DOUG JOHNSON: Welcome to American Mosaic in VOA Special English. I'm Doug Johnson. Today we answer a question about the inventor of the telephone. Out listener question this week comes from Vietnam. Le Thuy Kieu wants to know about Alexander Graham Bell. The inventor was born in Edinburgh, Scotland in eighteen forty-seven. From an early age, Aleck liked to make new things and find new ways of doing work. He was also interested in art, poetry and music. He taught himself how to play the piano. His mother's increasing deafness led the young man to study acoustics -- the way we hear and how sounds are made. He also found a way to help his mother hear better. Instead of speaking into her ear, he spoke toward the top of her face. He also carefully formed the words he spoke. Alexander Graham Bell believed one day machines would be invented to help deaf people hear and speak. He did not like the idea of sign language. For most of his life, Bell worked with deaf people. In eighteen seventy, the family moved to Canada. The next year Bell moved to Boston, Massachusetts, to teach at a school for the deaf. Bell had begun experimenting with electricity and sound when he was eighteen years old. At that time he invented what he called his "harmonic telegraph." This electrical machine could send and receive "beeps" and other sounds over a wire. But it was not until March tenth, eighteen seventy-six that Bell was able to send the human voice over a wire. That moment is famous. Alexander Graham Bell was in one room. His assistant, Thomas Watson, was in another. The inventor said into the device, "Mister Watson, come here. I want to see you." Watson heard him clearly. The telephone was born. Bell was twenty-nine years old. Bell Telephone Company made Alexander Graham Bell a rich man. But he spent his whole life continuing to study and invent. Bell experimented with devices that could find bullets and other metal in the body. He developed a machine to aid breathing. He was also interested in vehicles that could move in air and on water. Alexander Graham Bell died in Nova Scotia, Canada, in nineteen twenty-two. He was seventy-five. DOUG JOHNSON: I'm Doug Johnson.
