Thomas Alva Edison
Thomas Alva Edison, a hugely successful inventor and businessman, created the first marketable incandescent lightbulb in 1879 in the State of New Jersey in the U.S. Throughout the late 1870’s Edison dedicated his focus to coming up with an economically friendly and safe electric lightbulb that could replace all the gas lighting systems created by scientists for the previous 50 years. Up until the invention of lightbulbs, the only source of lighting came from gas which was not healthy or clean, not to mention dangerous and a cause of pollution.
However, historians say he was not the first or the only inventor to try and produce a successful lightbulb that would be commercially practical. Edison is credited with the invention of the lightbulb due to the fact that his version was able to outdo any others created prior with its enduring incandescent material, superior vacuum and material of a high resistance for the filament.
Edison was very dedicated to creating the first lightbulb to be “commercially practical”, he trialled several different materials, he worked on perfecting the electrical circuit, creating a vacuum to keep the oxygen out so prevent fires and focused on making it as durable and long-lasting. After years of hard work, he finally created a bulb that beat out all the other bulbs existing in that time.
To this day lightbulbs are still as useful, if not more than they were when they were created. They have obviously been improved over the years and continue to effect the world and the way society lives in a positive way. Lightbulbs allow longer working hours so more money is being made, the times before sunrise and after sunset can be more productive due to the fact there are other light sources on hand at all times. This invention has changed the way we go about our daily life, without it we would be left in the dark.
