Guglielmo Marconi

Gugliemo Marconi – 1896

 

The main achievements of  his life and of the scientific and experimental activities of Guglielmo Marconi; the man who ushered in the modern Wireless universe in which we all live.

Guglielmo Marconi is comparable to the mysterious and vital centre of an immense galaxy from which infinite systems of bodies in continuous motion radiate and live together.

Guglielmo Marconi represents the uninterrupted progression of human research in its journey from the past to the future of modern civilization.

The Marconi Magic Box Project, was created for the centenary of the Nobel Prize for Physics awarded to the scientist, from Bologna (Stockholm, 10 December 1909).

A brief summary of  Guglielmo Marconi’s life and work, appears below.

Guglielmo Marconi (1874, Bologna; 1937, Roma)

Biographical outline, notes on his scientific and technical activities

1874, April 25

 Guglielmo Marconi was born in Bologna; his father was Giuseppe Marconi and his mother, Annie Jameson, was a young Irish Protestant. His mother grew him as a Protestant Christian, teaching him the English language. In a second phase of his life, Guglielmo Marconi was converted to Catholicism.

 1880/1894

Guglielmo Marconi did not accomplished regular studies and did not attend the university. He received his education privately at Bologna, Florence and Livorno. The privileged place for his early experiments remains the famous “bug room” at the family estate in today Sasso Marconi. Among his “guardians”, Vincenzo Rosa and Augusto Righi are particularly reported. Especially, Augusto Righi – a scientist and university professor – was publicly thanked and praised by Marconi for his contribution to his education and scientific activity, introducing him almost as “mentor”.

 

Righi and his laboratory

1894

 Marconi built his first laboratory to perform experiments on the propagation of electric waves. His family, contrary to some rumours – complained by the very Marconi – endorsed and actively and economically supported the efforts of the young scientist.
 

1895, September

The historical experiment “of Celestini” (from the name of the hill) was made; Guglielmo Marconi sent a radio signal at a distance of about 1700 meters; the brother and the bailiff, listening with the receiver, signalled the acknowledge receipt of the signal with a shot.
 
1896
 
Guglielmo Marconi moved to England, helped by his knowledge of the language but also spurred – most likely – by his enterpreurial spirit: Marconi realized that England, at the turn of the nineteenth century, was the financial and economic capital of the Planet.
 

1897, July 2

 Guglielmo Marconi received his first patent for the system of wireless telegraphy –British Patent No. 12. 039 Improvements in Transmitting Electrical Impulses and Signals, and in Apparatus therefore, applied on June 2, 1896 – opened in fact, the Wireless Universe and its career as an entrepreneur of Communications.

1897

In this important year, Gugliemo Marconi also founded the company “The Wireless Telegraph & Signal Company Limited”, later renamed “Marconi’s Telegraph Company Limited” (1900), in Chelmsford (Essex, England) and made demonstrative transmissions for the Italian government in Rome and La Spezia, coming to transmit signals to a distance of about 30 km.

1898, July

 Guglielmo Marconi followed the Sailing Ragattas of Dublin on board a ship and sent the news in real time to the Dublin’s Daily Express, which managed to publish the results before the boats’ return.

 Patent 7777 – Patent and Transmitter

1901, December 12

 After successfully transmitted signals from the Island of Wight to the tip of Cornwall (approximately 300 km), Gugliemo Marconi made a transatlantic link of nearly 3400 km, between Poldhu (Cornwall, UK) and St. John’s Newfoundland (Canada), showing empirically that the earth curvature does not affect radio transmissions.

1902

Marconi performed experiments with the detector equipment aboard the armoured cruiser Carlo Alberto, placed at his disposal by the Italian government; the same year he patented the “magnetic detector”, a step towards the “fine tuning” radio.

1902

Conducting experiments aboard the U.S. liner Philadelphia, Guglielmo Marconi first demonstrated the “daylight effect” on radio, until then only theorized by the scientific world, thus contributing to research in different fields.

1903, January 18

 Marconi opened the station of Cape Cod, near Boston, with a radio telegram of President Thodore Roosevelt to S.M. King Edward VII of England.

1915-1918

Guglielmo Marconi offered its contribution to the war effort by assisting the installation of Marconi radio equipment on board ships and – for the first time – planes. Following several incidents during the war in the use of long-wave radio systems, Marconi began the construction of the first short-wave devices in Genoa: This opened a vast horizon in the development of Radio. Here came the creation of the new-wave beam that could solve the problem of multiple and current services at very great distances.

1923, June/July

Guglielmo Marconi took a long cruise in the Atlantic Ocean on board the Elettra, carrying out major trials of the short-wave beam system; Marconi went to the island of Cape Verde, remaining in constant contact with the experimental station Poldhu. Marconi announced that only by using short-wave can be rationally and economically solved the problem of radio communications over long distances. From this memorable cruise came a new trend for the radio technology: the expensive long-wave transmitters were left to be replaced by those short-wave, that were cheaper.
