1. Childhood

  Edison was born on February 11, 1847 in Milan, Ohio.  He is the youngest of seven siblings, son of couple Samuel Ogden Edison Jr.  and Nancy Matthews Elliott.

  Little Edison only went to school for a few weeks before his mother withdrew him and decided to teach him himself.

  At that time, his teacher warned that Edison was considered a student who was often left behind, was not smart, and was considered not talented.

  During his mother's teaching, Edison's education was obtained from the School of Natural Philosophy by RG Parker and The Cooper Union for the Advancement of Science and Art.

  At the age of 11 years, Edison who learned self-taught showed great curiosity by reading various books


2.Youth

Thomas has poor hearing not because he is truly deaf, but rather he has a hearing loss.  Some said that this hearing loss was due to illness and some said it was due to an accident (the station officer hit Thomas because of a fire on the train due to his laboratory).  However, Thomas did not complain about it or make it lacking.  He considers that to be an advantage because he has more time to think than to listen to empty talk.

 Thomas registered his first patent for an electric vote recorder, but no one bought it.  Finally, Thomas also decided to make a tool that attracts people to buy it.  He switched to commercial equipment.  Thomas managed to develop a stock ticker and sell it to a company for $ 40,000.  With this money, he built a laboratory and company in Menlo Park, New Jersey

3.Incandescent Light Experiment

In 1877, Thomas devoted his energy, time, and money to the experiment of making incandescent lamps.  The problem is he must be able to find materials that can glow, but do not burn when electrified.  Thomas has experimented with 6,000 different ingredients.  Finally, on October 21, 1879, created the first electric light that can be lit for 40 hours.  In 1890, he founded the General Electric company.

 Regarding this experiment, Edison once protested the newspaper that wrote the headline entitled "After 9,955 Failures to Find an Incandescent Light Bulb, Edison Finally Successfully Found a Lighting Lamp."  Edison has finally succeeded in finding a light that is on. "

4. Death and funeral

Edison's death died on 18 October 1931 in the age of 84 years in his residence, Glenmont, at Llewellyn Park, West Orange due to diabetic complications. The company and community around the world turn off the lights and electricity as a form of honor to the inventor.
