Er gilt als der erste Mensch, der aus der Erfindung des Telefons Kapital geschlagen hat, indem er Ideen seiner Vorgänger zur Marktreife weiterentwickelte. Alexander Graham Bell - Erfinder des ersten funktionsfähigen Telefons Alexander Graham Bell war ein Sprachtherapeut, Erfinder und später auch ein Großunternehmer. Er wurde am 3. März in Edinburgh (Schottland) in einer Gelehrtenfamilie geboren.
Alexander Graham Bell Erfindungen Doch er hat nie versucht, seine Innovation patentieren zu lassen. Nachdem Alexanders Brüder Edward und Melville beide an Tuberkulose gestorben waren, siedelten Alexander und seine Eltern nach Kanada über, wo der Vater ein besseres Klima erhoffte Familienspiel eine Lehrtätigkeit aufnahm. Zwar scheiterten diese Versuche, doch hatte Bell damit die Voraussetzungen für die Konstruktion eines funktionierenden Telefons geschaffen. Die Ersten Versuche und das erste Telefonat. meldet Alexander Graham Bell sein Telefon zum Patent an und verbesserte es immer weiter, bis es im Jahre als Telefon praktisch einsatzfähig war. So konnte er dann die erste transamerikanische Sprechverbindung zwischen San Franzisko und New York einweihen. Im Juli gründete Bell die „Bell Telephone Company". In den USA jedoch hat sein Apparat einen hoch interessierten Anhänger gefunden: den Taubstummen-Lehrer Alexander Graham Bell. Der hat sich ein Reis-Telefon besorgt und arbeitet seither damit.

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.

Some of his other notable inventions were: The metal detector: Bell initially came up with this device to locate a bullet inside of assassinated President James A.

Photophone: The photophone allowed transmission of speech on a beam of light. Graphophone: This improved version of the phonograph could record and play back sound.

Audiometer: This gadget was used to detect hearing problems. Eugenics In , Bell was given the controversial title of honorary president at the Second International Congress of Eugenics.

Successful ideas are the result of slow growth. He wants to improve whatever he sees, he wants to benefit the world; he is haunted by an idea.

The spirit of invention possesses him, seeking materialization. Im Jahre wanderte er mit seinen Eltern nach Nordamerika aus. Hier beschäftigte er sich ab auch mit akustischen Experimenten zur Aufzeichnung von Schallwellen.

Er versuchte sie sichtbar zu machen, um auch Gehörlosen eine optische Sprachkontrolle zu ermöglichen. Zwar scheiterten diese Versuche, doch hatte Bell damit die Voraussetzungen für die Konstruktion eines funktionierenden Telefons geschaffen.

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.

He first produced intelligible speech on March 10, , when he summoned his laboratory assistant, Thomas A. Watson—come here—I want to see you.

In August of that year, he was on the receiving end of the first one-way long-distance call, transmitted from Brantford to nearby Paris, Ontario, over a telegraph wire.

Although his invention rendered him independently wealthy, he sold off most of his stock holdings in the company early and did not profit as much as he might have had he retained his shares.

Thus, by the mids his role in the telephone industry was marginal. By that time, Bell had developed a growing interest in the technology of sound recording and playback.

Although Edison had invented the phonograph in , he soon turned his attention to other technologies, especially electric power and lighting, and his machine, which recorded and reproduced sound on a rotating cylinder wrapped in tinfoil, remained an unreliable and cumbersome device.

In the French government awarded Bell the Volta Prize, given for achievement in electrical science. Bell used the prize money to set up his Volta Laboratory, an institution devoted to studying deafness and improving the lives of the deaf, in Washington, D.

There he also devoted himself to improving the phonograph. By Bell and his colleagues his cousin Chichester A. Bell and the inventor Charles Sumner Tainter had a design fit for commercial use that featured a removable cardboard cylinder coated with mineral wax.

They called their device the Graphophone and applied for patents, which were granted in The group formed the Volta Graphophone Company to produce their invention.

Antonio Meucci, italienischer Wissenschaftler, war der Erste, der das Gerät entwickelte. Alexanders erste Erfindung war dem Schimpfen von Ben Herdmans Vater seinem besten Freund zu verdanken, als er ihnen erzählte, warum sie nichts Nützliches getan hatten.

Als Bens Familie in einer Mühle arbeitete, mussten sie die Weizenrinde entfernen und es war eine sehr komplizierte Arbeit.

Zu dieser Zeit, mit nur 12 Jahren, schuf Alexander eine Vorrichtung, die rotierende Paletten mit den Nagelbürstensystemen kombinierte und so eine Maschine schuf, die die Weizenrinde entfernte.

Im Jahr schufen Alexander und andere Wissenschaftler den harmonischen Telegraphen, ein Gerät, das mehrere simultane Nachrichten über Töne unterschiedlicher Frequenzen übertragen sollte.

Aus dieser Erfindung entstand die Idee, ein anderes Gerät von besserer Qualität und besserer Kommunikation herzustellen: das Telefon kam an.
