In 1802,Humphry Davyinvented the first electric light. He experimented with electricity and invented an electric battery. When he connected wires to his battery and a piece of carbon, the carbon glowed, producing light. Did Thomas Edison invent the lightbulb on his own? Edison did not actually ...
Thomas Edison immediately set up a shop in Newark. He improved the system of automatic telegraphy (telegraph machine) that was in use at that time and introduced it into England. He experimented with submarine cables and worked out a system of quadruplex telegraphy by which one wire was made ...

including the replacement of carbon filaments with metal one. While Alexander Lodygin first patented the tungsten filament in the 1870s, it would be another 30 years before manufacturing technology made this material economical to work with.
