Paperback. Zustand: New. Print on Demand. This book, published in 1926, chronicles the research of a commission established in 1920 to design and develop a revolutionary wireless communication system capable of connecting the widespread British Empire. Working closely with the Admiralty, the War Office, and eminent scientists, the commission overcame numerous technical challenges, including the design of powerful thermionic valves and the construction of massive steel masts, to create the first-of-its-kind high-power wireless station in Rugby, England. Through the detailed account of these endeavors, the author provides not only a comprehensive technical analysis of wireless technology but also a fascinating historical narrative of the birth of long-distance wireless communication. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.…

(London, Harrison and Sons, 1897). 4to. No wrappers as extracted from "Philosophical Transactions" Year 1897, Vol. 189 - A. Pp. 1-24., texfigs. First appearance of this importent paper, the first paper by Rutherford published in England, in which he describes his invention of the "Magnetic detector" before Marconi made use of it in his wireless telegraphy across the Atlantic in 1901.On his arrival at Cambridge (in 1895) his talents were quickly recognized by Professor Thomson. During his first spell at the Cavendish Laboratory, he invented the detector for electromagnetic waves, an essential feature being an ingenious magnetizing coil containing tiny bundles of magnetized iron wire. The detector made it possible to send wireless signals. …

(London, Taylor and Francis, 1902). No wrappers, as extracted from "Proceedings of the Royal Society of London.", Vol. LXX. Pp. 341-344 a. pp. 344-347. First printing of these two importent papers on wireless telegraphy, describing the inventions which made it possible to make the first wireless transmissions across the Atlantic in 1901. Maconi's apparatus was built on a magnetic detector invented by Rutherford, and was called Marconi's "Maggie". A powerfull transmitter was built at Poldu, Cornwall, England, and a large receiving antenna placed at Cape Cod, Massachusetts. Marconi succeeded to receive (on Dec. 12) three code dots, signifying the letter "S". "Already well known, Marconi, et twenty-seven, became world famous overnight."(DSB).Marconi and K.F. Brown were jointly awarded the Nobel Price in 1909 "in recognition of their services in the development of wireless telegraphy.".…

Small 8vo. 3pp. On Marconi's black-bordered Piccadilly stationery. 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.…
