"Be brave as your fathers before you. Have faith and go forward."
These were the words of Thomas Alva Edison, the great American scientist and businessman, who was one of the most prolific inventors in history. Edison held 1,093 U.S. patents in his name, as well as many patents in the United Kingdom, France, and Germany.
His inventions in the mass communication and telecommunications field, including the phonograph; motion picture camera; and a long-lasting, practical electric light bulb; propelled the world into the 20th century.
