100 years Ago 1st January 1905, The wireless telegraphy act (1904) comes into effect clearing the letgal position rigarding the handling of commercial messages via wireless telegraphy.. May 1905 Tests started to Glace Bay, by June 2 way conversation was possible in daylight.. July 1905 Marconi takes out a patent for the directional "Bent Aerial" system.. Also in 1905 Marconi opens a new factory in London at Dalston The Marconi Company e-mail any comments to The Webmaster Metal Buttons courtesy Claire Bull But I'm afraid her graphics pages appear to have gone. A history of The Marconi Company in Chelmsford In 1898 the first wireless factory was established in Hall Street, employing around 50 people. The factory was built in what was initially a silk factory. This building still stands today and is used by the Essex and Suffolk Water Co. To get a better understanding of Chelmsford in the 1850's, I have included a map of the period. This map is interactive, and clicking on an area of interest will enlarge the section. If preferred a copy of this map may be downloaded via my download pages. Note that Hall Street is not shown on this map. This lies in the southwest corner of the map in the Hamlet of Moulsham.

43. 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/

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 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.

Wirelesss Telegraphy Spartacus USA History British History Second World War ... Email Many scientists have made contributions to the practical aspects of wireless radio broadcasting. In the 1860s the British scientist James Clerk Maxwell predicted the possibility of generating electromagnetic waves that would travel at the speed of light. Twenty years later the German physicist Heinrich Hertz demonstrated this radiation (hence the word radio). He found that when he generated sparks between two metal balls they could be found by a metal loop with a gap in it. Smaller sparks were seen jumping across this gap. Later experimenters managed to increase the distance across which Hertzian waves could be transmitted, and in 1894 a British scientist, Oliver Lodge, sent Morse-code signals over a distance of half a mile. In 1895 the Russian physicist, Aleksandr Stepanovich Popov, built a receiver to detect electromagnetism in the atmosphere and he predicted that it might be used to pick up generated signals. The next year he arranged a demonstration in the University of St Petersburg where messages were sent and received between different points. Meanwhile, electromagnetism work was being carried out independently in Italy by a young scientist

Weather Guglielmo Marconi (1874-1937) On a German stamp celebrating one hundred years of radio transmission Early in the 19th century, Michael Faraday , an English physicist, demonstrated that an electrical current could produce a magnetic field. In 1864, James Clerk Maxwell , a professor of experimental physics at Cambridge, proved mathematically that any electrical disturbance, that generates an electromagnetic field, could produce an effect at a considerable distance from the point at which it occurred and predicted that electromagnetic energy could travel outward from a source as waves moving at the speed of light. In 1888 Heinrich Hertz demonstrated that Maxwell’s prediction was true for transmission over a short distance. In 1901 the Italian physicist, Guglielmo Marconi , perfected a radio system that transmitted Morse code over the Atlantic Ocean.

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.
