The city of Chicago has been known by many nicknames, but it is most widely recognized as the "Windy City".
The earliest known reference to the "Windy City" was actually to Green Bay in 1856.The first known repeated effort to label Chicago with this nickname is from 1876 and involves Chicago's rivalry with Cincinnati. The term "Windy City" came into common usage when it was popularized by New York City editor, Charles Dana, in The Sun during the bidding for the 1893 Columbian Exposition. Chicago won the Exposition, which did not please Dana. The popularity of the nickname has endured, long after the Cincinnati rivalry and the Columbian Exposition ended.
