Vor Jahren gelang Graham Bell eine bahnbrechende Erfindung: Er entdeckte, wie man Schallwellen in elektrische Schwingungen. Ein Schauspieler in der Rolle von Alexander Graham Bell spricht in ein Telefon. 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.
Erfindung des TelefonsEin Schauspieler in der Rolle von Alexander Graham Bell spricht in ein Telefon. Mitte des Jahrhunderts wird das Telefon gleich vierfach erfunden. Am Ende aber kassiert Alexander Graham Bell den Ruhm. Dieses Patent schloss somit auch die bereits zuvor gemachte Erfindung des Deutschen Philipp Reis mit ein, nämlich dessen Telefon. Bell gründete die Firma.

Alexander Graham Bell, (born March 3, , Edinburgh, Scotland—died August 2, , Beinn Bhreagh, Cape Breton Island, Nova Scotia, Canada), Scottish-born American inventor, scientist, and teacher of the deaf whose foremost accomplishments were the invention of the telephone () and the refinement of the phonograph (). Inventions. Bell's genius is seen in part by the eighteen patents granted in his name alone and the twelve that he shared with others. These included fifteen for the telephone and telegraph, four for the photophone, one for the phonograph, five for aeronautics, four for hydrofoils, and two for a selenium cell.

Alexander Graham Bell went down in history as the inventor of the telephone. He was bor.
In , Bell was awarded the French Volta Prize, and with the money, he founded a facility devoted to scientific discovery, the Volta Laboratory in Washington, D.
Bell invented numerous techniques to help teach speech to the deaf and even worked with well-known author and activist Helen Keller. He also helped launch Science magazine , and from to served as president of the National Geographic Society.
In , Bell was given the controversial title of honorary president at the Second International Congress of Eugenics. Later in his life, Bell focused on aviation and hydrofoil inventions.
Some famous quotes attributed to Bell include:. Bell died on August 2, , at the age of 75 in Nova Scotia, Canada. The cause of his death was complications from diabetes.
He was survived by his wife and two daughters. Today, the famous scientist is remembered for his groundbreaking work in sound technology and improving education for the deaf.
His best-known invention, the telephone, forever changed the way humans communicate with each other. Alexander Graham Bell.
History: Alexander Graham Bell. Famous Scientists. Who is credited with inventing the telephone? Im Jahrhundert, also in der Zeit der Erfindung des Telefons haben sich verschiedene Forscher unabhängig voneinander mit diesem Thema beschäftigt.
Und es hat sich gezeigt. Zur Erfindung, Geschichte und zum Urheberstreit kannst du hier noch mehr nachlesen. When Bell spoke into the open end of the drumlike device, his voice made the paper and needle vibrate.
The vibrations were then converted into an electric current which traveled along the wire to the receiver. At age 11 he entered the Royal High School at Edinburgh , but he did not enjoy the compulsory curriculum, and he left school at age 15 without graduating.
In the family moved to London. Alexander passed the entrance examinations for University College London in June and matriculated there in the autumn.
Mabel had become deaf at age five as a result of a near-fatal bout of scarlet fever. Bell began working with her in , when she was 15 years old.
Despite a year age difference, they fell in love and were married on July 11, They had four children, Elsie — , Marian — , and two sons who died in infancy.
In Joseph Stearns had invented the duplex, a system that transmitted two messages simultaneously over a single wire. Inventors then sought methods that could send more than four; some, including Bell and his great rival Elisha Gray , developed designs capable of subdividing a telegraph line into 10 or more channels.
These so-called harmonic telegraphs used reeds or tuning forks that responded to specific acoustic frequencies. They worked well in the laboratory but proved unreliable in service.
A group of investors led by Gardiner Hubbard wanted to establish a federally chartered telegraph company to compete with Western Union by contracting with the Post Office to send low-cost telegrams.
Bell, however, was more interested in transmitting the human voice. Finally, he and Hubbard worked out an agreement that Bell would devote most of his time to the harmonic telegraph but would continue developing his telephone concept.
From harmonic telegraphs transmitting musical tones, it was a short conceptual step for both Bell and Gray to transmit the human voice.
Bell filed a patent describing his method of transmitting sounds on February 14, , just hours before Gray filed a caveat a statement of concept on a similar method.
On March 7, , the Patent Office awarded Bell what is said to be one of the most valuable patents in history. It is most likely that both Bell and Gray independently devised their telephone designs as an outgrowth of their work on harmonic telegraphy.
However, the question of priority of invention between the two has been controversial from the very beginning. Despite having the patent, Bell did not have a fully functioning instrument.

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.
