death Pavel Yablochkov Died 31 Mar 1894 at age 46 (born 14 Sep 1847). Pavel Nikolayevich Yablochkov (also called Paul Jablochkov) was a Russian electrical engineer who invented an improved arc lamp, known as the Yablochkov candle (1876). Being cheap and relatively inexpensive, it was used in public buildings and to light streets for several decades before the advent of incandescent lighting which required much less maintenance. A brilliant white light was produced by an electric arc between two parallel carbon rods, using alternating current to ensure that the rods vaporised at equal rates. Yablochkov candles were used from 1877 in Paris, and were installed in London along Victoria Embankment (1878), followed by Billingsgate fish market, the Mansion House and Holborn Viaduct. |
