Light Bulb Grolier Multimedia
1,351 wordsOn October 22, 1879 Thomas Edison created the electric light or what we know of it today as the light bulb. To make a statement like this that Thomas Edison invented the light bulb is both a huge hyperbole and a huge understatement all at the same time. A more correct view is that he perfected a practical light bulb and that his real plan and accomplishment was the invention of an electrical system to produce and distribute electrical power. He did in fact invent a light bulb with the correct fi...
