The World's Columbian Exposition (also known as the Chicago World's Fair) opened to the public on May 1st 1893. Its largest attraction however, opened on this day in 1893. The Ferris Wheel, named after its inventor George Washington Gale Ferris, Jr., was intended to rival the 1889 Paris Exposition's Eiffel Tower. The structure which boasted 60 passenger cars, had a total capacity of 2,160 and had around 38,000 riders per day. Although the original wheel was demolished in 1906, you can read about Ferris Wheels and the Chicago World's Fair at your Milwaukee Public Library.
