From Chicago to Shanghai, 138 Visionary Years of World's Fairs

From Chicago to Shanghai, 138 Visionary Years of World's Fairs: "The World's Columbian Exposition, or the Chicago World's Fair, commemorated the 400-year anniversary of Christopher Columbus' arrival in the Americas. Between May and October of 1893, Jackson Park became the White City, at once a carnival and an enchanting courtyard modeled on classical architecture. Since electric lights were a new development, power companies competed for the opportunity to light up the fairgrounds while showcasing their technology. Although General Electric (supported by Thomas Edison and J.P. Morgan) put up a good fight, Westinghouse Electric outbid them with an offer to power up the fair using Nikola Tesla's alternating current technology."
