Greatest historical myths-Edison invented the electric light

Edison invented the electric light

Thomas Edison is known as the world’s greatest inventor. His record output - 1,093 patents - still amazes us, over a century later. Astonishing, except for one thing: he didn’t invent most of them. Most Edison inventions were the work of his unsung technicians - and his most famous invention, the electric light, didn’t even belong to his laboratory. Four decades before Edison was born, English scientist Sir Humphry Davy invented arc lighting (using a carbon filament). For many years, numerous innovators would improve on Davy’s model. The only problem: none could glow for more than twelve hours before the filament broke. The achievement of Edison’s lab was to find the right filament that would burn for days on end. A major achievement, but not the first.
