American inventor Thomas Edison demonstrated incandescent lighting to the public for the first time on 31st December 1879. He went on to open the first electric lamp factory a year later.
Edison had invented his light bulb a couple of months back. Actually, electric bulbs had been in existence before Edison showed an interest in them and changed the world by developing bulbs that last long.
Joseph Swan, a British physicist, is generally credited for inventing the light bulb. He was also the first to patent them and use them at his house and the Savoy Theatre in London, the first home and public building to be lit by electricity, respectively.
