In 1894, he built a successful storm alarm and a working radio transmitter.
By mid-1895, he had developed a radio capable of transmitting signals outdoors.
After moving to England, he found support from the British Post Office and extended his radio's range significantly.
By 1897, he was granted his first British patents and established a radio station in Italy.
Marconi's radios gained fame for facilitating communication during events like the America’s Cup yacht races.
He was awarded a British patent for improvements in wireless telegraphy, allowing multiple stations to transmit simultaneously.
Marconi believed that radio waves could follow the Earth's curvature, leading to successful long-distance transmissions.
In 1901, he received the first transatlantic signal, marking a significant milestone in radio communications.
Over the years, he continued to innovate, developing the horizontal directional antenna in 1905.
Marconi joined the Italian Fascist party in 1923 and supported Mussolini's regime.
He died in 1937, receiving a state funeral and widespread recognition for his contributions.
However, his title as the "Father of Radio" remains contested, with claims from other inventors like Tesla and Popov.
In 1943, the U.S. Supreme Court invalidated one of his patents, further fueling the debate over the invention of the radio.
Guglielmo Marchese Marconi, GCVO was an Italian electrical engineer and Nobel laureate of partially Irish descent, known for the development of a practical wireless telegraphy system commonly known as the "radio". Marconi was President of the Accademia d'Italia and a member of the Fascist Grand Council of Italy.
Birth and early years
Marconi was born near Bologna, Italy, the second son of Giuseppe Marconi, an Italian landowner, and his Irish wife [1], Annie Jameson, granddaughter of the founder of the Jameson & Sons Distillery on 25 April 1874. He was educated in Bologna, Florence and, later, in Livorno.
Wireless transmission
Although many scientists and inventors contributed to the invention of wireless telegraphy, including Christopher Smith, Reginald Fessenden, Oliver Lodge Hans Christian Ørsted, Michael Faraday, Heinrich Rudolf Hertz, Jagadis Chandra Bose, Alexander Popov, Nikola Tesla, Thomas Alva Edison, Nathan Stubblefield, and others, Marconi's system achieved widespread use, so he is often credited as the "father of radio." Marconi did use others's patents in the development of his system (such as Karl Ferdinand Braun's innovations). Braun's British patent on tuning was used by Marconi in many of Marconi's tuning patents. Marconi would later admit to Braun himself that he had "borrowed" portions of Braun's work. In the development of radio, the first person to "invent" a modern system of radio was Nikola Tesla. A variety of Tesla's radio frequency systems were demonstrated during the widely known lecture, presented to meetings of the National Electric Light Association in St. Louis, Missouri and the Franklin Institute in Philadelphia.
Transmission and radiation of radio frequency energy was a feature exhibit in the experiments by Tesla and was primarily used for the telecommunication of information.[2] Marconi supporters have stated that Marconi was not aware of the works of Nikola Tesla in the U.S. although the presentation at the Franklin Institute was reported across America and throughout Europe. It is unlikely, though, that Marconi was unaware of Tesla's presentation, "On Light and Other High Frequency Phenomena", in Philadelphia.
Marconi demonstrated the transmission and reception of Morse Code based radio signals over a distance of 2 or more kilometres (and up to 6 kilometres) on Salisbury Plain in England in 1896. Marconi was awarded a patent for Radio communications with British Patent GB12039, "Improvements in transmitting electrical impulses and signals and in apparatus there-for" on 2 July 1897 (sometimes recognised as the World's first patent in radio telecommunication). In July of 1897, Marconi formed the London based Wireless Telegraph Trading Signal Company (later renamed the Marconi Wireless Telegraph Company), which opened the World's first "wireless" factory in Hall Street, Chelmsford, England in 1898, employing around 50 people.
Marconi made a wireless transmission across water 13 May 1897 from Lavernock Point, South Wales to Flat Holm island. He made a wireless transmission across the water from Ballycastle (Northern Ireland) to Rathlin Island in 1898. He reportedly received the first trans-Atlantic radio signal on 12 December 1901 at Signal Hill in St John's, Newfoundland (now in Canada) using a 400-foot kite-supported antenna for reception.
This was surprising at the time as it was thought by some in the mainstream that a radio signal could only be transmitted in the line of sight. The transmitting station in Poldhu, Cornwall used a spark-gap transmitter to produce a signal with a frequency of approximately 500 kHz and a power of 100 times more than any radio signal previously produced (a maximum time-averaged power of 35 kilowatts, but with a peak pulse power of several tens of megawatts.[3]) The message received was three dots, the Morse code for the letter S. To reach Newfoundland the signal would have to bounce off the ionosphere twice. Dr Jack Belrose has recently contested this, however, based on theoretical work as well as an actual reenactment of the experiment; he believes that Marconi heard only random atmospheric noise and mistook it for the signal. Many other engineers agree with Jack Belrose that the 1901 bridging of the Atlantic never took place. However, equally, a significant body of intelligent scientific thought has examined the way in which this signal could have traversed the Atlantic. Of these, the most coherent (not entirely and accidental pun) is presented in a paper by Mackeand and Cross, during the Institute of Electrical Engineers (UK) Conference in 1995. While the fundamental frequency was not suitable for such a transmission, the aforementioned authors have demonstrated how high frequency harmonics of the Poldhu signal could have been received with the primitive diode detector then in use. Subsequently, ship board experiments were to comprehensively demonstrate that receiving signals over the distance claimed in 1901 was possible even when employing a far less sensitive coherer based method of detection.
Marconi then moved to longer waves (lower frequencies). However there is little doubt that by February 1902, Marconi's apparatus was reliably receiving complete messages at 2500 km (1550 miles) at night and 1100 km (700 miles) by day, and usually picked up a special test signal at 3400 km (2100 miles), the distance of Poldhu to Newfoundland. By 1903, the Marconi Company was carrying regular transatlantic news transmissions.
In 1901, Marconi built a station near Wellfleet, Massachusetts. It was first called CC (Cape Cod), then MCC (Marconi Cape Cod) and finally WCC when the US government issued "W" call letters to stations east of the Mississippi. In 1903, from this station, Marconi sent the famous message from the President of the US to the King of the United Kingdom. This message was sent directly from Welfleet to England, without being relayed via the Marconi station at Glace Bay, Nova Scotia. During WWI, all radio stations went off the air. When the war was over, Marconi had planned to move this station to Chatham, mainly because the ocean had eroded the cliff where the Welfleet station stood. Reportedly, the U.S. Government was worried about foreign ownership of radio stations.

Гульельмо Маркони, родившийся в 1874 году в Италия, был итальянским инженером-электриком, известным благодаря разработке практичной системы беспроводного телеграфа, широко известной как радио.
Несмотря на большой вклад в развитие беспроводного телеграфа, Маркони часто называют "отцом радио" из-за широкого использования его системы.
Он использовал существующие патенты, в том числе Карла Фердинанда Брауна, и признавал заимствования у других изобретателей, включая Николу Теслу.
Маркони успешно продемонстрировал передачу и прием азбуки Морзе на расстояния до 6 километров на равнине Солсбери, Англия.
Он получил свой первый патент на радиосвязь, признанный первым в мире патентом в области радиосвязи.
Маркони основал в Лондоне компанию Wireless Telegraph Trading Signal Company, которая открыла первую фабрику беспроводной связи в Челмсфорде.
Организовал беспроводную передачу данных по воде от Лавернок-Пойнт до острова Флэт-Холм.
Передавал сигналы из Балликасла, Северная Ирландия, на остров Ратлин.
Имя Маркони попало в заголовки газет, когда он, по сообщениям, принял первый трансатлантический радиосигнал на Сигнальном холме в Ньюфаундленде с помощью антенны, поддерживаемой воздушным змеем.
Эта передача была новаторской, поскольку многие считали, что радиосигналы могут передаваться только по прямой линии.
Станция Poldhu в Корнуолле использовала мощный передатчик с искровым разрядником, который подавал сигналы значительно более мощные, чем предыдущие попытки.
Полученное сообщение состояло из трех точек, обозначающих букву "S". Хотя некоторые оспаривают достоверность этого достижения, оно вызвало серьезную научную дискуссию о распространении радиоволн.
Аппарат Маркони надежно принимал сообщения на расстоянии более 2500 километров ночью и 1100 километров днем.
Его компания "Маркони" осуществляла регулярные трансатлантические передачи новостей.
Он построил станцию недалеко от Уэллфлита, штат Массачусетс, которая позже, передала знаменитое послание президента США королю Соединенного Королевства.
Его инновации заложили основу для современной радиосвязи, несмотря на продолжающиеся споры об истинном происхождении радио технологий.
