After thousands experimental, Edison finally in 1879 at the end of the first show out of the electric light. In 1889, he developed the first actual films to be shown. In his later years, this Menlo Park Wizards "and known for the elderly are enormous respect for the public. the
Edison hung on the wall behind the bacteria with his invention of photomicrography shooting photos
who brought electric light to the world, phonograph, movies, and more than 100 inventions, the great man in 1931 10 January 18, 2009, died at 82 years old. However, so far no one can break he holds the record of 1099 patents for their invention, people call him the king of the invention.
