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). "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 discovered a year ago [...] If I 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.
