Alva Edison (1847-1931) was one of the greatest American inventors.
He was a self-educated American inventor and industrialist, who had
three months of formal education. He was a very persistent and hardworking
inventor with great enterpreneurial skills. Edison's greatest inventions
were - incandescent lamp and phonograph, and he improved and perfected
the telegraph, telephone and motion-picture equipment. His famous quotes
was: " Always keep on the lookout for novel ideas that others have used
successfully. We don't know one millionth of one percent of about anything...
I start where the last man left off... Your idea has to be original,
only in its adaptation to the problem you're working on. A good idea
never was lost. Its possessor may die, but it will be reborn in the
mind of another." He held many patents to his name.
started with his entrepreneurial skills at early age of 12, when he
began selling newspaper and candy; then he worked as a roving telegrapher,
a night operator for Western Union Telegraph Company until 1869, when
he decided to move to New York City in order to pursue with invention
and entrepreneurship. In a year Edison established a workshop in Newark,
N.J. Then he produced the Edison Universal Stock Printer and other printing
telegraphs. In 1876 he set up a research laboratory in Merlo Park. During
that period, Edison with the help of several highly talented engineers-associates
achieved his greatest successes. In 1877 he invented the phonograph,
in 1879 carbon filament lamp. He also improved motion-picture camera,
which was invented by French brothers, Auguste and Louis Lumiere in
been a businessman predominately, Edison ruthlessly fought his competitors.
The most notorious example of that was the "war of currents". It was
well-documented, in that-time-newspapers, the length he went to discredit
Nikola Tesla's alternating current(AS) system, universally used today,
and known as superior technology to Edison's direct current (DC) system.
This "war" resulted in production of the electric chair based on AS
