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