Thomas Alva Edison

Thomas Alva Edison was born February 11, 1847 in Milan, Ohio. When he was 10 he had

set up a small chemical laboratory in the cellar of his home after his mother had given him

an elementary physical science book. He had found science very interesting and soon

operated a homemade telegraph set. In 1868 he got a job in Boston as an expert night

operator for Western Union Telegraph Company. He had borrowed a small sum from an a

friend and gave up his job in 1868 and became a free-lance inventor, taking out his first

patent for an electrical vote recorder.

In September 1878, after having viewed an exhibition of a series of eight glaring

500-candlepower arc lights, Edison announced he would invent a safe, mild, and

inexpensive electric light that would replace the gaslight in millions of homes. Some of

New York's leading financial figures joined with Edison in October 1878 to form the

Edison Electric Light Company. On October 21,1879, Edison demonstrated the carbon-

filament lamp, supplied with current by his special high-voltage dynamos. Three years

later, the Pearl Street central power station in downtown New York City was completed,

initiating the electrical illumination of the cities of the world. The in 1887 Edison moved

his workshop from Menlo Park to West Orange, New Jersey, where he built the Edison


This had helped many people, including factories. The lamps that Edison created

had lit up whole cities, quickening the pace of city life. Factories were able to remain open

after dark. Although the light bulb had many good effects, it had bad ones too. A lot of the

candle factories were put out of business, which means that a lot of people were laid off.

Many different inventions were created durning the Industrial Revolution.

Sometimes I wonder what the world would be like if these inventors had not created their

inventions. These inventions transformed the world into what they are today.
