1847-1931 EDISON
Versatile inventor Thomas Alva Edison was born in 1847 in Milan, Ohio, United States. Only three years of formal education he received, after it he was kicked out of school because the school considers this kid so stupid.

His first creation, electronic sound recording made when she was twenty-one years. Her work was not sold. After that he earned the manufacture of equipment that are expected to be able to be sold in the market, shortly after he managed to make an electronic voice recorder, he discovered and perfected the telegraph machine that automatically prints the letter, which sold for 40,000 dollars, a huge amount at that time. After that, he queued like finding new work and in a short time Edison was not only famous but also rich. Perhaps, the most original inventions are patented machine LPs in 1877. However, more famous in the world of it is the development of a practical incandescent light bulb in 1879.

Edison was not the first to create a system of electric lighting. A few years earlier lamp with an electric current has been used for lighting street lamps in Paris. However, following the Edison incandescent bulb power-sharing system developed allows for a practical electric lighting in the home. In 1882, the company began producing electricity for homes in New York, and in a short time has spread throughout the world.

With the establishment of the first electric company for lighting homes, Edison means already laid the groundwork for the development of large industry. The use of electric power is not just for illumination but for all aspects of household needs, ranging from televisions to washing machines. Furthermore, the usefulness of electricity through distribution networks established Edison itself encouraged the use of electricity for the industrial sector.

Edison also made a major contribution remarkable for the development of film cameras and projectors. He made important improvements phone (carbon transmitter improve the clarity of hearing), improvements in the field of telegraph, and typewriter. Among other inventions include a dictation machine, coffee machine and a battery-driven storage. Arguably, Edison designing more than 1,000 inventions, an amount that is truly absurd.

One very surprising because productivity is due at the beginning of his career he built a laboratory investigation in Menlo Park, New Jersey. That's where he brought together a group that is capable of helping maker. It is the forerunner of a laboratory investigation later imitated by so many industries. Edison beginner modern laboratory, a center that is fully equipped investigation where so many people work with a team, is also an important result of his work, though of course something that he can not patented.

Edison is not a mere inventor; He was also involved in organizing various fabrication and industrial companies. The most important of which eventually transformed into the General Electric Company.

Although the carriage he was not a pure scientist, Edison make a scientific discovery. In 1882 he discovered that in a state approaching a vacuum, electric current can be flowed between the two wires are not touching each other. This phenomenon - called Edison's invention - not only has an important theoretical purpose, but also has practical use meaningful sense. This lead to the development of vacuum tubes and the foundation of the electronics industry.

Almost all my lifetime, Edison suffered from weak hearing. But, even so, he is more than able to overcome it with hard work awesome. Edison married twice (his first wife died young), has three children from each wife. He died in 1931 in West Orange, New Jersey.

There is no disagreement about the talent Edison. Everyone agreed that he was the great inventor of genius who ever lived. Rows of his findings are very useful considered shocking and make knee shivering, although it may be partly developed by others within thirty years. However, if we consider his personal discoveries, would appear to us that none of it has a decisive significance. For example, an incandescent bulb, although widely used, is not irreplaceable items in the modern world. The evidence suggests, lighting comes from radiation and scattered out in the form of light, which works on the basis of scientific principles are completely different, is also widely used by people, and in our daily lives not make any difference if we do not use incandescent light bulbs at all. Indeed, before the use of electric lighting, candles, oil lamps, and gas lamps already generally regarded as satisfactory lighting levels.

LPs tool is an ingenious invention, but nobody considers that the tool has been able to change our daily lives as well as the role that served the radio, television or telephone. Furthermore, in recent years, it has to be created sound recording device with an entirely different method, such as a magnetic tape cassette. And if there is no machine LPs, it was not anything. Many of Edison's patents relating to the improvement of equipment, have actually been discovered by someone else first, even in the form that had been made. Improvements in this - although much help - can not be regarded as an important meaning in the series of historical movements in general.

However, although none of the findings Edison-shattering importance, is also useful to remember that he did not just create a tool, but more than a thousand. On the basis of this consideration I put Edison higher than such illustrious inventor Guglielmo Marconi and Alexander Graham Bell.
