Edison was born in Milan, Ohio, USA, and is known as "the king of inventions in the world". He has more than 2000 inventions, including phonograph, movie camera, tungsten light bulb, etc., which have great influence on the world. In the United States, Edison has 1093 patents, while his patents in Britain, France, Germany and other places have accumulated more than 1500.

Edison's early experience:

From 65438 to 0857, Edison became interested in chemistry. He did experiments in the cellar at home according to the textbook, which often caused frequent accidents.

1859, in order to have enough money to buy chemicals and experimental equipment, Edison began to look for a job to make money. After some efforts, he found a job selling newspapers on the train. Every day, he goes back and forth between Port Huron and Detroit. He sells newspapers and does fruit and vegetable business, but whenever he is free, he will go to the library to read books.

186 1 year, Edison bought an old printing machine with the money he earned from selling newspapers, and began to publish Herald Weekly, edited by himself. The inaugural issue was printed on the train. He is not only the president, journalist and publisher, but also a printer and newsboy. There is a lounge on the train where Edison works. Because the air was not circulating, no one went there to rest and became an empty room.

Because Edison travels by train every day and comes home late every day, he often feels that time is not enough. Edison thought that if he changed the lounge into a laboratory, he could do experiments on his way back to Port Huron. With the consent of the conductor, the empty lounge became Edison's laboratory.
