The first electric light bulb was invented by Humphry Davy in 1809, using a carbon arc. Later, in 1841, Frederick de Moleyns patented an early version of an incandescent lamp. However, it was Thomas Edison who, in 1879, improved the design by developing a long-lasting filament, making electric lighting practical for widespread use. Edison’s version used a carbon filament inside a vacuum-sealed glass bulb, significantly extending its lifespan and popularizing electric lighting. #ElectricBulb #Hum

Sir Humphry Davy Electricity Parking Experiment. Sir Humphry Davy, (17 December 1778 – 29 May 1829) was a British chemist and inventor who invented the Davy lamp and a very early form of arc lamp. He is also remembered for isolating, by using electricity, several elements for the first time: potassium and sodium in 1807 and descovery of calcium, strontium, barium, magnesium and boron the following year, as well as for discovering the elemental nature of chlorine and iodine.
