Alexander Graham Bell (1847-1922) was a U.S. inventor and teacher of the deaf, and he is 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 the United States in 1871. In the U.S. he began teaching the deaf and dumb, popularizing the system is called a 'visual language'. System developed by his father, Alexander Melville Bell, who shows how the lips, tongue, and throat are used to describe the sound.
On his childhood, he had been showing curiosity very large in the world, which led him often to collect examples of plants. With his best friend who has a grain mill which is also a neighbor, he often made a fuss, and one day his father said, "Why do not you make something more useful?" When Alexander Graham Bell asked, what needs to be done. And his best friend's father told me that wheat must 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 from the skin.The equipment can operate properly for years, and as a 'reward', his father gives them the opportunity to play in a garage (workshop) small to make a '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 was working on the telegraph, he developed the idea of a new foundation for the telephone. The experiments were done with his assistant Thomas Watson finally proved successful on March 10, 1876, when the word was transmitted: "Watson, come here; I want you". A series of demonstrations using telephone, the telephone has been introduced around the world and led by the company, the Bell Telephone Company in 1877.
