Tesla Lectures In Philadelphia
"On Light and Other High Frequency Phenomena" lecture is given before the Franklin Institute of Philadelphia.
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.
Westinghouse is awarded the initial Niagara Falls contract signifying the end of "The War of the Currents."
