Alexander Graham Bell (1847-1922) was an inventor from America and also was a teacher for deaf people. He was credited in the field of communication technology, so that thanks to the discovery and now we can communicate each other using a phone without constrained by distance.
Alexander Graham Bell was born in Edinburgh, Scotland, on March 3, 1847. He is a graduate of Edinburgh University, London. In 1870 he moved to Canada and then moved again to United States in 1871. In United States he starts teaching people who are mute and deaf, and popularized the system called ‘visual language’. This system was developed by his father, Alexander Melville Bell that indicates how the lips, tongue, and throat can be used to describe the sound.
In his childhood, he has shown a curiosity on this environment, which causes him to frequently collect some samples of plants. Along with his best friend who has a wheat milling machine and also his neighbors, he is often seen making noise, so one day her friend’s father said to them, “Why don’t you guys make something more useful?”. That time Alexander Graham Bell then asks, what needs to be done. And the father of his best friend tell that wheat should be separated from the chaff.
By these challenges, then at the age of 12 years, Alexander made simple equipment that combines a rotating paddle with a series of brushes from the nails that can serve to separate the wheat from the chaff. The equipment can operate properly over the years, and as a ‘Prize’, the father of his friend gives them the opportunity to play in a small workshop to create a new ‘discovery’.
Since the age of 18 years, Bell has been researching and have an idea about how to transmit and transfer words. In 1874 when he was working on the telegraph, he developed the basic idea for a new telephone. The experiment he did along with his assistant Thomas Watson finally proved successfully on March 10, 1876, when this word was transmitted: “Watson, come here; I want you.” A series of demonstrations of the use of the telephone then has introduced telephone to the world, led by his company, the Bell Telephone Company in 1877.
