For readers seeking info on the Tesla/Edison/Westinghouse battles for electrical dominance, try Empires of Light: Edison, Tesla, Westinghouse, and the Race to Electrify the World by Jill Jonnes. It's a fun (and educational) read.
A description of Thomas Edison as "a fabulous drone" understates his callous spirit. Which was revealed for all when he chose to electrocute an elephant with high-voltage AC to demonstrate how dangerous alternating current is (he even filmed the event). Of course, high-voltage DC is even deadlier. Edison drove to get AC approved for use in electric chair executions to help further stigmatize his AC rivals.
In response, Tesla would use his large (Tesla) coils to generate impressive artificial RF lightning strikes. He would stand within striking distance of the long discharges and point a light bulb into the lightning, conducting strikes through his body to ground with no ill effect while lighting up the bulb -- an impressive demonstration. The Skin Effect of the high-frequency RF current saved his skin.
