EOTO 2
Before I started this research on the lightbulb, I knew that it was one of the most significant inventions ever created. We all learn about these things when we are younger in school, but we have never gone into much depth from the beginning of time till the present day. Life before the light bulb was a much simpler time, and people would use the sun to know that during the day, you would do your job, or if you were a child, do activities. In those nights, there was never such a thing as a light bulb, and the source of light would be candles or oil lamps. It was always a struggle to have constant light during the night, until the light bulb was created by Thomas Edison in 1879
Thomas Edison was the first person to officially create the first light bulb, but there were definitely people who contributed to the advancement of light over time. Humphry Davy and Joseph Swan experimented a lot with light before the light bulb was officially created. Humphry Davy created an electric battery in 1800 while he was putting the electricity to the test. He would use the battery and put wires and carbon to it, which would ultimately work, but the carbon could only stay lit for a certain period of time. Joseph Swan tried to do a similar thing in 1860 using carbon paper filament, but it burned too quickly as well, and was a great improvement from Davy's work.

What Edison did that stood out and was different from the other two was ultimately the thing that they were missing. Edison tried thousands of combinations and could not get it right until he finally found the perfect filament. He uniquely found out that Davy and Swan's carbon filament worked, but it needed to be in an oxygen-free bulb. This bulb would glow for 40 hours, which in 1879 was the first of its kind and made a remarkable impact. In late 1880, Edison eventually made a bulb that lasted 12,000 hours, and he would go on to get his second patent, which was for incandescent light bulbs.
In 1904, Willis Whitney invented something that allowed the filament to burn longer and not the inside of the bulb from getting dark. This was a stepping stone to what we know now as the light bulb created by William Coolidge, and he made a tungsten filament, which completely changed the world. This invention has completely changed the world, and it has greatly impacted people, no matter their social status. Neither the rich nor the poor realize how lucky we are to have light, and we take it for granted every single day. No human would be able to do what they do without light bulbs. There would be no offices, schools, or homes with constant light. Our world would look completely different, and there would be no advancements in technology, architecture, or health. The light bulb, personally, has been the greatest invention of all time, and it has made the world into what we know it is today.
