As much as I love Tesla; I’m sorry but, no. Edison did not invent the light bulb but, neither did Tesla, not by a long shot. Sir Humphry Davy did the first documented research on what became the precedent of the light bulb. In 1802. Nearly 80 years before Edison began his research on the light bulb. The world is far, far, stranger and history is far more convoluted than we give it credit for.
