Re:Who invented the lightbulb? by Joker_vD on Tuesday September 15, 2020 @06:17AM (#24479620)
Of course. For example, everyone knows that Alexander Nikolayevich Lodygin invented and applied for the patent on carbon-filament bulb in 1872, was granted it in 1874 and in that same year founded Electric Lighting Company. Then there were some Tzarist repressions, he emigrated in the US, patented tungsten filament in 1893 (US Patent No. 575,002), sold it to GE, returned to Russia in 1907, in 1917 emigrated to the US again, and died in 1923 in Brooklyn, New York.

Not to mention his other works on other things electrical: motors, welding, ovens and smelting.
