This machine was invented by Alexander Graham Bell also he is one of the famous inventers around the world. Telephone was invented to make contact between people easily. His birth and his family Alexander Graham Bell was born in 3 March 1847 .. Edinburgh Scotland. His mother, was deaf, she was a musician and a painter of portraits. His father, who taught deaf people how to speak,. Graham, or "Aleck", as his family called him, was interested in working with the deaf throughout his life… His life He only attended school for five years; from the time he was 10 until he was 14 years old, but he never stopped learning. He read the books in his grandfather's library … The first step ( the main idea ) When he was a teen-ager, he and his brother Melly used the voice box of a dead sheep to make a speaking machine that cried, "Mama!" This created even more interest in human speech and how it worked. Move his family to Canada his two brothers died of tuberculosis . Alexander Graham Bell himself had the disease and his father moved the family to Canada looking for a better climate in which to live. His Marriage Two years later he went to Boston to open a school for teachers of the deaf and then became a professor at Boston University. It was at this time that he met Mabel Hubbard, one of his students who were 10 years younger than he. Mabel had become deaf at the age of four due to scarlet fever. Five years later they were married. They have (4) Children Two sons who died in infancy and two daughters His invention of the telephone Thomas Watson became an associate of Bell. He made parts and built models of Bell's inventions. One day while they were working Bell accidently heard the sound of a plucked reed * coming over the telegraph wire. Watson had been tuning the metal reeds in the next room. Bell drew up a plan for the telephone and they continued to experiment. The next day he transmitted the famous words, "Mr. Watson, come here. I want you!" A few months later on Feb. 14, 1876, he applied for a patent on his telephone He knew he would have to work quickly to get the patent * because other people were also trying to make an invention to transmit the human voice. Elisha Gray claims he too invented the telephone, but Bell got to the patent office an hour or so before he did. It is said that Antonio Meucci also succeeded with the invention before Bell. Because Bell had the patent, he had the right to be the only one to produce telephones in the U.S. for the next 19 years. He showed the invention to Queen Victoria of England and she wanted lines to connect her castles. By 1917, nearly all of the United State had telephone service. He continued to invent other things. He developed a method of making phonograph * records on a wax disc. He made an iron breathing lung, and a device for locating icebergs at sea. He experimented with sheep. He was interested in kites that could lift a man, and he invented a hydrofoil * which set a world speed record of over 70 miles per hour. Death Died 2 August 1922 (aged 75) He died patient illness pernicious anemia Conclusion In conclusion, Telephone is one of the important facilities in our life and has many benefits such as connecting people together. Also it is helped people to know about the news and what is happening in the world. Finally, today's people don't need to use letters.
