    Biography

    Early years

    Marconi was born into the Italian nobility as Guglielmo Giovanni Maria Marconi[8] in Bologna on 25 April 1874,the second son of Giuseppe Marconi (an Italian aristocratic landowner from Porretta Terme) and his Irish/Scotswife Annie Jameson (daughter of Andrew Jameson of Daphne Castle in County Wexford, Ireland andgranddaughter of John Jameson, founder of whiskey distillers Jameson & Sons[9]). Between the ages of two andsix, Marconi and his elder brother Alfonso were brought up by his mother in the English town of Bedford.[10][11]After returning to Italy, at age 18 University of Bologna physicist Augusto Righi, neighbour of Marconi who haddone research on Heinrich Hertz's work, permitted Marconi to attend lectures at the university and use the lab andlibrary as well.[12] Marconi received further education in Florence at the Istituto Cavallero and, later, inLivorno.[13] Marconi did not do well in school, according to Robert McHenry,[14] though historian GiulianoCorradi characterizes him in his biography as a true genius.[15] He was baptized as a Catholic but had been broughtup as a member of the Anglican Church, being married into it (although this marriage was later annulled). Marconiwas confirmed in the Catholic faith and became a devout member of the Church before his marriage to MariaChristina in 1927.[16]

    Radio work

    During his early years, Marconi had an interest in science and electricity and in the early 1890s he began workingon the idea of "wireless telegraphy"—i.e., the transmission of telegraph messages without connecting wires as usedby the electric telegraph. This was not a new idea; numerous investigators and inventors had been exploringwireless telegraph technologies and even building systems using electric conduction, electromagnetic inductionand optical (light) signalling for over 50 years, but none had proven technically and commercially successful. Arelatively new development came from Heinrich Hertz, who demonstrated beginning in 1888 that one couldproduce and detect electromagnetic radiation—now generally known as radio waves, at the time more commonlycalled "Hertzian waves" or "aetheric waves".

    There was a great deal of interest in radio waves in the physics community, but the interest was in radio as ascientific phenomenon, not in its potential as a communication method. Physicists generally looked on radio wavesas an invisible form of light, a short range phenomenon which could only travel along a line of sight path, and thusits range was limited to the visual horizon like existing forms of visual signaling, making it unsuitable for longdistance communication.[17] Hertz's death in 1894 brought published reviews of his earlier discoveries including ademonstration on the transmission and detection of radio waves by the British physicist Oliver Lodge and an

    article about Hertz's work by Marconi's teacher, Augusto Righi. Righi's article renewed Marconi's interest indeveloping a wireless telegraphy system based on radio waves,[18] a line of inquiry that he noted other inventorsdid not seem to be pursuing.[6]

    Developing radio telegraphy

    Marconi, just twenty years old, began to conduct experiments, buildingmuch of his own equipment in the attic of his home at the Villa Griffone inPontecchio, Italy with the help of his butler Mignani. In the summer of1894, he built a storm alarm made up of a battery, a coherer (an earlydetector that changed resistance when exposed to radio waves), and anelectric bell, which went off if there was lightning. Soon after he was ableto make a bell ring on the other side of the room by pushing a telegraphicbutton on a bench.[19]

    One night in December 1894, Guglielmo woke his mother and invited herinto his secret workshop and showed her the experiment that he hadcreated. The next day, he also showed his work to his father, who gave hisson all of the money he had in his wallet when he was certain that therewere no wires, so that Guglielmo could buy more materials.

    Marconi read through the literature and picked up on the ideas of physicistswho were experimenting with radio waves, but did a great deal to developdevices, such as portable transmitters and receiver systems, that could workover long distances,[6] turning what was essentially a laboratory experimentinto a useful communication system.[20] Marconi came up with a functionalsystem with many components:[21]

    A relatively simple oscillator or sparkproducing radio transmitter;A wire or metal sheet capacity area suspended at a height above theground;A coherer receiver, which was a modification of Edouard Branly'soriginal device with refinements to increase sensitivity andreliability;A telegraph key to operate the transmitter to send short and long pulses, corresponding to the dotsanddashes of Morse code; andA telegraph register activated by the coherer which recorded the received Morse code dots and dashes onto aroll of paper tape.

    In the summer of 1895, Marconi moved his experimentation outdoors and continued to experiment on his father'sestate in Bologna. He tried different arrangements and shapes of antenna but even with improvements he was onlyable to transmit signals up to onehalf mile, a distance Oliver Lodge had predicted in 1894 as the maximumtransmission distance for radio waves.

    Transmission breakthrough

    A breakthrough came that summer when Marconi found that much greater range could be achieved after he raisedthe height of his antenna and, borrowing from a technique used in wired telegraphy, grounding his transmitter andreceiver. With these improvements the system was capable of transmitting signals up to 2 miles (3.2 km) and overhills.[22][23] The monopole antenna reduced the frequency of the waves compared to the dipole antennas used by

    Hertz, and radiated vertically polarized radio waves which could travel longer distances. By this point, heconcluded that a device could become capable of spanning greater distances, with additional funding and research,and would prove valuable both commercially and militarily. Marconi's experimental apparatus proved to be thefirst engineeringcomplete, commercially successful radio transmission system.[24][25][26]

    Marconi wrote to the Ministry of Post and Telegraphs, then under the direction of the honorable Pietro Lacava,explaining his wireless telegraph machine and asking for funding. He never received a response to his letter whichwas eventually dismissed by the Minister who wrote "to the Longara" on the document, referring to the insaneasylum on Via della Lungara in Rome.[27]

    In 1896, Marconi spoke with his family friend Carlo Gardini, Honorary Consul at the United States Consulate inBologna, about leaving Italy to go to England. Gardini wrote a letter of introduction to the Ambassador of Italy inLondon, Annibale Ferrero, explaining who Marconi was and about these extraordinary discoveries. In hisresponse, Ambassador Ferrero advised them not to reveal the results until after they had obtained the copyrights.He also encouraged him to come to England where he believed it would be easier to find the necessary funds toconvert the findings from Marconi's experiment into a practical use. Finding little interest or appreciation for hiswork in Italy, Marconi travelled to London in early 1896 at the age of 21, accompanied by his mother, to seeksupport for his work. (He spoke fluent English in addition to Italian.) Marconi arrived at Dover and the Customsofficer opened his case to find various contraptions and apparatus. The customs officer immediately contacted theAdmiralty in London. While there, Marconi gained the interest and support of William Preece, the Chief ElectricalEngineer of the British Post Office.

    The British become interested

    Marconi made his first demonstration of his system for theBritish government in July 1896.[28] A further series ofdemonstrations for the British followed—by March 1897,Marconi had transmitted Morse code signals over a distance ofabout 6 kilometres (3.7 mi) across Salisbury Plain. On 13 May1897, Marconi sent the world's first ever wirelesscommunication over open sea. The experiment, based in Wales,witnessed a message transversed over the Bristol Channel fromFlat Holm Island to Lavernock Point in Penarth, a distance of 6kilometres (3.7 mi). The message read "Are you ready".[29] Thetransmitting equipment was almost immediately relocated toBrean Down Fort on the Somerset coast, stretching the range to16 kilometres (9.9 mi).

    Impressed by these and other demonstrations, Preece introducedMarconi's ongoing work to the general public at two importantLondon lectures: "Telegraphy without Wires", at the ToynbeeHall on 11 December 1896; and "Signaling through Spacewithout Wires", given to the Royal Institution on 4 June 1897.

    Numerous additional demonstrations followed, and Marconi began to receive international attention. In July 1897,he carried out a series of tests at La Spezia, in his home country, for the Italian government. A test for Lloydsbetween Ballycastle and Rathlin Island, Ireland, was conducted on 6 July 1898. The English channel was crossedon 27 March 1899, from Wimereux, France to South Foreland Lighthouse, England, and in the autumn of 1899,the first demonstrations in the United States took place, with the reporting of the America's Cup international yachtraces at New York.

    Marconi sailed to the United States at the invitation of the New York Heraldnewspaper to cover the America's Cup races off Sandy Hook, NJ. Thetransmission was done aboard the SS Ponce, a passenger ship of the Porto RicoLine.[30] Marconi left for England on 8 November 1899 on the American Line'sSS Saint Paul, and he and his assistants installed wireless equipment aboardduring the voyage. On 15 November Saint Paul became the first ocean liner toreport her imminent return to Great Britain by wireless when Marconi's RoyalNeedles Hotel radio station contacted her sixtysix nautical miles off the Englishcoast.

    Transatlantic transmissions

    At the turn of the 20th century, Marconi began investigating the means to signalcompletely across the Atlantic in order to compete with the transatlantic telegraphcables. Marconi established a wireless transmitting station at Marconi House,Rosslare Strand, Co. Wexford in 1901 to act as a link between Poldhu inCornwall, England and Clifden in Co. Galway, Ireland. He soon made theannouncement that the message was received at Signal Hill in St John's,Newfoundland (now part of Canada) on 12 December 1901, using a 500foot

    (150 m) kitesupportedantenna for reception—signals transmitted by thecompany's new highpowerstation at Poldhu, Cornwall.The distance between thetwo points was about 2,200miles (3,500 km). It washeralded as a great scientificadvance, yet there also was—and continues to be—considerable skepticismabout this claim. The exactwavelength used is notknown, but it is fairlyreliably determined to havebeen in the neighborhood of350 meters (frequency≈850 kHz). The tests took place at a time of day during which the entiretransatlantic path was in daylight. We now know (although Marconi didnot know then) that this was the worst possible choice. At this mediumwavelength, long distance transmission in the daytime is not possiblebecause of heavy absorption of the skywave in the ionosphere. It was nota blind test; Marconi knew in advance to listen for a repetitive signal of three clicks, signifying the Morse codeletter S. The clicks were reported to have been heard faintly and sporadically. There was no independentconfirmation of the reported reception, and the transmissions were difficult to distinguish from atmospheric noise.(A detailed technical review of Marconi's early transatlantic work appears in John S. Belrose's work of 1995.) ThePoldhu transmitter was a twostage circuit.[33][34]

    Marconi caricatured by Spy forVanity Fair, 1905

    Feeling challenged by skeptics,Marconi prepared a better organizedand documented test. In February1902, the SS Philadelphia sailedwest from Great Britain withMarconi aboard, carefully recordingsignals sent daily from the Poldhustation. The test results producedcoherertape reception up to 1,550miles (2,490 km), and audioreception up to 2,100 miles(3,400 km). The maximumdistances were achieved at night,and these tests were the first toshow that radio signals for mediumwave and longwave transmissions

    travel much farther at night than in the day. During the daytime, signals hadonly been received up to about 700 miles (1,100 km), less than half of thedistance claimed earlier at Newfoundland, where the transmissions had alsotaken place during the day. Because of this, Marconi had not fullyconfirmed the Newfoundland claims, although he did prove that radiosignals could be sent for hundreds of kilometres, despite some scientists'belief that they were essentially limited to lineofsight distances.

    On 17 December 1902, a transmission from the Marconi station in GlaceBay, Nova Scotia, Canada became the world's first radio message to crossthe Atlantic from North America. In 1901, Marconi built a station nearSouth Wellfleet, Massachusetts that sent a message of greetings on 18January 1903 from United States President Theodore Roosevelt to KingEdward VII of the United Kingdom. However, consistent transatlanticsignalling was difficult to establish.

    Marconi began to build highpowered stations on both sides of the Atlanticto communicate with ships at sea, in competition with other inventors. In1904, a commercial service was established to transmit nightly newssummaries to subscribing ships, which could incorporate them into theironboard newspapers. A regular transatlantic radiotelegraph service wasfinally begun on 17 October 1907[35][36] between Clifden Ireland and Glace Bay, but even after this the companystruggled for many years to provide reliable communication to others.

    Titanic

    The role played by Marconi Co. wireless in maritime rescues raised public awareness of the value of radio andbrought fame to Marconi, particularly the sinkings of the RMS Titanic on 15 April 1912 and the RMS Lusitania on7 May 1915.

    RMS Titanic radio operators Jack Phillips and Harold Bride were not employed by the White Star Line but by theMarconi International Marine Communication Company. After the sinking of the ocean liner on 15 April 1912,survivors were rescued by the RMS Carpathia of the Cunard Line.[37] Also employed by the Marconi Companywas David Sarnoff, who later headed RCA. Wireless communications were reportedly maintained for 72 hours

    “ Have I done theworld good, or haveI added amenace?[42] ”

    Marconi with his wife c. 1910

    between Carpathia and Sarnoff,[38] but Sarnoff's involvement has been questioned by some modern historians.When Carpathia docked in New York, Marconi went aboard with a reporter from The New York Times to talk withBride, the surviving operator.[37]

    On 18 June 1912, Marconi gave evidence to the Court of Inquiry into the loss of Titanic regarding the marinetelegraphy's functions and the procedures for emergencies at sea.[39] Britain's postmastergeneral summed up,referring to the Titanic disaster: "Those who have been saved, have been saved through one man, Mr.Marconi...and his marvelous invention."[40] Marconi was offered free passage on Titanic before she sank, but hadtaken Lusitania three days earlier. As his daughter Degna later explained, he had paperwork to do and preferred thepublic stenographer aboard that vessel.[41]

    Continuing work

    Over the years, the Marconi companies gained a reputation for beingtechnically conservative, in particular by continuing to use inefficientsparktransmitter technology which could only be used forradiotelegraph operations, long after it was apparent that the future ofradio communication lay with continuouswave transmissions whichwere more efficient and could be used for audio transmissions.Somewhat belatedly, the company did begin significant work with

    continuouswave equipment beginning in 1915, after the introduction of the oscillating vacuum tube (valve). TheNew Street Works factory in Chelmsford was the location for the first entertainment radio broadcasts in the UnitedKingdom in 1920, employing a vacuum tube transmitter and featuring Dame Nellie Melba. In 1922, regularentertainment broadcasts commenced from the Marconi Research Centre at Great Baddow, forming the prelude tothe BBC, and he spoke of the close association of aviation and wireless telephony in that same year at a privategathering with Florence Tyzack Parbury, and even spoke of interplanetary wireless communication.

    Later years

    In 1914, Marconi was made a Senator in the Italian Senate and appointedHonorary Knight Grand Cross of the Royal Victorian Order in the UK.During World War I, Italy joined the Allied side of the conflict, andMarconi was placed in charge of the Italian military's radio service. Heattained the rank of lieutenant in the Italian Army and of commander in theItalian Navy. In 1929, he was made a marquess by King Victor EmmanuelIII.

    Marconi joined the Italian Fascist party in 1923. In 1930, Italian dictatorBenito Mussolini appointed him President of the Royal Academy of Italy,which made Marconi a member of the Fascist Grand Council.

    Marconi died in Rome on 20 July 1937 at age 63, following a series ofheart attacks, and Italy held a state funeral for him. As a tribute, shops onthe street where he lived were "Closed for national mourning".[43] Inaddition, at 6 pm the next day, the time designated for the funeral, all BBCtransmitters and wireless Post Office transmitters in the British Islesobserved two minutes of silence in his honor. The British Post Office also

    American electrical engineer AlfredNorton Goldsmith and Marconi on 26June 1922.

    sent a message requesting that all broadcasting ships honor Marconi with two minutes of broadcasting silence aswell.[43] His remains are housed in the Villa Griffone at Sasso Marconi, EmiliaRomagna, which assumed thatname in his honour in 1938.[44][45]

    In 1943, the Supreme Court of the United States handed down a decision on Marconi's radio patents restoringsome of the prior patents of Oliver Lodge, John Stone Stone, and Nikola Tesla.[46][47] The decision was not aboutMarconi's original radio patents[48] and the court declared that their decision had no bearing on Marconi's claim asthe first to achieve radio transmission, just that since Marconi's claim to certain patents were questionable, hecould not claim infringement on those same patents.[49] (There are claims the high court was trying to nullify aWorld War I claim against the United States government by the Marconi Company via simply restoring the nonMarconi prior patent.)[46]

    Personal life

    Marconi had a brother, Alfonso, and a stepbrother, Luigi.

    On 16 March 1905, Marconi married the Hon. Beatrice O'Brien (1882–1976), a daughter of Edward O'Brien, 14th Baron Inchiquin, having met herin Poole in 1904.[50] They had three daughters, Degna (1908–1998), Gioia(1916–1996), and Lucia (born and died 1906), and a son, Giulio, 2ndMarchese Marconi (1910–1971).

    In 1913, the Marconis returned to Italy and became part of Rome society.Beatrice served as a ladyinwaiting to Queen Elena. The Marconisdivorced in 1924, and, at Marconi's request, the marriage was annulled on27 April 1927, so he could remarry.[51] Beatrice Marconi married hersecond husband, Liborio Marignoli, Marchese di Montecorona, on 3 March1924 and had a daughter, Flaminia.[52]

    On 12 June 1927 (religious 15 June), Marconi married Maria Cristina BezziScali (1900–1994), only daughter ofFrancesco, Count BezziScali. They had one daughter, Maria Elettra Elena Anna (born 1930), who married PrinceCarlo Giovannelli (born 1942) in 1966; they later divorced. For unexplained reasons, Marconi left his entirefortune to his second wife and their only child, and nothing to the children of his first marriage.[53]

    Later in life, Marconi was an active Italian Fascist[54] and an apologist for their ideology and actions such as theattack by Italian forces in Ethiopia.

    Marconi wanted to personally introduce in 1931 the first radio broadcast of a Pope, Pius XI, and did announce atthe microphone: "With the help of God, who places so many mysterious forces of nature at man's disposal, I havebeen able to prepare this instrument which will give to the faithful of the entire world the joy of listening to thevoice of the Holy Father".[55]

    Legacy and honours

    Honours and awards

    In 1909, Marconi shared the Nobel Prize in Physics with Karl Braun for his contributions to radiocommunications.[3]

    The 'Marconi's Wireless Telegraph Company of Canada' (now CMC Electronics, of Montreal, Canada, wascreated in 1903 by Guglielmo Marconi.[64] In 1925 the company was renamed to the 'Canadian MarconiCompany', which was acquired by English Electric in 1953.[64] The company name changed again to CMCElectronics Inc. (French: CMC Électronique) in 2001.The Marconi National Historic Sites of Canada was created by Parks Canada as a tribute to Marconi's visionin the development of radio telecommunications. The first official wireless message was sent from thislocation by the Atlantic Ocean to England in 1902. The museum site is located in Glace Bay, Nova Scotia, atTable Head on Timmerman Street.

    As of 2016 the Canadian Marconi Company and CMC Electronics no longer exist. Most bought up by Esterline inOttawa. The Marine Service Group was acquired by MacKay Marine but many of the employees left the group attransition.
