Did Thomas Edison Really Invent The Lightbulb?

In today's era of smartphones, virtual reality glasses and smartwatches, the lightbulb can be considered a primitive device to most. Merely a tungsten filament wrapped around two pieces of carbon rod (not to mention the vacuum sealed glass dome which prevents it from oxidization,) its simplicity makes it an invention which most people overlook. However, did Thomas Edison really invent it?
How Lightbulbs Work
The Carbon Craze
There was, however, one major flaw with its design. The reasoning behind this was that the carbon filament fell apart after a few electric charges were passed through it. Therefore, the bulb was—no pun intended—screwed.
Edison Enlightens the Idea
After hearing about the lightbulb, Edison saw a great fortune which came from its perfection. Therefore, when he was able to do so, Edison recruited a Princeton University student named Francis Moore in order to help with the bulb's design. It was after Edison recruited Moore, however, that lots of bright ideas came to him.
What Francis noticed was that, if a material had low resistance, it would produce less light and crumble in front of somebody's eyes when electricity was passed through it. Then, after experimenting with many various metals and vacuum strengths, Edison finally came up with a viable, cheaper version of the lightbulb which could be mass produced. With a bamboo and carbon inspired filament, he had done it.
If you read about any of the things above, then you should know that the answer to this is one simple, two lettered word-NO. Although he did fine tune the bulb in order to make it a decent source of alternative light, he didn’t really do anything else. However, if you read the story, it’s undoubtedly fascinating to think that, hundreds of years ago, people could have come up with a modern day source of electrical light which is widely used today.
