In the final decades of the 19th century, three brilliant and visionary titans of America's Gilded Age - Thomas Edison, Nikola Tesla, and George Westinghouse - battled as each vied to create a vast and powerful electrical empire. In Empires of Light, historian Jill Jonnes portrays this extraordinary trio and their riveting and ruthless world of cutting-edge science, invention, intrigue, money, death, and hard-eyed Wall Street millionaires. At the heart of the story are Thomas Alva Edison, the nation's most famous and folksy inventor, creator of the incandescent light bulb and mastermind of the world's first direct current electrical light networks; the Serbian wizard of invention Nikola Tesla, an eccentric dreamer who revolutionized the generation and delivery of electricity; and the charismatic George Westinghouse, Pittsburgh inventor and corporate entrepreneur, an industrial idealist who in the era of gaslight imagined a world powered by cheap and plentiful electricity and worked heart and soul to create it. Empires of Light is the gripping history of electricity, the "mysterious fluid", and how the fateful collision of Edison, Tesla, and Westinghouse left the world utterly transformed.
