Nachdem Alexanders Brüder Edward und Melville beide an Tuberkulose gestorben waren, siedelten Alexander und seine Eltern nach Kanada über, wo der Vater ein Ep Pahl Klima erhoffte und eine Lehrtätigkeit aufnahm. Alexander Graham Bell war ein britischer, später US-amerikanischer Audiologe, Erfinder und Großunternehmer.

In British scientist Willoughby Smith discovered that the element selenium , a semiconductor , varied its electrical resistance with the intensity of incident light.
Bell sought to use this property to develop the photophone, an invention he regarded as at least equal to his telephone.
He was able to demonstrate that the photophone was technologically feasible , but it did not develop into a commercially viable product.
Nevertheless, it contributed to research into the photovoltaic effect that had practical applications later in the 20th century. The origin of this effort was the shooting of U.
President James A. Garfield in July Bell decided that a promising approach was to use an induction balance, a by-product of his research on canceling out electrical interference on telephone wires.
Bell determined that a properly configured induction balance would emit a tone when a metal object was brought into proximity with it.
Surgeons adopted it, and it was credited with saving lives during the Boer War — and World War I — In September the Bell family vacationed in Nova Scotia, Canada, and immediately fell in love with the climate and landscape.
During the s Bell shifted his attention to heavier-than-air flight. Starting in , inspired by the research of American scientist Samuel Pierpont Langley , he experimented with wing shapes and propeller blade designs.
He continued his experiments even after Wilbur and Orville Wright made the first successful powered, controlled flight in In Bell founded the Aerial Experiment Association , which made significant progress in aircraft design and control and contributed to the career of pioneer aviator Glenn Hammond Curtiss.
Throughout his life, Bell sought to foster the advance of scientific knowledge. He supported the journal Science , which later became the official publication of the American Association for the Advancement of Science.
He was one of the founders of the National Geographic Society in and succeeded his father-in-law, Gardiner Hubbard, as president of the society between and In that year his son-in-law, Gilbert H.
Grosvenor , became editor in chief of the National Geographic Magazine. The extent of the [area that produced a response from the detector] having been so small, as compared with the area of the bed, it seemed reasonable to conclude that the steel mattress had produced no detrimental effect.
Meacham explained the basic principle of hydrofoils and hydroplanes. Bell considered the invention of the hydroplane as a very significant achievement.
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. Organizations such as these advocated passing laws with success in some states that established the compulsory sterilization of people deemed to be, as Bell called them, a "defective variety of the human race".
By the late s, about half the states in the U. 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.
Antonio Meucci was an accomplished inventor and deserves our recognition and respect. He patented other inventions. I respect those who have a different opinion than me.
Mine is that several inventors independently worked on a telephone device and that Alexander Graham Bell was the first to patent his and was the most successful in bringing the telephone to market.
I invite my readers to draw their own conclusions. Here is a plain English synopsis and extracts with the "whereas" language of the resolution removed.

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.
