Bell Erfinder

Vor Jahren gelang Graham Bell eine bahnbrechende Erfindung: Er entdeckte, wie man Schallwellen in elektrische Schwingungen. Alexander Graham Bell war ein britischer, später US-amerikanischer Audiologe, Erfinder und Großunternehmer. Er gilt als der erste Mensch, der aus der Erfindung des Telefons Kapital geschlagen hat, indem er Ideen seiner Vorgänger zur Marktreife.

These include Meucci, who accused Bell of stealing his ideas. Antonio Meucci filed a patent caveat for a telephone device in December of Patent caveats according to the law were "a description of an invention, intended to be patented, lodged in the patent office before the patent was applied for, and operated as a bar to the issue of any patent to any other person regarding the same invention.

They are no longer issued. Patent caveats were much less costly than a full patent application and required a less detailed description of the invention.

The U. Patent Office would note the subject matter of the caveat and hold it in confidentiality. He also conducted sheep-breeding experiments at his estate to see if he could increase the numbers of twin and triplet births.

In , he hastily constructed a metal detector as a way to try and locate a bullet lodged in President James Garfield after an assassination attempt.

He would later improve this and produce a device called a telephone probe, which would make a telephone receiver click when it touched metal.

And when Bell's newborn son, Edward, died from respiratory problems, he responded by designing a metal vacuum jacket that would facilitate breathing.

The apparatus was a forerunner of the iron lung used in the s to aid polio victims. Other ideas he dabbled in included inventing the audiometer to detect minor hearing problems and conducting experiments with energy recycling and alternative fuels.

Bell also worked on methods of removing salt from seawater. These interests may be considered minor activities compared to the time and effort he put into making advances in manned flight technology.

By the s, Bell had begun experimenting with propellers and kites, which led him to apply the concept of the tetrahedron a solid figure with four triangular faces to kite design as well as to create a new form of architecture.

McCurdy, four young engineers with the common goal of creating airborne vehicles. By , the group had produced four powered aircraft, the best of which, the Silver Dart, made a successful powered flight in Canada on February 23, Although working with the deaf would remain Bell's principal source of income, Bell continued to pursue his own studies of sound throughout his life.

Bell's unceasing scientific curiosity led to the invention of the photophone , a device that allowed for the transmission of sound on a beam of light.

Despite being known for his invention of the telephone, Bell regarded the photophone as "the greatest invention I have ever made; greater than the telephone.

With the enormous technical and financial success of his telephone invention, Bell's future was secure enough so that he could devote himself to other scientific interests.

After his first visit to Nova Scotia in , Bell set up another laboratory there at his estate Beinn Bhreagh pronounced Ben Vreeah , near Baddeck, where he would assemble other teams of bright young engineers to pursue new and exciting ideas heading into the future.

Their experiments produced such major improvements in Thomas Edison's phonograph that it became commercially viable. Their design, patented as the Graphophone in , featured a removable cardboard cylinder coated with mineral wax.

Bell spent the last decade of his life improving the designs of hydrofoil boats. In , Bell and Casey Baldwin built a hydrofoil that set a world water-speed record that was not broken until Bell died of complications arising from diabetes and anemia on August 2, , at his estate in Cape Breton, Nova Scotia, at age As the funeral ended, all of the more than 14 million telephones in the United States at the time were silenced for one minute.

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.

Then in they sold their patents to the American Graphophone Company, which later evolved into the Columbia Phonograph Company.

Bell used his proceeds from the sale to endow the Volta Laboratory. Bell undertook two other noteworthy research projects at the Volta Laboratory.

In he began research on using light as a means to transmit sound. 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.

The question of whether Bell was the true inventor of the telephone is perhaps the single most litigated fact in U.S. history, and the Bell patents were defended in some cases. Meucci was a defendant in American Bell Telephone Co. v. Globe Telephone Co. and others (the court's findings, reported in 31 Fed. Rep. ). Alexander Graham Bell (/ ˈ ɡ r eɪ. ə m /; March 3, – August 2, ) was a Scottish-born inventor, scientist, and engineer who is credited with inventing and patenting the first practical telephone. He also co-founded the American Telephone and Telegraph Company (AT&T) in The Bell modem or Bell dataset was the second commercial modem for computers, released by AT&T Corporation in It allowed digital data to be transmitted over regular unconditioned telephone lines at a speed of bits per second. Bell was the first person to patent the telephone, and his company was the first to bring telephone services successfully to the marketplace. But people are passionate in putting forward other inventors who deserve the credit. These include Meucci, who accused Bell of stealing his ideas.
