---- Marconi is given credit as the developer of the Wireless Telegraphy system, and holder of some of the first Wireless Telegrapy Demonstrations and Patents in sending the Morse Code, Dit Dahs, between -1896 -1901,
---- Marconi utilized an AC generator to power his tower aerial system, connected into a grounded spark induction system. The individual RF sparks emitted from the towers were made up in both short and long wave lengths, controled by the fingered Dit Dah device - See Radio Patent Information TimeLine
---- GUGLIELMO MARCONI WAS BORN in the small township of Bologna, Italy, on April 25, 1874. He died in Rome on July 20, 1937.
----We don't know Guglielmo's thinking when he was just a teenager, but we know one thing, he hated his first name Guglielmo, and his father hated the word "phony."
---- Other than that, as a young man, most of his thoughts were focused on perfecting a way to send the Morse Code and voice wirelessly through the Sky, using his own telegraphy devices, and a telephony device he picked up in Philadelphia in 1903, after a Collins' telephony demonstration.
----As the story goes, it was in 1894, when the wealthy young Italian man, just in his 20s, read an account of Hertzian waves in an electric journal his mother had just pointed out.

1. Feature (Excerpt from)  "The SMART-DAAF BOYS"™
• • Continued from above - Believe it or not, before telephony was changed to radio, the word "phony" -- bothered everyone in those early days of the wireless telephony industry. Even the name Guglielmo might have worked out for Senior Marconi too, if it could have been shortened to a trendy name.
••• Can you imagine, "Google Marconi"?
••• In the early days of wireless telephony and telegraphy, there were no packets of instant coffee and Creamora laying around, where all you had to do was add hot water.
••• As for radio, television, the Internet, WiFi, and the terms antenna, radio AC alternators, and Radio Shack, the words and entity didn't exist when Marconi and Stubblefield started their wireless operations.
••• In fact, to make telephony talk in a big way, it took Smart-Daaf Boy Stubblefield -- over eighteen years to get the government to patent the first Wireless Telephone™ system, It all started with his public demonstrations in 1892, and his 1898 basic EMW grounded electrolytic patent. As for Marconi, and his efforts to get an all-in-one patent for his Wireleess Telegraphy system, he was locked out by all nations.
••• It was Stubblefield's 1907 All-in-one articular voice / music and signal transmission patent, that separated the other Smart-Daaf Boys' wireless telegrapy, AC generators, alternators and tube element patents from Stubblefield's, especially those ancillary patents that were granted without the words, "Wireless Telegraphy," "Wireless Telephony" or "Radio" denoted on the face page of their patent. CLICK TO SEE 1907 AUTO PATENT DRAWING.
••• It took 100 years after the Stubblefield Wireless Telephone™ patent was filed, before the first group of Wireless Telephone™ frequencies were sold by the FCC for over $30-billions of dollars. (1996),. - CLICK FOR FCC FREQUENCY SALES REPORT
••• In the course of Marconi's subsequent works to make his own spark gap telegraphy system operate, he, at times, acquired the essential telegraphic and telephony ancillary licenses from others. This assured him a place in the world of physics, as a recipient of the 1909 Nobel Prize, along with Karl Braun. During World War I, Marconi was in charge of the Italian wireless service. Marconi developed shortwave secret communication transmissions during this time.
•••
Edison, A. Frederick Collins, Ambrose Fleming, NBS and Squier, were a few of the inventors that helped Marconi create the corporate success of his Marconi Wireless Telegraph Company. It was from the writings of A. Frederick Collins, where Marconi found the reasons, as to why, the "Y" was added to the words telegraph and telephone.
••• The "skY" knowledge, led him to Smart-Daaf Boy, Ambrose Fleming, the coherer glass tube, and to his first trans-atlantic Morse Code letter "S" transmission in December, 1901.
••• A few weeks later on the Potomac River, it was Smart-Daaf Boys, Stubblefield's turn. The January, 1902, ship-to-shore voice broadcast demonstration, became a first. Stubblefield had a group of Washington, D.C. dignataries listening in on both handsets and speakers. The receiver was connected to a land-line telephone connection, relaying the voice broadcast to Philadelphia listeners.
The Ambrose Fleming Oscillation Valve
••• In 1899, Ambrose Fleming became a consultant to Marconi. This was to be a crucial event that was to shape Marconi's future. Here he saw a discovery known as the Fleming Oscillation Valvet being developed in front of his eyes. It was found that the evacuated light bulb with a second electrode would allow current to flow from one electrode to the other, but only in one direction.
••• By evacuating glass tube of unwanted particles, Fleming was able to produce a stable, dependable coherer device in which Marconi introduced to his ground earth induction coils. Each had varied electrical characteristics for each transmitting and receiving antennas, thereby enabling him to tuning them to to each other.
•••This made it possible for a great number of stations to use the "air" at one time without interference. The Fleming Electron Tubel Device, the Oscillation Valve was patented in 1904, as a Telegraphy device. MORE AMBROSE STORY.
---- Marconi soon discovered that if all Hertz had to do to send a spark of electricity across a room to produce a visible spark, was ground the tuning fork and coil properly, why couldn't a coherer be used as an ancillary. Using the already developed coherer in place of his spark gap device, Marconi and his consultant, Ambrose Fleming, found that by properly grounding the coherer to his new 1900 - "four seven's" patent No. 7777, the effect would multiply the distance a thousand times over the stop gap signal, he was using to send Dit - Dahs.
----He later found out that this was because a coherer required less than one thousandth of the energy necessary to produce a visible spark.
---- Marconi, even as a Nobel Peace Prize winner, said, "he never claimed to be a scientist." He always stated his ability lay in combining certain facts discovered and developed by others. Marconi's first transmitter consisted of an elevated antenna with the spark gap located at its lower end. The end itself was solidly connected by the NBS anenna system to the earth. His receiving antenna carefully duplicated the transmitting antenna with the coherer positioned where the spark gap was. His first efforts succeeded in transmitting a signal three-fourths of a mile across his father's estate.

02 / The Smart Daaf Boys Timeline / MARCONI
• 1874 - Guglielmo Marconi was born on 25 April 1874, near Bologna, Italy, the second son of Giuseppe Marconi, an Italian landowner, and his Irish wife, Annie Jameson, granddaughter of the founder of the Jameson Whiskey distillery. He was educated in Bologna, Florence and, later, in Livorno, and was brought up as a Protestant. He briefly attended Rugby School in the United Kingdom.
• 1894 - Guglielmo Marconi, the wealthy young Italian man, just in his 20s, read an account of Hertzian waves in an electric journal his mother had pointed out.
••• The spark hit, his vacation was cut short, and he rushed back to his home-lab facilities, to test the sparkling ideas that had struck him.
• 1894 - Radio waves were known as 'Hertzian Waves' when Marconi began experimenting in 1894. A few years earlier Heinrich Hertz had produced and detected the waves across his laboratory. Marconi's achievement was to produce and detect the waves over long distances, laying the foundations for what today we know as radio
• 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 & Signal Company Limited (in 1900 re-named 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.
• 1897 - Marconi formed The Wireless Telegraph & Signal Company Limited (in 1900 re-named 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
.• 1897 - 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)
• 1897 - Marconi made a wireless transmission across water on May 13, 1897 from Lavernock Point, South Wales to Flat Holm island. 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 (122-metre) kite-supported antenna for reception.
• 1897 - U.S. Patent 0586193, Marconi "Transmitting Electrical Signals", (using Ruhmkorff coil and Morse code key) filed Dec. 7, 1896, Granted July 13, 1897. CLICK TO VIEW PATENT
• 1898 - London based Wireless Telegraph Trading Signal Company (later renamed the Marconi Wireless Telegraph Company), opened the World's first "wireless" factory in Hall Street, Chelmsford, England in 1898, employing around 50 people.
• 1898 - In March, 1898 Marconi flashed a message across the English Channel. He made a wireless transmission across the water from Ballycastle (Northern Ireland) to Rathlin Island.
• 1899 - at the invitation of the New York Herald, Marconi came to America and transmitted reports on the America Cup races from a ship out of sight of land to a shore&endash;based receiver.
• 1899 - Ambrose Fleming became a consultant to Marconi. This was to be a crucial event that was to shape Marconi's future. Here he saw a discovery known as the Fleming Oscillation Valvet being developed in front of his eyes.

• 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.
• 1901 - first trans-atlantic Morse Code letter "S" transmission in December, 1901. Marconi's antenna, held aloft by a kite, responded to the faint signal -- -di di dit - letter, "S", that was purportedly transmitted from Poldhun Cornwall, Wales. The "S" was supposedly heard by Marconi with the earphone held closely to his ear.
••• Marconi and his men heard the signal some 25 times that day, but they made no announcements to the curious members of the press waiting in town. For three more days, they kept their windy vigil on Signal Hill. Finally, when they realized they were not likely to get any stronger signals, Marconi called for a photographer to come up and make a photographic record of the men who had made history here. On December 16, 1901, the world press headlined the scientific story of the year. Marconi had confounded the world's leading physicists. He proved that a message tapped out in Cornwall could be sent forth on an electromagnetic wave, and ride over the curving Atlantic at roughly the speed of light, curving over the sea as the earth curved.
••• Scientists then didn't know why that signal curved, but any physics teacher, any encyclopedia can now tell you why. It's because of something called the ionosphere.
• 1902 - Marconi continued to use longwaves (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.
• 1902 - Marconi has been the recipient of honorary doctorates of several universities and many other international honors and awards. 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 the Grand Cross of the Order of the Crown of Italy in 1902.
• 1903 - He received the freedom of the City of Rome (1903), and was created Chevalier of the Civil Order of Savoy in 1905. Many other distinctions of this kind followed. In 1914 he was both created a Senatore in the Italian Senate and app ointed Honorary Knight Grand Cross of the Royal Victorian Order in England. He received the hereditary title of Marchese in 1929.
• 1903 - Marconi's thoughts were focused on perfecting a way to send the Morse Code and voice wirelessly through the Sky, using his own telegraphy devices, and a telephony device he picked up in Philadelphia in 1903, after a Collins' telephony demonstration.
• 1904 - US Patent 760,463, Marconi "Wireless Signaling System" Filed Sept. 10, 1903, Issued May 24, 1904. CLICK TO VIEW PATENT
• 1904 - US Patent 763,772, Marconi "Apparatus for Wireless Telegraphy" Filed Nov. 10 1900 , Issued June 28, 1904. The 1904 U.S. version of the 7777 patent,  US patent No. 763,772, was found to be invalid in a celebrated 1943 Supreme Court decision. CLICK TO VIEW PATENT
• 1905 - Marconi has been the recipient of honorary doctorates of several universities and many other international honors and awards. and was created Chevalier of the Civil Order of Savoy in 1905. Many other distinctions of this kind followed.
• 1905 - On 16 March 1905 he married Beatrice O'Brien, daughter of Edward Donough O'Brien, 14th Baron Inchiquin, Ireland. They had three daughters (one of whom lived only a few weeks), and one son. Marconi and O'Brien later divorced.
• 1907 - Marconi achieved fully reliable transatlantic communication.
• 1909 -
Nobel Prize - Marconi is recipient of the Nobel Prize in Physics along with Karl Ferdinand Braun. During World War I, Marconi was in charge of the Italian wireless service. Marconi developed shortwave secret communication transmissions during this time.
• 1914 - Marconi 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 States 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.
• 1914 - Marconi built WCC in Chatham, Massachusetts, on Cape Cod. It would become the busiest ship to shore radio station for most of the twentieth century. WCC was sold during the breakup of RCA in the 1990s to MCI, and was finally shut down in 1997. In its final years on the Cape, WCC was operated remotely over a fiber optic link right down to such details as antenna adjustments and frequency tuning from California's KPH. It ended life on Cape Cod with a two-man crew. A film documentary of this chapter of Marconi's career was produced. It was narrated by journalist Walter Cronkite and directed by filmmaker Christopher Seufert. The callsign WCC is still heard over the radio from Globe Wireless's automated radio-based email system from a new location in Maryland.
• 1914 - Marco ni was both created a Senatore in the Italian Senate and app ointed Honorary Knight Grand Cross of the Royal Victorian Order in England.
• 1917 - Marconi was a member of the Italian Government mission to the United States 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.

• 1919 - Marconi was awarded the Italian Military Medal in 1919 in recognition of his war service.
• 1920 - Marconi's Chelmsford factory was the location of the first officially publicised sound broadcasts in the UK.
• 1922 - the World's first regular wireless broadcasts for entertainment commenced from the Marconi Research Centre at Writtle near Chelmsford.
• 1922 - the BBC was established.
• 1922 - Marconi first foretold the principles of radar in a lecture to the American Institute of Radio Engineers in New York.
• 1923 - Marconi joined the Italian Fascist party. Benito Mussolini made Marconi President of the Accademia d'Italia, which also made him a member of the Fascist Grand Council. He made Fascist speeches on the radio in a number of countries.
• 1927 - On 15 June 1927, he married Maria Cristina Bezzi-Scali; Mussolini was best man. Their daughter was named Maria Elettra Elena Anna Marconi. Two years later, he was created a marchese (marquess) by King Victor Emmanuel III..
• 1929 -
Marconi received the hereditary title of Marchese in 1929.
• 1931 - Marconi began research into the propagation characteristics 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 in 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.-
• 1931 - Maxwell's ether therory dies, November, 13, 1931.
• 1934 - Marconi at Sestri Levante demonstrated his microwave radio beacon for ship navigation.
• 1935 - Marconi again in Italy, gave a practical demonstration of the principles of radar.
• 1937 -
Guglielmo Marconi died of a heart attack in Rome on July 20, 1937. As a tribute to Marconi, radio stations throughout the world observed two minutes of radio silence
• 1943 - On June 21, 1943 the Supreme Court of the United States held the broad claims of Guglielmo Marconi's patent for improvements in apparatus for wireless telegraphy to be invalid. First written for publication by the Antique Wireless Association, this monograph shows how the nation's high court arrived at its decision. It provides an answer to the continuing argument regarding the popular misconception that Marconi invented radio.
03 Editors Patent Notes: Marconi applied for his original and basic patent in 1896. Four years later he was granted a patent on a four circuit tuning system, which demonstrated his use and understanding of series tuning systems wherein the second tuned circuit refined that which was selected by the first, and so on. In March, 1898 Marconi flashed a message across the English Channel. In 1899, at the invitation of the New York Herald, Marconi came to America and transmitted reports on the America Cup races from a ship out of sight of land to a shore&endash;based receiver.
---- Marconi wanted to prove the value of wireless telegraphy, but we will go on to his most dramatic feat. His equipment spanned 2,000 miles of broad, curving ocean, a barrier which many famous scientists said could not be done: Electromagnetic waves would not travel around a curve. But on December 12, 1901, two weeks before Stubblefield's public demonstrations, Marconi's antenna, held aloft by a kite, responded to the signal -- -di di dit - letter, "S", that was purportedly transmitted from Poldhun Cornwall, Wales. The "S" was supposedly heard by Marconi with the earphone held closely to his ear.
---- The coherer, as invented by Branly and refined by Marconi, was essentially a go&endash;no&endash;go device. In the presence of a magnetic field its particles cohered and lost most of their electrical resistance so that a battery derived electric current could be directed through the device and activate a telegraphic sounder. Then the coherence would be mechanically interrupted while the system awaited a following pulse of magnetic energy.
----- While this is satisfactory for telegraphy, it would not respond to reception of sound&endash;modulated electromagnetic waves. To "detect" such waves, radio waves, if you will, a device that responded to the intensity or amplitude of the signal was required, such as the transmitter/receiver used by Stubblefield.
