It’s now nearly 150 years since the Great Chicago Fire, which, according to popular legend, broke out after Catherine O’Leary’s infamous milking cow kicked over a lantern in the barn on the night of October 8, 1871. The resulting barn fire, aided by the wind, destroyed three square miles of the City of Chicago, killing approximately 300 people, destroying 18,000 buildings, and leaving 100,000 people – a third of the city’s population – homeless before it was finally brought under control the next day.
