42. Adventures In CyberSound: Marconi, Guglielmo ADVENTURES in CYBERSOUND. guglielmo marconi 1874 1937. guglielmo marconi, b. Apr. guglielmo marconi and Early Systems of Wireless Communication. by RW Simons. http://www.acmi.net.au/AIC/MARCONI_BIO.html

A D V E N T U R E S in C Y B E R S O U N D Guglielmo Marconi : 1874 - 1937 Guglielmo Marconi, b. Apr. 25, 1874, d. July 20, 1937, is known as the father of wireless. He was the son of Giuseppe Marconi of Bologna, Italy, and Annie Jameson, daughter of an Irish family. The young Marconi developed a deep interest in electrical phenomena. When he read of the experiments of Heinrich Hertz on electromagnetic waves, he became obsessed with the idea that such waves could be used for transmitting information without the need for the wire connection of the electric telegraph. In 1894, Marconi began his wireless telegraphy project by repeating some of Hertz's experiments with a number of improvements. Marconi offered his wireless communication system to the Italian government, but it was refused. In London in 1896 he first patented his system and then secured backing for it. In 1897, Marconi formed his wireless telegraph company. His four-circuit tuning, patented in 1900, led to widespread use of his system. Universal adoption of wireless telegraphy was rendered even more certain by Marconi's famous experiment in December 1901. In St. John's, Newfoundland, he received a radio-wave signal sent out from Cornwall, England.

Buy Italian Music and Book s 1895: MARCONI'S INVENTION (born 4/25/1874 d. 7/20/1937) The radio was born to the sound of a rifle shot. By September 1895, Guglielmo Marconi, a self-taught 21-year-old from Bologna , had already performed simple experiments which had convinced him that it was possible to send signals by using electro magnetic waves to connect a transmiltin, and a receiving antenna. At first, the distances were short; the one hundred meters between his house and the end of the garden; but it then became necessary to demonstrate that, by using the ether, transmission was also possible between two points separated by an obstacle. Scientists and other experts held that electromagnetic waves could only be transmitted in a straight line and then only if there was nothing in the way. Above all, they thought that the main obstacle was the curvature of the earth's surface. Marconi, (like every self-taught man) was more interested in practice than theory, and so he placed his transmitter near his house and the receiver three kilometres away, behind a hill. Overseeing it, there was the Marconi's servant, Mignani, whose only duty consisted in firing a rifle shot when the signal was received. When Mignani fired his gun, for the first time in history the three dots of the letter "S" of the Morse alphabet had traveled through space. First Marconi's radiotrasmitter used in Villa Grifone, Bologna

Marconi, Guglielmo Marconi, c. By courtesy of the Library of Congress, Washington, D.C. [Video] (b. April 25, 1874, Bologna, Italyd. July 20, 1937, Rome), 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. In 1894 Marconi began experimenting at his father's estate near Bologna, using comparatively crude apparatus: an induction coil for increasing voltages, with a spark discharger controlled by a Morse key at the sending end and a simple coherer (a device designed to detect radio waves) at the receiver. After preliminary experiments over a short distance, he first improved the coherer; then, by systematic tests, he showed that the range of signaling was increased by using a vertical aerial with a metal plate or cylinder at the top of a pole connected to a similar plate on the ground. The range of signaling was thus increased to about 2.4 km (1.5 miles), enough to convince Marconi of the potentialities of this new system of communication. During this period, he also conducted simple experiments with reflectors around the aerial to concentrate the radiated electrical energy into a beam instead of spreading it in all directions.

53. Guglielmo Marconi Short biography tells how the waves marconi was able to produce and detect laid the foundation for modern radio. http://www.marconiusa.org/marconi/index.html

Guglielmo Marconi The "Father of Radio" Radio waves were known as 'Hertzian Waves' when Marconi began experimenting in 1894. A few years earlier Heinrich Hertz had produced and detected the waves across his laboratory. Marconi's achievement was to produce and detect the waves over long distances, laying the foundations for what today we know as radio. The family home was his Italian father's villa near Bologna. His Irish mother often took Guglielmo to visit relatives in England and his formal education suffered. But in Bologna their neighbour, the distinguished physicist Professor Righi, interested the young Guglielmo in electricity generally and the work of Hertz in particular. Marconi repeated Hertz's experiments in the villa attics. Hertzian waves were produced by sparks in one circuit and detected in another circuit a few metres away. Marconi could soon detect signals over several kilometres and this led him to try and interest the Italian Ministry of Posts and Telegraphs. He was unsuccessful, but in 1896 his cousin, Henry Jameson-Davis, arranged an introduction to Nyilliam Preece, Engineer-in-Chief of the British Post Office. Encouraging demonstrations in London and on Salisbury Plain followed and in 1897 Marconi obtained a patent and established the Wireless Telegraph and Signal Company

Marconi, Guglielmo 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, thus becoming the inventor of the first practical system of wireless telegraphy. 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.
