I wanna start this blog with a post about a prominent Ukranian inventor, Fedor Pyrotsky. This little lad originates in Ukraine, which was a region of the Russian Empire. That was time to get education, the boy went to the capital of the St. Petersburg. Upon the arrival back home, Pyrotsky encountered another impressive scientist of the period, Pavel Nikolayevich Yablochkov. The scientist is famous for the creation of the most of the the first known incandescent lamps. When Pyrotsky returned in Petersburg one more time, person proposed a number of improvements in blast. However the principal theme of his life was trains. In 1875, person made about a mile of railroad vehicles driven by electricity. In 5 years, Fedor rebuilt a number of old trams driven by horses in the city to electric current, which triggered fury of the owners of traditional transport. It's pity that, the Pyrotsky can not get a sponsor f
or the development and the work had to be rolled off shortly. Karl Siemens, one of the constitutor of Siemens corporation, impressed by Fedor's work, made a tram line powered by electricity in Germany.
After his fail with the transportation Fedor endured working in electrical engineering, and laid the first known subterranean cable in Petersburg, and also became the most of the developers of the underground city electric network. Fedor Apollonovich expired in want, so it was necessary to poverty scientist's things to bury him. Source.
