The First Electronic Church of America Guglielmo Marconi In the first year of the 20th century, a well-tailored young man of 27 named Guglielmo Marconi sat in a shack on a cliff in Newfoundland trying to receive a message on his new invention, the wireless telegraph. The significant thing about the message was not the message itself, but its origin. It was being sent to him all the way across the Atlantic on electromagnetic waves generated by one of his confederates in Cornwall, England. It was history's first long distance wireless radio communication. But, on a blustery December 12, 1901, Marconi and his assistants heard the faint transmission from across the Atlantic: dot, dot, dot. The letter S. In the short history of electronic communications, there may have never been a more important day, or a more important discovery. The wireless telegraph was then a toddler, no more than six years old. But up until then, scientists and engineers were unanimous in their belief: you couldn't send a wireless message over the earth's horizon. Signals would just fly up into the heavens and disappear. Everyone knew that. Or thought they did. Marconi and his men heard the signal some 25 times that day, but they made no announcements to the curious members of the press waiting in town. For three more days, they kept their windy vigil on Signal Hill. Finally, when they realized they were not likely to get any stronger signals, Marconi called for a photographer to come up and make a photographic record of the men who had made history here. On December 16, 1901, the world press headlined the scientific story of the year. Marconi had confounded the world's leading physicists. He proved that a message tapped out in Cornwall could be sent forth on an electromagnetic wave, and ride over the curving Atlantic at roughly the speed of light, curving over the sea as the earth curved.

Marconi realized that the waves might be used to send wireless messages similar to the dot-and-dash messages sent by telegraphs. He began experimenting and within a year was sending messages over distances of more than a mile (1.6 km). Widespread use of radio was assured on December 12, 1901, when assistants in England sent the first transatlantic signals to Marconi in Newfoundland, a distance of some 4800 km (3,000 miles).

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.

See Online Courses Search Inventors The Invention of Radio Radio owes its development to two other inventions, the telegraph and the telephone, all three technologies are closely related. (Read the history found on the telegraph and telephone pages to better understand the roots of radio) Few radio broadcasts travel through the air exclusively, while many are sent over telephone wires. In the 1860s, James Clerk Maxwell , a Scottish physicist, predicted the existence of radio waves, and in 1886 Heinrich Rudolph Hertz , a German physicist, demonstrated that rapid variations of electric current could be projected into space in the form of radio waves similar to those of light and heat. Guglielmo Marconi , an Italian inventor, proved the feasibility of radio communication. He sent and received his first radio signal in Italy in 1895. By 1899 he flashed the first wireless signal across the English Channel and two years later received the letter "S", telegraphed from England to Newfoundland. This was the first successful transatlantic radiotelegraph message in 1902.

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 Marchese Marconi We are going through a period where many of the key points in the formation of radio are reaching their 100th year aniversary. But is this mentioned anywhere? All we hear is the Millenium celebrations and I bet there isn't even a planned exhibition in the Greenwich dome about Marconi and the history of radio. As it quietly passes it's one hundreth aniversary we just seem to be celebrating the 2000 year aniversary of Jesus Christ and for my money Marconi did far more for the planet than Jesus even did. Controversial? You bet it is! Guglielmo Marchese Marconi (1874-1937) Guglielmo Marconi was born on the morning of 25th of April 1874 at the Palazzo Marescalchi in the Italian city of Bologna. Guglielmo being Italian for William. Marconi was the son of a well-to-do business man called Giuseppe and his second wife, Annie. Annie came from an Scotish - Irish family called the Jamesons, who were, and are famous as whisky distillers. Annie was born at Daphne Castle, Enniscorthy, Co. Wexford, Ireland, and went to study music at the Bologna Conservatory. As a young man Marconi read about the work of Heinrich Hertz in an Italian electrical journal, but they had only been of passing interest to Marconi at that time.
