Phone (Telephone)


Alexander Graham Bell (1847-1922) was the discoverer of America and teaching for the deaf, and he was known as the inventor of the telephone (telephone).

Born on March 3, 1847, in Edinburgh, Scotland, and was educated at the University of Edinburgh and London. Then in 1870 he moved to Canada and then moved again to America in 1871. In the U.S. he began teaching the deaf and dumb, popularizing the system is called 'visual language'. System developed by his father, Alexander Melville Bell, who shows how the lips, tongue, and throat are used in describing the sound.

In his childhood, he has shown curiosity in a very big world, which led him often to collect plant samples. Together with his good friend who has a grain mill which is also a neighbor, he often makes noise, and one day his father said, "Why do not you make something more useful?" When Alexander Graham Bell was asked, what is needed in doing. And the father of his best friends told me that wheat should be separated with the skin. At the age of 12 years, Alexander made a simple device that combines a rotating paddle brush with a series of nails to separate the wheat with the skin. The equipment can operate properly for years, and as a 'gift', his father gave them a chance to play in a garage (workshop) to create a small 'new discovery'.

Since the age of 18 years, Bell has been researching the idea of how to send and transfer words. In 1874 when he worked on the telegraph, he developed new ideas for the basic telephone. Experiments done with his assistant Thomas Watson finally proved successful on March 10, 1876, when the word was transmitted: "Watson, come here; I want you." (Watson, come here, I need you). A series of demonstrations using telephone, the telephone has been introduced throughout the world and led by the company, the Bell Telephone Company in 1877.
