bristol Channel. These tests, together with Preece's lectures on them, attracted considerable publicity both in England and abroad, and in June 1897 Marconi went to La Spezia, where a land station was erected and communication was established with Italian warships at distances of up to 19 km.

Guglielmo Marconi Born Apr 25 1874 - Died Jul 20 1937 Transmitting Electrical Signals Radio Patent Number(s) 586,193 Inducted 1975 In 1895 Italian inventor Guglielmo Marconi built the equipment and transmitted electrical signals through the air from one end of his house to the other, and then from the house to the garden. These experiments were, in effect, the dawn of practical wireless telegraphy or radio. Following the successes of his experiments at home, Marconi became obsessed with the idea of sending messages across the Atlantic. He built a transmitter, 100 times more powerful than any previous station, at Poldhu, on the southwest tip of England, and in November 1901 installed a receiving station at St. John's Newfoundland. On December 12, 1901, he received signals from across the ocean. News of this achievement spread around the world, and he was acclaimed by outstanding scientists, including Thomas A. Edison. Invention Impact Inventor Bio Marconi was born in Bologna, Italy.His father was Italian, his mother, Irish. He was educated first in Bologna and later in Florence. Then he went to the technical school in Leghorn, where he studied physics.

19. Guglielmo Marconi - Biography guglielmo marconi – Biography. guglielmo marconi was born at Bologna, Italy, on April 25, 1874, the second son of Giuseppe marconi http://www.nobel.se/physics/laureates/1909/marconi-bio.html

Guglielmo Marconi was born at Bologna, Italy, on April 25, 1874, the second son of Giuseppe Marconi, an Italian country gentleman, and Annie Jameson, daughter of Andrew Jameson of Daphne Castle in the County Wexford, Ireland. He was educated privately at Bologna, Florence and Leghorn. Even as a boy he took a keen interest in physical and electrical science and studied the works of Maxwell, Hertz, Righi, Lodge and others. In 1895 he began laboratory experiments at his father's country estate at Pontecchio where he succeeded in sending wireless signals over a distance of one and a half miles. In 1900 he took out his famous patent No. 7777 for "tuned or syntonic telegraphy" and, on an historic day in December 1901, determined to prove that wireless waves were not affected by the curvature of the Earth, he used his system for transmitting the first wireless signals across the Atlantic between Poldhu, Cornwall, and St. John's, Newfoundland, a distance of 2100 miles. Between 1902 and 1912 he patented several new inventions. In 1902, during a voyage in the American liner "Philadelphia", he first demonstrated "daylight effect" relative to wireless communication and in the same year patented his magnetic detector which then became the standard wireless receiver for many years. In December 1902 he transmitted the first complete messages to Poldhu from stations at Glace Bay, Nova Scotia, and later Cape Cod, Massachusetts, these early tests culminating in 1907 in the opening of the first transatlantic commercial service between Glace Bay and Clifden, Ireland, after the first shorter-distance public service of wireless telegraphy had been established between Bari in Italy and Avidari in Montenegro. In 1905 he patented his horizontal directional aerial and in 1912 a "timed spark" system for generating continuous waves.
