After attending school in Scotland and London, the year-old immigrated to Canada with his parents in Italian inventor and engineer Guglielmo Marconi developed, demonstrated and marketed the first successful long-distance wireless telegraph and in broadcast the first transatlantic radio signal.
On September 1, , a Boston woman named Emma Nutt made history—and all she had to do was pick up the phone. Her soothing voice helped usher in a new era of telecommunications and In his 84 years, Thomas Edison acquired a record number of 1, patents singly or jointly and was the driving force behind such innovations as the phonograph, the incandescent light bulb and one of the earliest motion picture cameras.
He was an impassioned champion of a strong federal government, and played a key role in defending Serbian-American engineer and physicist Nikola Tesla made dozens of breakthroughs in the production, transmission and application of electric power.
He invented the first alternating current AC motor and developed AC generation and transmission technology. In , Connecticut-born gun manufacturer Samuel Colt received a U.
Colt founded a company to manufacture his revolving-cylinder pistol; however, sales were slow and the By turns charismatic and ruthless, brilliant and power hungry, diplomatic and The internet got its start in the United States more than 50 years ago as a government weapon in the Cold War.
For years, scientists and Live TV. This Day In History. History at Home. Telephone In , Bell started working on the harmonic telegraph — a device that allowed multiple messages to be transmitted over a wire at the same time.
While the Bell Company faced over court challenges, in the end, none were successful. Inventions and Accomplishments In addition to the telephone, Bell worked on hundreds of projects throughout his career and received patents in various fields.

Startled by the emperor's enthusiastic response to Bell's telephone demonstration—during which the emperor exclaimed "My God! It talks! Bell, who was then a full-time teacher, had not planned to exhibit at the fair because of his heavy teaching schedule and preparation for his student's examinations.
When Bell started arguing, Mabel turned her sight away from him and became literally deaf to his protests. In Gardiner Hubbard founded the International Bell Telephone Company in order to promote sales of its telephone equipment throughout Europe.
During his tour of the continent, the Belgian government offered him the greatest financial incentives to establish his European subsidiary's headquarters in their country.
BTMC eventually came under complete ownership by Western Electric, and also established other divisions as national companies across Continental Europe and Russia.
Due to that reason and others, and also due to the U. In only a few years, Western Union's president would acknowledge that it was a serious business error, one that nearly led to his company later almost being swallowed up by the newly emerging telecommunications giant into which Bell Telephone would shortly evolve.
Western Union was saved from demise only by the U. Government's anti-monopoly interventions. The project was the first of its kind to create a nationwide long-distance network with a commercially viable cost-structure.
Starting from New York City, its long-distance telephone network reached Chicago, Illinois, in ,  with its multitudes of local exchanges continuing to stretch further and further yearly, eventually creating a continent-wide telephone system.
John Elbridge Hudson joined Bell Telephone as counsel in and served as president from to In , there was a large strike across the US against the company's long hours and low pay by its workers.
The memorial was planned to be completed by [ when? Allward designed the monument to symbolize the telephone's ability to overcome distances.
At each end of the memorial there are two female figures mounted on granite pedestals representing Humanity , one sending and the other receiving a message.
The Bell Telephone Memorial 's grandeur has been described as the finest example of Allward's early work, propelling the sculptor to fame.
The memorial itself has been used as a central fixture for many civic events and remains an important part of Brantford's history, helping the city of Brantford to style itself as 'The Telephone City'.
The Bell Memorial Association also purchased the Bell family's former farmhouse, Melville House, and its orchard at Tutela Heights, opening it as a museum to the family and to the invention of the telephone.
In , it was declared a historic landmark, and is now known as the Bell Homestead National Historic Site. From Wikipedia, the free encyclopedia.
For the Canadian telecommunications company, see Bell Canada. Based on information gained from that article, he began to sketch concepts of what is now called a hydrofoil boat.
Bell and assistant Frederick W. Baldwin studied the work of the Italian inventor Enrico Forlanini and began testing models. This led him and Bell to the development of practical hydrofoil watercraft.
During his world tour of —11, Bell and Baldwin met with Forlanini in France. They had rides in the Forlanini hydrofoil boat over Lake Maggiore.
Baldwin described it as being as smooth as flying. On returning to Baddeck, a number of initial concepts were built as experimental models, including the Dhonnas Beag Scottish Gaelic for little devil , the first self-propelled Bell-Baldwin hydrofoil.
Pinaud's experience in boat-building enabled him to make useful design changes to the HD Bell's report to the U. Navy permitted him to obtain two horsepower kilowatts engines in July On September 9, , the HD-4 set a world marine speed record of In , Bell had begun experiments to develop motor-powered heavier-than-air aircraft.
The AEA was first formed as Bell shared the vision to fly with his wife, who advised him to seek "young" help as Bell was at the age of In , Bell experimented with tetrahedral box kites and wings constructed of multiple compound tetrahedral kites covered in maroon silk.
Bell was a supporter of aerospace engineering research through the Aerial Experiment Association AEA , officially formed at Baddeck, Nova Scotia, in October at the suggestion of his wife Mabel and with her financial support after the sale of some of her real estate.
Curtiss , a motorcycle manufacturer at the time and who held the title "world's fastest man", having ridden his self-constructed motor bicycle around in the shortest time, and who was later awarded the Scientific American Trophy for the first official one-kilometre flight in the Western hemisphere , and who later became a world-renowned airplane manufacturer; Lieutenant Thomas Selfridge , an official observer from the U.
Federal government and one of the few people in the army who believed that aviation was the future; Frederick W. The AEA's work progressed to heavier-than-air machines, applying their knowledge of kites to gliders.
Moving to Hammondsport, the group then designed and built the Red Wing , framed in bamboo and covered in red silk and powered by a small air-cooled engine.
One of the AEA's inventions, a practical wingtip form of the aileron , was to become a standard component on all aircraft.
Bell allowed it to continue with experiments. Selfridge had also become the first person killed in a powered heavier-than-air flight in a crash of the Wright Flyer at Fort Myer , Virginia , on September 17, Their final aircraft design, the Silver Dart , embodied all of the advancements found in the earlier machines.
McCurdy from the frozen ice of Bras d'Or made the first aircraft flight in Canada. Bell was connected with the eugenics movement in the United States.
In his lecture Memoir upon the formation of a deaf variety of the human race presented to the National Academy of Sciences on November 13, the year of his election as a Member of the National Academy of Sciences , he noted that congenitally deaf parents were more likely to produce deaf children and tentatively suggested that couples where both parties were deaf should not marry.
The committee unequivocally extended the principle to humans. Honors and tributes flowed to Bell in increasing numbers as his invention became ubiquitous and his personal fame grew.
Bell received numerous honorary degrees from colleges and universities to the point that the requests almost became burdensome. These included statuary monuments to both him and the new form of communication his telephone created, including the Bell Telephone Memorial erected in his honor in Alexander Graham Bell Gardens in Brantford , Ontario, in A number of historic sites and other marks commemorate Bell in North America and Europe, including the first telephone companies in the United States and Canada.
Among the major sites are:. These included the prestigious 'Volta Laboratory Association' , also known as the Volta Laboratory and as the 'Alexander Graham Bell Laboratory', and which eventually led to the Volta Bureau as a center for studies on deafness which is still in operation in Georgetown, Washington, D.
The Volta Laboratory became an experimental facility devoted to scientific discovery, and the very next year it improved Edison's phonograph by substituting wax for tinfoil as the recording medium and incising the recording rather than indenting it, key upgrades that Edison himself later adopted.
In partnership with Gardiner Greene Hubbard , Bell helped establish the publication Science during the early s. In , Bell was elected as the second president of the National Geographic Society , serving until , and was primarily responsible for the extensive use of illustrations, including photography, in the magazine.
He was one of the founders of the American Institute of Electrical Engineers in and served as its president from to The First Day of Issue ceremony was held on October 28 in Boston, Massachusetts, the city where Bell spent considerable time on research and working with the deaf.
The Bell stamp became very popular and sold out in little time. The stamp became, and remains to this day, the most valuable one of the series.
The illustrations on the reverse of the note include Bell's face in profile, his signature, and objects from Bell's life and career: users of the telephone over the ages; an audio wave signal ; a diagram of a telephone receiver; geometric shapes from engineering structures; representations of sign language and the phonetic alphabet; the geese which helped him to understand flight; and the sheep which he studied to understand genetics.
That first flight was made by an airplane designed under Dr. Bell's tutelage, named the Silver Dart. In , Bell was also named as one of the 10 greatest Scottish scientists in history after having been listed in the National Library of Scotland 's 'Scottish Science Hall of Fame'.
Alexander Graham Bell, who could not complete the university program of his youth, received at least a dozen honorary degrees from academic institutions, including eight honorary LL.
Bell died of complications arising from diabetes on August 2, , at his private estate in Cape Breton, Nova Scotia, at age Bell, saying: .
My colleagues in the Government join with me in expressing to you our sense of the world's loss in the death of your distinguished husband.
It will ever be a source of pride to our country that the great invention, with which his name is immortally associated, is a part of its history. On the behalf of the citizens of Canada, may I extend to you an expression of our combined gratitude and sympathy.
Bell's coffin was constructed of Beinn Bhreagh pine by his laboratory staff, lined with the same red silk fabric used in his tetrahedral kite experiments.
To help celebrate his life, his wife asked guests not to wear black the traditional funeral color while attending his service, during which soloist Jean MacDonald sang a verse of Robert Louis Stevenson 's "Requiem": .
Upon the conclusion of Bell's funeral, "every phone on the continent of North America was silenced in honor of the man who had given to mankind the means for direct communication at a distance".
Alexander Graham Bell was buried atop Beinn Bhreagh mountain, on his estate where he had resided increasingly for the last 35 years of his life, overlooking Bras d'Or Lake.

Quote from Bell speaking to his wife: "you are a citizen because you can't help it — you were born one, but I chose to be one. On October 24, , in Brantford, Ontario, the Governor General spoke at the unveiling of the Bell Telephone Memorial to an audience numbering in the thousands, saying: "Dr.
Bell is to be congratulated upon being able to receive the recognition of his fellow citizens and fellow countrymen".
Bell's dislike of the telephone. Of course, he never had one in his study. That was where he went when he wanted to be alone with his thoughts and his work.
The telephone, of course, means intrusion by the outside world. And the little difficulties and delays often attending the establishment of conversation But all really important business over the telephone he transacted himself.
There are few private houses more completely equipped with telephones than ours Bell was more particular about than our telephone service We never could have come here [to Beinn Bhreagh] in the first place or continued here, but for the telephone which kept us in close touch with doctors and neighbors and the regular telegraph office Bell did like to say in fun, "Why did I ever invent the Telephone," but no one had a higher appreciation of its indispensableness or used it more freely when need was—either personally or by deputy —and he was really tremendously proud of it and all it was accomplishing.
It received its historical designation from the Government of Canada on June 1, Mabel's exact age when she became deaf would later play a part in the debate on the effectiveness of manual versus oral education for deaf children , as children who are older at the onset of deafness retain greater vocalization skills and are thus more successful in oral education programs.
Some of the debate centred on whether Mabel had to relearn oral speech from scratch, or whether she never lost it. It was invented in Brantford at Tutela Heights in the summer of Others transmitted a sound or a click or a buzz but our boys [Bell and Watson] were the first to transmit speech one could understand.
Bell was so ecstatic that he wanted to jointly name his new invention and his new daughter Photophone Greek: " light—sound " ,   Bell wrote: "Only think!
Mabel's baby screamed inarticulately but mine spoke with distinct enunciation from the first. Bell quickly disassembled it and effected a repair, to the owner's amazement.
When asked how he was able to do so Bell only needed to introduce himself. Bell also chose maroon-colored silk as it would show up clearly against the light-colored sky in his photographic studies.
