Jonas Wenström

Jonas Wenström (born August 4, 1855 in Hällefors, died December 22, 1893 in Västerås) was a Swedish engineer and inventor. He invented in Sweden the three-phase electric power system, the basis for ASEA (later ABB).[1] "It goes to conspiratorially speculate whether Edison got his idea from the Swedish pen pal. Wenström writes: "Edison's new invention of electric light: a glowing carbon strip, is the same thing that I found on a year ago [...] If had his laboratory, and resources, I would have done the same and better [. ..] a graphite strip between two mica plates provide a more effective light than Edison's.
