Edison's Inventions

What were Thomas Edison's top three inventions? The question is harder than you might think. Edison earned 1,093 United States patents for his inventions.

How do you make a filament for the light bulb? What machine can make enough electric power to light up all those bulbs? How do you get electric power to all those light bulbs out there? All these questions have to be answered; all these things have to be invented. That is why each of the inventions below took years of hard work. No wonder Edison said, "Genius is one percent inspiration and ninety-nine percent perspiration!"

These three inventions are considered Edison's greatest: the electric light system,  the phonograph and motion pictures. If Edison had only invented one of these, he would have made an important contribution to the world. But even these top three inventions were not enough for him. Other patents included the alkaline storage battery, improvements to the telegraph, the telephone and the stock ticker, Portland cement and even a substitute for rubber. At Edison's three laboratories (Newark, Menlo Park and West Orange), his "muckers" worked night and day on his many ideas.
