Inventor of the Lightbulb
If you can read this, thank Thomas Edison and his patent number 223,898. However, it's true that this famous Thomas Edison invention wasn't totally his own creation. It's actually registered as an improvement to the electric lamp as well as a manufacturing method of the same. Patents can be filed not just for new ideas but for significant improvement to old ones. A British man, Joseph Swan was the original demonstrator of the world's first electric light bulb, and a few men before him patented a light bulb but didn't have the capital to commercialize their ideas. So, Edison purchased the rights to their product. He then work fast and diligently to find ways to make the light burn longer and brighter so it's likelihood of commercial success would be greater. Eventually, in 1880, he perfected a 16-watt incandescent bulb that burned up to 1,500 hours.
