ThomasEdison

Initially, it was believed that ThomasEdison invented the motion picture camera, but it has since been proven that WilliamKennedyLaurieDickson actually invented it at the Edison laboratories. However, his influence on the history of film stretches far beyond that of instigator. He became a powerhouse of film production and must be given credit for establishing a standard that allowed film to emerge as a mass media and not just a vaudeville novelty.

I have read that, similarly, the credit traditionally given to ThomasEdison for the invention of the LightBulb? is misplaced. I am not competent to assess this claim.

He did invent the filament for the light bulb...I know that.
