Guglielmo Marconi

Italian pioneer of long distance radio transmission, 1874-1937

"Guglielmo Marconi was an Italian inventor and electrical engineer, known for his pioneering work on long-distance radio transmission and for his development of Marconi's law and a radio telegraph system. He is often credited as the inventor of radio, and he shared the 1909 Nobel Prize in Physics with Karl Ferdinand Braun ""in recognition of their contributions to the development of wireless telegraphy"". An entrepreneur, businessman, and founder in Britain in 1897 of The Wireless Telegraph & Signal Company (which became the Marconi Company), Marconi succeeded in making a commercial success of radio by innovating and building on the work of previous experimenters and physicists."

To Australian newspaperman, Tory MP and "father" of imperial penny postage, John Henniker Heaton (1848-1914). Thanks very much for your most interesting publication on "An ideal post office." It is a great advantage to be able to get such a concise précis of your views and proposals. I think it's absurd that we have not yet got universal penny postage but you are the man to get it. I fear I shall not be in town at the time of the opening of Parliament. I therefore return you the ticket you have so kindly sent me.

When are you coming to town? My fiancée is very anxious to meet you.“ At age 20, Marconi began his experiments with electromagnetic waves, out of which he conceived the idea of wireless telegraphy. In 1900 he filed his famous Patent No. 7777 for Improvements in Apparatus for Wireless Telegraphy, allowing receiving stations to operate on different wavelengths simultaneously without interference. Marconi's fame was assured one year later when he became the first to transmit transatlantic wireless signals. In winning the Nobel Prize in 1909, he continued to conduct experiments in radio communication and eventually led his company into building short-wave broadcasting stations. Marconi and Heaton were already well acquainted. As MP, "Heaton hoped accompanied Heaton to King Edward VII's coronation in 1902. As MP, "Heaton hoped that Australian nationalism would not sever ties with Britain but his imperial federationism was practical; planning 'to stick the Empire together with a penny stamp'; he campaigned long for cheaper postal and telegraphic charges. His original scheme for imperial penny postage was derided in 1886 but in 1898 became the rule from Britain to all parts of the empire except Australia... In 1905 the first penny letter from Britain to Australia was posted and in 1911 Australia at last reciprocated. By then Heaton had espoused a new cause, penny-a-word telegrams throughout the empire." (Australian Dictionary of Biography). Our letter mentions Marconi's fiancée Beatrice O'Brien, daughter of the 14th Baron Inchiquin of Ireland. Darkly written, folded and in fine condition..

Marconi, Guglielmo

The papers of Richard Norman Vyvyan, Marconi's Chief Engineer, comprising over 30 letters by Guglielmo Marconi, letters by other correspondents including Sir Ambrose Fleming, and Vyvyan's journal recording their trial operations.

A major archive relating to the early years of transatlantic telegraphy. The engineer Richard N. Vyvyan was to a large measure responsible for both the construction and operation of the transmitting station at Poldhu in Cornwall, from where the first ever transatlantic signal was sent to Newfoundland on 12 December 1901, and in charge of the station at Cape Breton the following year when the first signal was sent the other way and a regular service established. His 1933 book "Wireless over 30 Years" remains an important source for the history of wireless. - Marconi's autograph letters, written at the time of the first transmission of telegraph signal from Canada to England, are almost all to Vyvyan, but one is to the engineer's wife, informing her that he has been "working very hard to try and find out what are the somewhat occult causes which make signals good one night and unobtainable the next, and also the reason of the great difference in distance over which signals can be sent by day compared to night. For this purpose I have had to carry out a very great number of tests between [Poldhu] and other stations on the east coast and in Scotland, and I believe I have found if not very clearly the cause of the effects noticed at least the means by which to obtain signals across the Atlantic by day as well as by night" (5 Aug. 1903). On 15 May 1904, in a "Private" letter of eight 4to pages, he provides Vyvyan with "a statement of the results obtained from the working of the Poldhu station during the last voyage of the S. S Campania, from Liverpool to New York [...] I have undertaken to carry out a series of tests to war ships stationed at different points, the receiving apparatus being taken in charge of by our assistants. I shall try various sending arrangements at Poldhu [...]". Other letters cover more domestic matters, such as Marconi's marriage ("It seems rather strange that I should have got married - doesn't it? but I am so glad that I have and we are very happy..."), their respective children (Marconi standing as godfather to Vyvyan's daughter Mildred), and their life together in a shared house at Cape Breton. - Marconi's typed letters to Vyvyan constitute a more formal series, written in Marconi's capacity as Managing Director to Vyvyan at Glace Bay, discussing personnel and equipment: "Since my return here from London a few days ago I have been carrying out some interesting work. We are at present using only about half the available power of the plant, and the results of the programme, according to latest reports, are satisfactory in the light of the arrangements which we are using at this end. I hope that, by the time this letter reaches Glace Bay, you will have received the discs which were sent in charge of the operator of the 'Empress of Ireland' last Friday" (29 Aug. 1907). - Of special interest are Vyvyan's illustrated autograph "Notes on Long Distance Wireless Telegraphy", beginning in 1900 with their work on the first transatlantic transmission ("In March of 1900 Mr Marconi after his invention of transmitting jigger decided that wireless telegraphy across the Atlantic was possible") and running on up to February 1904. A continuation volume is lacking. - The remaining correspondence archive comprises 9 letters by Sir Ambrose Fleming, co-worker with Vyvyan for Marconi and inventor of the thermionic valve ("I read of the death of Marconi in a four-days-old London Times newspaper when having tea at Vadheim in Norway [...] The obituaries which I have seen since return to England of him in the newspapers and magazines do not do justice to the cooperative work of his colleagues or of his contemporaries and I think it may be necessary to repair this omission [...] I agree with all you say about M. He had genius of a certain kind but he over-reached himself in thinking that he could appropriate the whole credit for wireless", 1901-1937), a letter by Vyvyan to his brother ("Baby has had the distinction of being the first who has ever had its birth announced by wireless telegraphy"), and a series to him by Godfrey C. Isaacs ("I would point out to you that this letter is marked 'Confidential' and therefore the handing of a copy of the letter to you must be treated as equally confidential") and by Alldin Moore ("how the dickens is [...] anyone at the Admiralty to deal with your Company except through you [...] you were & are the man one could say anything to without the fear of it being brought up in evidence later"). Several news clippings ("Television impossible [...] Official view of B.B.C.") and contemporary photographs of the transmitting station top off this fine collection that provides a vivid image of the nascent stages of a revolutionary invention.
