As a child Marconi, according to Robert McHenrydid not do well in school, though historian Corradi Giuliano in his biography characterizes Marconi Marconi telecommunications mexico a true genius. Radio work During his early years, Marconi had an interest in science and electricity.
One of the scientific developments during this era came from Heinrich Hertzwho, beginning indemonstrated that one could produce and detect electromagnetic radiation —now generally known as radio wavesat the time more commonly called "Hertzian waves" or "aetheric waves".
Hertz's death in brought published reviews of his earlier discoveries, and a renewed interest on the part of Marconi. He was permitted to briefly study the subject under Augusto Righia University of Bologna physicist and neighbour of Marconi who had done research on Hertz's work.
Early experimental devices Marconi Rock, Salvan, Switzerland, site of experiments Marconi began to conduct experimentsbuilding much of his own equipment in the attic of his home at the Villa Griffone in PontecchioItalywith the help of his butler Mignani.
His goal was to use radio waves to create a practical system of " wireless telegraphy "—i. This was not a new idea—numerous investigators had been exploring wireless telegraph technologies for over 50 years, but none had proven technically and commercially successful.
Marconi's system had the following components: A wire or capacity area placed at a height above the ground; A coherer receiver, which was a modification of Edouard Branly 's original device, with refinements to increase sensitivity and reliability; A telegraph key to operate the transmitter to send short and long pulses, corresponding to the dots-and-dashes of Morse code ; and A telegraph register, activated by the cohererwhich recorded the received Morse code dots and dashes onto a roll of paper tape.
Similar configurations using spark-gap transmitters plus coherer-receivers had been tried by others, but many were unable to achieve transmission ranges of more than a few hundred metres.
Marconi, just twenty years old, began his first experiments working on his own with the help of his butler Mignani. In the summer ofhe built a storm alarm made up of a battery, a coherer, and an electric bell, which went off if there was lightning.
Soon after he was able to make a bell ring on the other side of the room by pushing a telegraphic button on a bench. The next day he also showed his work to his father, who, when he was certain there were no wires, gave his son all of the money he had in his wallet so Guglielmo could buy more materials.
In the summer of Marconi moved his experimentation outdoors and continued to experiment on his father's estate in Bologna. After increasing the length of the transmitter and receiver antennas, arranging them vertically, and positioning the antenna so that it touched the ground, the range increased significantly.
Marconi wrote to the Ministry of Post and Telegraphs, then under the direction of the honorable Pietro Lacava, explaining his wireless telegraph machine and asking for funding. He never received a response to his letter which was eventually dismissed by the Minister who wrote "to the Longara" on the document, referring to the insane asylum on Via della Lungara in Rome.
Gardini wrote a letter of introduction to the Ambassador of Italy in London, Annibale Ferrero, explaining who Marconi was and about these extraordinary discoveries. In his response, Ambassador Ferrero advised them not to reveal the results until after they had obtained the copyrights.
He also encouraged him to come to England where he believed it would be easier to find the necessary funds to convert the findings from Marconi's experiment into a practical use. Finding little interest or appreciation for his work in Italy, Marconi travelled to London in early at the age of 21, accompanied by his mother, to seek support for his work; Marconi spoke fluent English in addition to Italian.
Marconi arrived at Dover and at Customs the Customs officer opened his case to find various contraptions and apparatus.
The customs officer immediately contacted the Admiralty in London. The apparatus that Marconi possessed at that time was similar to that of one in by A. Dolbearof Tufts Collegewhich used a spark coil generator and a carbon granular rectifier for reception.Learn about working at Marconi Suisse Telecommunications, S.A.R.L.
