In 1892 George Westinghouse won the contract to power the Columbian Exposition. The Westinghouse company, with Tesla's guidance, built a power system for the exposition that produced three times more energy than was being utilized by the entire remainder of Chicago. Tesla had a large display including phosphorescent lighting (a precursor to fluorescent lamps) powered without wires by high-frequency fields and the Egg of Columbus. The success of the Tesla Polyphase System installed at the exposition ensured Westinghouse would be selected to harness Niagara.
