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.

Z entire Web this site Marconi, Guglielmo (1874-1937) 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 Jan. 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

MARCONI, Guglielmo The brilliant man who transformed an experiment into the practical invention of radio was Guglielmo Marconi. He shared the 1909 Nobel prize in physics for the development of wireless telegraphy. Guglielmo Marconi was born on April 25, 1874, near Bologna, Italy. Even as a young boy Marconi was interested in science. He was particularly fascinated by physics, chemistry, and electricity. The boy was privately tutored and received his later scientific education at the University of Bologna. In 1894 young Marconi read an obituary of Heinrich Hertz, the discoverer of Hertzian waves, which are now known as radio waves. The young man's imagination was stirred by the account given of Hertz's work, and the idea occurred to him that Hertzian waves might be used in communication. He set to work on apparatuses for sending and receiving telegraph messages through the air and soon was able to transmit coded signals more than a mile. Marconi offered his invention to the Italian government, but it was rejected. In 1896 he went to England and took out a patent, the first ever granted for a practical system of wireless telegraphy. The next year a company was formed (later known as Marconi's Wireless Telegraph Company, Ltd.) to exploit wireless commercially. Its success made Marconi wealthy.

He detected radio waves beamed across the Atlantic in 1901, thus giving his telegraph system credibility. In 1909, Marconi shared the Nobel Prize for physics. (The Bettmann Archive) As an Italian national, Marconi played an active role in World War I and represented Italy at the Paris Peace Conference in 1919. Although he continued to perform experiments in the new field of RADIO, which evolved from wireless telegraphy, his later efforts were mainly directed to affairs of state. He received many honors, including sharing the Nobel Prize for physics in 1909. When he died in Rome, he was accorded the unique tribute of a two-minute silence by all radio stations throughout the world. Eric Eastwood Bibliography: Aitkin, Hugh G.

Guglielmo Marconi Oficinas mecânicas no quintal, laboratórios no sótão, experiências financiadas por parentes e amigos. Durante os primeiros 150 anos da Revolução Industrial - entre 1760 e as primeiras décadas deste século -, as invenções brotavam espetacularmente desse cenário romântico. Guilherme Marconi, inventor do telégrafo sem fio, foi talvez o último dos inventores individuais que marcaram essa fase da civilização. Concentrado no objetivo exclusivo da transmissão radiofônica, venceu as objeções científicas de seu tempo, superou o ceticismo míope do governo italiano e tremendas dificuldades materiais para vencer ainda jovem. Como tantos outros grandes cientistas, Marconi teve de enfrentar muito cedo a discrepância entre seus interesses espontâneos e os métodos convencionais de ensino. As lições da escola eram para ele um aborrecimento intolerável. (Casa onde nasceu) Nascido a 25 de abril de 1874, em Bolonha, desde os primeiros anos de aprendizado se entediava com o espírito acadêmico e estreito que norteava o ensino italiano da época. Era um aluno irregular, cheio de idéias próprias, que os professores puniam com más notas e repreensões. Mas a mãe, uma irlandesa, acreditava no talento do filho, estimulava seu interesse espontâneo e unilateral pela física e tomava seu partido nas divergências com os professores. Convenceu o marido a apoiar os estudos especializados do filho, que passou a tomar lições particulares. Um dos professores, Augusto Righi, de Bolonha, ele mesmo um físico de talento, viu enormes possibilidades no seu jovem aluno, e levou o velho Marconi a custear a instalação de um pequeno laboratório no sótão da casa, onde o jovem Guilherme começou a aprender o que ainda não figurava nos livros da época.

Following the success of his early experiments, Marconi was intrigued at the idea of sending messages across the Atlantic. By 1901 he had constructed a transmitting station in the southwest of England, and another in Newfoundland. On December 12 th 1901 he succeeded in making the first radio transmission across the Atlantic ocean. He was acclaimed by many famous inventors of the time including Thomas Edison. In 1909 he was awarded the Nobel Prize for Physics.

Marconi, Guglielmo Marconi made instant communication between the Old World and New World possible , and is, to a small extent, responsible for us being able to communicate as we are on the internet. He lived from 1874 to 1937. When he learned of the existence of radio waves, he started building a system that would allow the transmission of telegraph signals without wires. A year later he could transmit a signal over a distance of 2 kilometer. By 1899, he had transmitted a signal across the English Channel. In 1901, Marconi received a signal from Cornwall, England which started the dawn of transatlantic radio communications.

During 1894-95 he carried out a number of experiments in his fathers estate and achieved contact over one mile. He tried to interest the Italian government in his work but witout result. In Feb. 1896 he came to England with his mother and lost no time in making contact with various engineers and officals. His various demonstrations met with cool reception but the press loved him. With hard work and some able assistants he soon gained support and following various trials his equipment and trained operators became a naval standard. The Marconi Co. built many radio stations wordwide. His main contribution to the story of wireless communication may have been in the field of enthusiasm and drive with the ability to motivate people. top of page home page [ Version A2 20/08/98 ] HISRAD11 Page design by Webmaster
