Thomas Edison was born the seventh - and last - child of his family in the town of Milan, Ohio. When he was a young boy, he showed remarkable ability that set him apart from his classmates. So after only three months in school, his mother, a teacher, decided to instruct him at home. Edison became a voracious reader and was particularly interested in chemistry and electricity. He constructed a make-shift laboratory in the basement of his house to conduct various experiments on his own.

In order to buy more chemicals and apparatus for his laboratory, Edison got a job selling newspapers and snacks on board the Grand Trunk Railway. He was then twelve years old. When he was off duty, he ploughed the shelves of the Detriot library. With the permission from the railway authorities, he set up a printing station in the baggage compartment and began publishing his own newspaper, the `Weekly Herald'. His business was good and soon the young entrepreneur began to employ other children to work for him.

To allow himself more time for his experiments, Edison relocated his basement laboratory to the baggage compartment. Unfortunately, a fire ignited by a jar of phosphorous led to its closure by a very angry train conductor.

In 1862, Edison saved a boy who was in danger of being overrun by an oncoming train. The boy's father was so grateful that he offered to teach Edison telegraphy. Telegraphy was at that time an important means of communication and operators were in great demand. Edison soon established himself as one of the premier operators in the United States.

Edison worked untiringly. At the age of twenty-three, he set up an engineering firm in New Jersey. During the next six years, he invented the mimeograph and made improvements on the telegraph and the typewriter. His creations are varied. Some of his most notable contributions to society included the development of the incandescent light bulb, the phonograph and the movie camera.

It was said that as Edison grew older, he became increasingly rigid and autocratic. These traits hindered the promotion of his inventions. He also lost millions of dollars on projects which were technologically very impressive but financially not viable.
