Tesla, as Much a Wizard as Edison

It was left for a native of Serbia, of all out of the way, half barbaric countries, to give to mankind a genius who should make, next to Edison, the greatest advances of the nineteenth century in the adaptation of electricity to the needs of man. Nikola Tesla, the Serbian-American who devised the rapidly alternating current, is as much of a wizard as Edison. By the alternating current is meant, as Tesla expresses it, one that "jerks back and forth an inconceivable number of times to the second."
