06/21/1893 - The Ferris Wheel was introduced at the World's Columbian Exposition in Chicago, IL.. With a height of 80.4 metres (264 ft) it was the largest attraction at the World's Columbian Exposition in Chicago, Illinois.
The World's Fair: Columbian Exposition, was a World's Fair held in Chicago in 1893 to celebrate the 400th anniversary of Christopher Columbus's arrival in the New World in 1492. I just finished reading a book about this (The Devil In the White City, by Erik Larson), so I'm frolicing in seeing more photos of the Fair right now.
Chicago's World's Fair of 1893 not only captured the imagination and ingenuity of the elite, but also captured that of one of America's first known serial killers H.H. Holmes. For the overflow of event travelers, he build a hotel that was constructed soley for the the purpose of confusion, torture and death.
