“Topsy’s execution was a move on an oversized chessboard between two industrial behemoths. Edison’s invention of the light bulb had been only the first step in creating electricity generating stations and the network of wires which took that electricity into every American home to light up the bulbs produced en masse by his own factories. Without control of the generation and distribution of electricity, his bulbs would not have made him King of the Electron. Thus occurred the so-called War of the Currents against his great adversary, George Westinghouse.”
