  • The Nobel Prize in Physics 1909 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 Country Wexford, Ireland.
  • 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 1985 he began laboratory experiments at his father’s I country estate at Pontecchio where he succeeded in sending wireless signals over a distance of one and a half miles.
  • In 1896 Marconi took his apparatus to England where he was introduced to Mr. (later Sir) William Preece, Engineer-in-Chief of the Post Office, and later that year was granted the world’s first patent for a system of wireless telegraphy.
  • He demonstrated his system successfully in London, on Salisbury Plain and across the Bristol Channel , and in July, 1897 formed The Wireless Telegraph 85 Signal Company Limited (in 1900 renamed Marconi’s Wireless Telegraph Company Limited.
  • In the same year he gave a demonstration to the Italian Government at Spezia where wireless signals were sent over a distance of twelve miles.
  • In 1899 he established wireless communication between France and England across the English Channel. He erected permanent wireless stations at The Needles, Isle of Wight, at Bournemouth and later at the Haven Hotel, Poole, Dorset.
  • In 1900 he took out of his famous patent No.7777 for “tuned or syntonic telegraphy” and, on 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.
  • 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 1905 he patented his horizontal directional aerial and in 1912 a “time spark” system for generating continuous waves.
  • In 1914 he was commissioned in the Italian Army as a Lieutenant being later promoted to Captain, and in 1916 transferred to the Navy in the rank of Commander.
  • He was a member of the Italian Government mission to the United Sates in 1917 and in 1919 was appointed Italian plenipotentiary delegate to the Paris Peace Conference.
  • He was awarded the Italian Military Medal in 1919 in recognition of his war service. During his war service in Italy he returned to his investigation of short waves, which he had used in his first experiments.
  • In 1931 Marconi began research into the propagation characteristic of still shorter waves, resulting in the opening in 1932 of the world’s first microwave radiotelephone link between the
    Vatican City and the Pope’s summer residence at Castel Gandolfo.
  • Two years later at Sestri Levante he demonstrated his microwave radio beacon for ship navigation and 1935, again in Italy, gave a practical demonstration of the principles of radar, the coming of which he had first foretold in a lecture to the American Institute of Radio Engineers in New York in 1922.
  • He has been the recipient of honorary doctorates of several universities and many other international honours and awards, among them the Nobel Prize for Physics, which in 1909 he shared with Professor Karl Braun, the Albert Medal of the Royal Society of Arts, the Jin ohn Fritz Medal and the Kelvin Medal.
  • He was decorated by the Tsar of Russia with the Order of St. Anne, the King of Italy created him Commander of the Order of St. Maurice and St. Lazarus, and awarded him he Grand Cross of the Order of the Crown of Italy in 1902.
  • Marconi also received the freedom of the City of Rome (1903), and was created Chebalier of the Civil Order of Savoy in 1905.
  • In 1914 he was both created a Senatore in the Italian Senate and appointed Honrary Knight Grand Cross of the Royal Victorian Order in England. He received the hereditary title of Marchese in 1929.
  • In 1905 he married the Hon. Beatrice O’Brien, daughter of the 14th Baron Inchiquin, the marriage being annulled in 1927, in which year he married the Countess Bezzi-Scali of Rome.
  • He had one son and two daughters by his first and daughter by his second wife.
  • His recreations were hunting, cycling and motoring.  Marconi died in Rome on July 20, 1937.
