"https://sb" : "http://b") + ".scorecardresearch.com/beacon.js' %3E%3C/script%3E")); 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.

Nobel Lecture Biography 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.

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.

Radio technology began as "wireless telegraphy". Radio can refer to either the electronic appliance that we listen with or the content listened to. However, it all started with the discovery of "radio waves" - electromagnetic waves that have the capacity to transmit music, speech, pictures and other data invisibly through the air. Many devices work by using electromagnetic waves including: radio, microwaves, cordless phones, remote controlled toys, television broadcasts, and more.

First to patent. First practical. Entrepreneur. Birth: April 25, 1874 in Bologna, Italy Death: July 20, 1937 in Rome, Italy Nationality: Italian Guglielmo Marchese Marconi , Italian electrical engineer and Nobel laureate, known as the inventor of the first practical radio-signaling system. He was born in Bologna and educated at the University of Bologna. As early as 1890 he became interested in wireless telegraphy, and by 1895 he had developed apparatus with which he succeeded in sending signals to a point a few kilometers away by means of a directional antenna. After patenting his system in Great Britain, he formed (1897) Marconi's Wireless Telegraph Company, Ltd., in London. In 1899 he established communication across the English Channel between England and France, and in 1901 he communicated signals across the Atlantic Ocean between Poldhu, in Cornwall, England, and St. John's, in Newfoundland, Canada. His system was soon adopted by the British and Italian navies, and by 1907 had been so much improved that transatlantic wireless telegraph service was established for public use. Marconi was awarded honors by many countries and received, jointly with the German physicist Karl Ferdinand Braun, the 1909 Nobel Prize in physics for his work in wireless telegraphy. During World War I he was in charge of the Italian wireless service and developed short-wave transmission as a means of secret communication. In the remaining years of his life he experimented with shortwaves and microwaves.

Branch of Science Engineers Nationality Italian ... Physics Prize Marconi, Guglielmo (1874-1937) Italian electrical engineer who used Heinrich Hertz's method of producing radio waves with a device called a coherer to detect them. The coherer was a container of loosely packed metal filings which conducted significant current only when radio waves fell upon it. He gradually improved his instruments, until he could receive signal over the distance of miles. After the Italian government showed no interest, he went to England and obtained the first patent in the history of radio. On December 12, 1901, he sent a radio signal across the Atlantic. As radio waves should only be capable of traveling in straight line, the success of this experiment was a bit puzzling. This led Heaviside and Kennelly to propose the existence of an electrified layer in the upper atmosphere, soon dubbed the ionosphere Experimental verification of the existence of the ionosphere however, did not come until the propagation work by Appleton and Barnett in England and pulsed radar by Breit and Truve in America. In 1909, Marconi shared the Nobel Prize in physics with Braun.

PHYSICISTS A B C ... CONTACT entire Web this site Italian physicist and Nobel Prize winner who, for several years, became involved with the possibility of radio communication with extraterrestrial intelligence. His first public comments on the subject appeared on the front page of The New York Times on January 20, 1919, under the headline "Radio to Stars, Marconi's Hope." Marconi expressed his belief that there may be many inhabited worlds, that mathematics might serve as a common language of communication (see mathematics, as a universal language ), and that unexplained signals he had detected might have been sent by intelligent beings in space. A year later the Daily Mail in London reported that Marconi had found "very queer sounds and indications, which might come from somewhere outside the Earth," including Morse code. Subsequently, The New York Times followed up the story, stimulating comments from a number of scientists and engineers around the world. Although Marconi said nothing more on the subject, the possibility of radio communication with extraterrestrials created much public excitement at the coming close opposition of Mars in 1924. By this time, most professional astronomers agreed that there was little chance of finding advanced martians. But one who had not yet given up hope of making contact with the inhabitants of the Red Planet was David P.

18. Guglielmo Marconi Lively account of Marconi s life, with a focus on the first wireless message across the Atlantic. From the First Electronic Church of America. http://www.fecha.org/marconi.htm

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.
