~ Thomas Edison .... in  1931 ~

  Thomas Alva Edison is one of the greatest inventors in history and was responsible for more inventions than any other inventor. He created the first research laboratory, which he called The Invention Factory, probably one of his greatest achievements. Altogether he took out patents on 1093 inventions. Some of his inventions developed and improved other people's.

Edison was born in Ohio in the USA in 1847. At school his teacher thought his ideas were crazy and that he might have a learning difficulty. After that, his mother taught him at home. He was full of curiosity and she encouraged him to learn things for himself. He made working models of a steam engine and steam-powered sawmill, and experimented with chemicals.
He was a good businessman all his life. As a child, he grew vegetables and sold them in town. At 12 he got a job selling newspapers on a train, and, at 15, started his own weekly newspaper, which he printed on an old printing press on the train.
He worked as a telegraph operator and in 1869, at 22, he moved to New York where he worked for a gold company. When the machine that printed gold prices broke down, Edison fixed it, then invented a machine that did the job better. This invention made him a lot of money, and with it he set up his own workshop where he manufactured these machines, as well as telegraph machinery.
