*Ø* Tesla: almost-forgotten genius

July 9, 1856 Nikola Tesla (d. January 7, 1943), the Croatian-born American electrical engineer, inventor of the alternating current (AC) motor, was born on this day at Smiljan, Lika. He was a great genius whose luck was not as great as his abilities, and for many years his name was almost completely lost to public knowledge.

The unit of magnetic flux in the metric system is the 'tesla', as another unit is the 'faraday'. His Tesla Coil supplies the high voltage for the computer monitor you are looking at. The electricity for your computer comes from a Tesla design AC generator, is sent through a Tesla transformer, and gets to your house through 3-phase Tesla power. The electric power of Niagara was harnessed through his inventions.

During Tesla's lifetime, the US Patent Office recorded 111 utility patents, one reissued patent, two utility patent corrections and one utility patent disclaimer. US patent number 613,809 described the first device anywhere for wireless remote control. "You do not see there a wireless torpedo," he angrily corrected a newspaper reporter, "you see there the first of a race of robots, mechanical men which will do the laborious work of the human race."

"When wireless is fully applied the earth will be converted into a huge brain, capable of response in every one of its parts," Tesla told Morgan. Tesla's plan for an international wireless communications system was funded for a time by the squillionaire, JP Morgan, but Morgan prematurely lost faith in the inventor and pulled the plug on the money bin – perhaps one of the worst financial decisions of the 20th century. Tesla had to abandon his ambitious project forever. The newspapers called it, "Tesla’s million dollar folly." Humiliated and defeated, Tesla suffered a nervous breakdown.

By 1890 Nikola Tesla was generating fields that would light up, without any wires, phosphorescent tubes across his laboratory. Yet for all this, his name was forgotten for decades, until recently when at long last the public has come to know of one of history’s great geniuses ...
