Thomas Alva Edison was the inventor of the U.S. and is one of the greatest inventors in history. Edison began working at a very young age and continued working until his death. During his career, Thomas Alva Edison had patented some inventions of 1093, including the electric light bulb and the gramophone, as well as film cameras. These three findings raise major industries for the power industry, recording and film that ultimately affect the lives of people around the world. He is also known as the inventor of applying the principle of 'mass production' for his discoveries.

The first light bulb
Edison himself gained his expertise in the field of electricity and telegraphy (the telegraph for communication) in the teen years. In 1868, at the age of 21 years, he has developed and patented the discovery in the form of a recording telegraph machine.

The days of childhood, Edison only attended a formal school for three months, then all his education from his mother who taught Edison at home. Edison Edison mother teaches reading, writing, and mathematics. He also often gave and read books for Edison, among other books from authors such as Edward Gibbon, William Shakespeare and Charles Dickens.

Edison at age 12, earn revenue by selling newspapers and working papers, apples, and candy at a railway track. At that age, too, Edison had lost almost all hearing because of illness, the disease makes it a half-deaf. Edison once wrote in his diary: "I've never heard a bird sing since I was 12 years old."
At the age of 15, Edison, while still selling, bought a small printing press used to further mounted on a car trunk. Then he printed his own newspaper, Weekly Herald, which printed, edited and sold in the spot he was selling.


In the summer of 1862, Edison rescued a three-year-old boy who almost hit by a car. The father of a child who was saved was the head of the train station in place to sell. And as gratitude, head of the station taught Edison how to use the telegraph. After five months of studying the telegraph, Edison worked as a telegraph for 4 years. Nearly all the salary he earned was spent in building a wide range of laboratory and electrical equipment.


Edison was very happy to learn something and read the books there. Of all the learned, Edison applied the lessons in a way little experimenting in the laboratory. Edison lived in the laboratory, only sleep four hours a day, and eating of food carried by the assistant to the laboratory. Edison conducted experiments and experiments continued until his discoveries to be perfect. Perhaps a suitable word to describe the brilliance Edison: "Genius is 99% perspiration"
