 in Chicago 1893

- The great victory of Tesla/Westinghouse's Polyphase alternating current system electricity.

By Dr. Ljubo Vujovic and Marko Vujovic

The World Columbian Exposition was the World's Fair commemorating 400 years since Christopher Columbus set foot in the New World.  Located on Lake Michigan to facilitate access by sea, road and rail.  It was a gathering of ideas, men and technologies from every quarter of the globe, with each country contributing its best of their industrial, cultural, commercial and educational enterprises.  The Renaissance style of the exposition buildings was unsurpassed by its architecture beauty.  The Exposition itself was a work of art.  The Exposition was a brilliant spectacle of science, art and industry.  All the world has its pilgrimage to Columbian Exposition in 1893.  Westinghouse became dedicated to promoting the polyphase alternating current system and felt that his best chance to introduce it to the public at large would be at the 1893 World's Columbian Exposition in Chicago.  The exposition was the greatest event in America and in the world at that time.  Ever the ingenious promoter Westinghouse outbid Edison for the contract to power the expositions lighting and electrical systems.  Over Two Hundred thousand electric light bulbs were illuminated by Tesla's polyphase alternating current system.  The Westinghouse display was a historic collection of machines, all powered with Tesla/Westinghouse alternating current.  It was a spectacular display of lights and energy, which illuminated the exposition.
