Theodore Talk -- When the World Came to Chicago: The World's Columbian Exposition of 1893

Virtual meeting

No group assigned

In this lavishly illustrated talk, Dr. Nicholas McCormack will examine a brief history of world's fairs and the context for Chicago playing host to the first one in the United States. You'll learn how the fair was designed, what its intended purpose was, and its impact on Chicago and the future of world's fairs, especially Chicago's second world's fair in 1933-34. There is a vibrant scholarship — a historiography — of world's fairs that highlights serious issues such as colonialism, classism, and racism, which many popular tellings of the Columbian Exposition and other world's fairs either ignore or distort. This talk will engage with those debates and issues as well.

Ends

Theodore Talk -- How Corn Changed Itself and Then Changed Everything Else: The Role Agriculture Played in the Early Days of Chicago

Virtual meeting

No group assigned

Thanks to corn, the Midwest was settled faster than any other region in history, and Chicago became immensely influential. From the Chicago Stock Yards to the Chicago Board of Trade, the city changed the way the world did business. However, vampires, whiskey, Henry Ford, time zones, Fritos, and the Chicago Bears are also part of this remarkable story. Cynthia Clampitt, author of Midwest Maize: How Corn Shaped the U.S. Heartland, will present what may prove to be the corniest Theodore Talk ever!
