The great inventor,
direct current promoted.
Tesla ticked him off.
This month Rob is challenging us to write Biography Haiku, I wrote this entry in part as a response to his entry Visionary.
The image of Thomas Edison was found at Wikipedia, and came from the Library of Congress archives.
Laith's Ramblings 
I hope he didn’t go to his grave pissed off at Telsa! 🙂
He’s likely pissed right now if he can somehow see this:
Nice.
Ha ha! I should have known someone would respond with Edison! Well played, Laith, and well-put. Who wouldn’t be ticked off by a competing technology that was superior and outpacing their own? It’s been a theory of mine that Edison wanted to try to profit from DC as much as possible before making the switch to AC, similar to how they do in other areas of manufacturing and technology today; but Tesla and Westinghouse must have had other ideas!
