Meine Meinung Jill <3. Ich wollte schon immer wissen wer das Telefon erfunden hatte und wie man es erfunden hatte. Mir hat dieses Thema sehr gut gefallen. Mitte des Jahrhunderts wird das Telefon gleich vierfach erfunden. Am Ende aber kassiert Alexander Graham Bell den Ruhm. Auch war dieses erste Telefon war nicht sonderlich gebrauchsfähig. meldet Alexander Graham Bell sein Telefon zum Patent an und verbesserte es immer.

Smithsonian Institution. Alexander Melville Bell. Elsie May Grosvenor Marian Fairchild. Mabel Gardiner Hubbard — English: Alexander Graham Bell was a Scottish -born inventor, teacher, scientist and philanthropist, most widely known for the invention of the telephone.
Bell invented his telephone while in Canada in , later became a U. Er gilt als der erste Mensch, der aus der Erfindung des Telefons Kapital geschlagen hat, indem er Ideen seiner Vorgänger zur Marktreife weiterentwickelte.

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. 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 — 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. Here is a plain English synopsis and extracts with the "whereas" language of the resolution removed.
You can read the full version on the Congress. He immigrated to New York from Cuba and worked on a creating an electronic communications project he called the "teletrofono" that linked different rooms and floors of his house on Staten Island.
But he exhausted his savings and couldn't commercialize his invention, " though he demonstrated his invention in and had a description of it published in New York's Italian language newspaper.
He was unable to raise sufficient funds to pay his way through the patent application process, and thus had to settle for a caveat, a one-year renewable notice of an impending patent, which was first filed on December 28, Meucci later learned that the Western Union affiliate laboratory reportedly lost his working models, and Meucci, who at this point was living on public assistance, was unable to renew the caveat after On January 13, , the Government of the United States moved to annul the patent issued to Bell on the grounds of fraud and misrepresentation, a case that the Supreme Court found viable and remanded for trial.
Meucci died in October , the Bell patent expired in January , and the case was discontinued as moot without ever reaching the underlying issue of the true inventor of the telephone entitled to the patent.
