Early life. Thomas Alva Edison was born in Milan, Ohio. When Edison was seven years old, he moved with his family to Port Huron, Michigan. Edison started school late because of an illness. Three months later, Edison was removed from school, because he could not pay attention to his teacher. His mother, who was a teacher in Canada, taught Edison at home. Edison's mother helped him become motivated for learning, and he was a good student to her.
When Edison was twelve years old, he contracted scarlet fever. The effects of the fever, as well as getting picked up by the ears by a train conductor, caused Edison to become completely deaf in his left ear, and 80 percent deaf in the other. He learned Morse code of the telegraph, and began a job as a "brass pounder" (telegraph operator). At age sixteen, Edison made his first invention, which was called an "automatic repeater." It sent telegraph signals between unmanned stations, allowing almost anyone to translate code easily and precisely at one's own speed and convenience.

In 1876 Edison used the money from his inventions to start his own laboratory in New Jersey. In 1877~78, he invented there the carbon microphone, which made the sound for Alexander Graham Bell's new telephone invention louder. In 1877, Edison invented the phonograph, the first machine that could record and play sound. The phonograph made him internationally famous. In 1879, Edison made a light bulb that lasted longer. Another invention, the electric power distribution network, lasted even longer.
