In 1873, in the city of St. Petersburg in Russia, the world's first city electric lights were lit. The father of the incandescent lamp was electrical engineer Alexander Ladygin. His workshop was just on the street where the first lanterns appeared.

Soon the electrification relay was intercepted by the equally talented inventor Pavel Yablochkov. Electric candles invented by him in the eighties of the 19th century have already illuminated the main street of St. Petersburg - Nevsky Prospekt, as well as the streets and houses of Paris, Rome, San Francisco, Rio de Janeiro and Mexico City.

Newspapers all over the world wrote that "light comes from Russia" and "Russia is the birthplace of electricity."
But at that time in America, the successful inventor Thomas Edison bought a patent for his incandescent lamp with a tungsten filament from the impoverished Russian emigrant Alexander Ladygin and modified a convenient base and cartridge, and went down in history as the creator of the first commercially successful incandescent lamp.

The phrase "commercially successful", alas, is often forgotten.
