Alexander Graham Bell was an inventor, scientist and teacher who is best remembered for the invention of the phone. He was born on March 3, 1847 in Scotland, and he and his family moved to England in 1865 and in Canada in 1870. He became a US citizen in 1882 when he was able to be a British subject; He later moved to Canada and lived there on August 2, 1922.
Although Alexander Graham Bell is remembered as a very mobile inventor, he also found other devices. Bell developed several Sonic Technologies, including Photophone (1880) and Graphophone (1886). He also developed medical technology. After an American recipe. James A. Garfield in July 1881 Bell collaborated with Professor Simon NewComb to promote shooting from the British British British British office. The couple showed the study in the fall of 1881. Later, Bell turned his mind into air technology. He founded the Aviation Test Community in 1907.
The first phone had two parts: I sent and receive the receiver. The transmitter had three parts – a device such as a drum (a cylinder with a covered head), a needle and a battery. The covered end of the drum device was attached to the needle. The needle was connected to the wire and the battery and the battery was connected to the wire and the receiver. When Bell spoke at the open end of the dance device, his voice made the paper and the needles shake. The vibrations were then converted into the current electricity, which passed the wires into the receiver.

Alexander Graham Bell (born March 1847, Edinburgh, Scotland – died on August 2, 1922, Beinn Bhreah, Cape Breton Island, Nova Scotia, Canada) was an inventor, scientist and deaf teacher who was very successful, in Canada and during the US life. Phonography (copyright in 1886).
Alexander (“Graham” was only added at the age of 11) was born to Alexander Melville Bell and Eliza Grace Symonds. His mother was almost deaf, and his father taught the deaf and influenced Alexander’s future choice as a deaf teacher. At the age of 11, he came to Edinburgh’s royal high school, but did not enjoy the necessary curriculum and left the school at the age of 15 without graduation. In 1865, the family moved to London. Alexander passed the exams to the University of London in June 1868 and was held in the autumn. However, he did not finish his studies because in 1870 the Bell family moved again, this time moving to Canada after the death of Bell Edward’s younger brother in 1867 and older Melville in 1870, all tuberculosis. The family stayed in Branford, Ontario, but in April 1871 Alexander moved to Boston, where he taught at the Boston Deaf School. He also taught the deaf Clarke School in Northampton, Massachusetts and Hartford, a deaf American school in Connecticut.
One of Bell’s students was Mabel Hubbard, daughter of Clarke School’s founder Gardiner Greene Hubbard. Mabel was deaf at the age of five from a nearby Scarlet fever. Bell started working with him in 1873 when he was 15 years old. Despite the differences in ten years, they fell in love with July 11, 1877. They had four children, Elsie (1878-1964), Maria (1880-1962) and two dead sons.

By following his teacher’s profession, Bell also started methods for spreading several phone messages at the same time with one cord – the main purpose of the Telegraph invention and that led to Bell’s invention. In 1868, Joseph Stearns had found a duplex, a system that passed two messages at the same time with one cable. Western Union Telegraph Company, the largest company in the industry, bought Stearns’ duplex rights and hired a well -known inventor Thomas Edison to develop as many shipping methods to prevent competitors from them. Edison’s work ended four times, four Telegraph message systems simultaneously with one cable. Then the inventors are looking for ways that could send more than four; Others together with Bell and his biggest competitor Elisha Gray developed structures that are able to distribute the Telegraph line as at least 10. These are known as horizontal telegrams used bamboo or tuning forms that respond to certain acoustic frequencies. They worked well in the laboratory, but proved to be unreliable service.

The investor group led by Gardiner Hubbard wanted to set up a federal Telegraph to compete with the Western Union with a post office that sends cheap phone calls. Hubbard saw a great promise in a harmonious telegram and supported Bell’s experiments. However, Bell was more interested in conveying a human voice. Finally, he and Hubbard made an agreement that Bell would spend most of his time on a harmonious telegram, but would continue to advertise the telephone idea.

For aesthetic telegrams that send tons of music, it was a short concept step into the clock and gray to spread the sound of a person. Bell introduced the patent, which explained his way to spread the sound on February 14, 1876, a few hours before Gray introduced the cave (fine statement) in the same way. March 7, 1876, the Patent Agency handed over to Bell, who is said to be one of the most important fairs in history. It is possible that both Bell and Gray were independent of their planning of their mobile design as a means of their harmonic electricity workers. However, the primary issue of the discoveries between the two has been controversial from the beginning.

Despite the patent, Bell did not have a fully functional device. For the first time, he made a speech on March 10, 1876, when he called his laboratory stance Thomas A. Watson, and the words Bell wrote in his laboratory description, “Mr. Watson – he comes here – I want to see you”. In the next few months, Bell continued to clean his container to fit the public screening. In June, he showed his phone to the Philadelphia centenary judge, a test witnessed by Brazilian Pedro II and a Scottish physicist Sir William Thomson. In August of the same year, he was moved from Branford to Paris, in Ontario, with Telegraph leadership at the end of the first long phone.
Introduction: Defining Technology: Title: The Evolution And Impact Of Technology: A Journey Through Time And Beyond
Gardiner Hubbard organized a group that founded Bell’s mobile company in July 1877 to sell Bell’s phone. Bell was a technical consultant until he lost his appetite in the early 1880s. Although his discovery made him rich independently, he sold many parts of his warehouse and did not benefit because he was able to maintain in his warehouse. Thus, by the middle of his role, his role in the mobile industry was low.
