Alexander Nikolayevich Lodygin ((ロシア語:Александр Николаевич Лодыгин); October 18, 1847 – March 16, 1923) was a Russian electrical engineer and inventor, one of inventors of the incandescent light bulb. Alexander Nikolayevich Lodygin was born in Stenshino village, Tambov Governorate, Russian Empire. His parents were of a very old and noble family (descendants of Andrei Kobyla like Romanovs), but of very moderate means. He studied at the Tambov Cadet School (1859–1865). Then he served in the ''71st Belev regiment'', and in 1866–1868 studied at the Moscow Infantry School. Soon after graduation from his military school he retired from the military and worked as a worker at the Tula weapons factory. ==Timeline== *1872: He decided to go to Saint Petersburg to attend lectures at Saint Petersburg Institute of Technology and to start working on an ''electrical helicopter'' (''electrolyot''). The electrical helicopter would need some sort of artificial lighting that would have to be electrical. He decided to start his helicopter work by developing a source of electrical light for it. *1872: He applied for a Russian patent for his filament lamp. He also patented this invention in Austria, Britain, France, and Belgium. For a filament, Lodygin used a very thin carbon rod, placed under a bell-glass. *August 1873: He demonstrated prototypes of his electric filament lamp in the physics lecture hall of the Saint Petersburg Institute of Technology. *1873–1874: He conducted experiments with electric lighting on ships, city streets, etc. *July 11, 1874: He was granted the Russian patent, as patent number 1619. *In 1874, the Petersburg Academy of Sciences awarded him with a Lomonosov Prize for his invention of the filament lamp. That same year, Lodygin established the Electric Lighting Company, A.N. Lodygin and Co. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Alexander Lodygin」の詳細全文を読む スポンサード リンク
