This Snapshot is a biography. A biography tells a person's life story. It is written by someone else. Alexander Graham Bell was born in Scotland in 1847. His father taught people how to speak well. His mother was deaf. But she taught him to play the piano. From his early years, Alexander was good in music and science.
More than anything else, he was interested in sound. He also liked to invent things. In 1871, he moved to Boston . He taught at a school for deaf students. At night, he did experiments with sound.
Alexander wanted to learn more about electricity. In 1874, he met Tom Watson, who knew about it. So Alexander and Tom worked together on experiments.
Alexander stopped teaching. He wanted to invent a machine that let voices go from one place to another. He and Tom built many different machines.
Finally, in 1876, Alexander spoke to Tom through the first telephone. They worked to make their telephone better. Soon they built one that could send voices many miles. In 1915, they made the first telephone call across the United States.
Alexander Graham Bell and his inventions changed the way people communicate even today.
