Translated:
Thomas Edison is one of the greatest inventors in the world. He was responsible for more than 1000 inventions including the electric light bulb and the phonograph. He also created the world’s first industrial research laboratory. Edison was born in 1847 in Ohio, USA. When he was 10 years old, he set up a small laboratory after he read a science book his mother showed him. In 1869, he borrowed some money and started making inventions. In 1876, he built a new laboratory so that he could spend all his time inventing. He planned to come up with a small invention every 10 days and a “big invention” every six months. He has developed many devices that bring great benefits to human life. He once said that the value of an idea lies in its use. Edison died in 1931, after a remarkable life of dedication.
