Nikola Tesla
Edison had a habit of getting subordinates and others to work out the kinks in an invention and then claiming them as his own.
As I understand it, Edison actually bought a patent from Canadian inventors who had developed a working light bulb. There's more on that here: https://en.wikipedia.org/wiki/Henry_Woo ... nventor%29.
It could be argued that, since Edison bought the patent, and then made changes to the design to make it commercially viable, he in a way did invent the light bulb. Perhaps it should be phrased that he invented the "first commercially viable light bulb". I don't think too many people would quibble about that.
