Many people think that Thomas Edison invented the light bulb but if we look at the history he was the first one to sign the patent that declared that he will be the only person that can create and make light bulbs. Well now we know that all of us can make light bulbs like the brand philips,AERIN Syska LED Bulb and so much more but if you want to see how this happened we have to take a step back to history. Edison was not the first creator but he improved the safety and the brightness which was definitely a huge change in the history but the first person to make the light bulb was Humphry Davy it did not look like the light bulbs that we use today he used a bank of batteries and two charcoal rods and carbon he connected weirs to the battery and used the carbon which produced light and connected the end of the battery with the charcoal rods that only provided very dim light and only stayed on for the hope of even 1 or 2 min. But that was only the beginning of this grate historic event.When Thomas Edison signed the patent many other people where were angry they argued over the rules of the patent but the person who started the real debate was with the westing house and Nikola tesla the debate was called wars of current it was from 1880 to 1890 it was 10 years long!! On march 13 1895 after tesla and his employees left a fire happened at his laboratory all of his notes were destroyed There was even a rumor that claimed that edison was behind the fire that happened at tesla's lab. Back then many people were scared that electricity was dangerous and could set a fire.It was also very expensive,they had to keep the generator every few 100 meters. The light bulbs were very expensive. It was 1$ back then and that was very expensive. Only rich and big businesses could only afford that.And it would only stay for a short amount of time if you use it too much or even if you have been using it for a long time. At the end Westinghouse and Tesla won the case and Edison also got the credit for his light bulb illuminated in the dark of the torch of the Statue of liberty.Now you know that there is history and truth in every great invention ever.
