Just a few wayward sparks is all it takes to burn down an entire city. That’s what happened in the Great Chicago Fire of 1871, one of the largest disasters in American history.
In popular accounts from the time, Catherine O’Leary’s cow kicked over a lantern in a humble barn on DeKoven Street. A few sparks became a small fire that quickly grew into an inferno that destroyed miles of homes and razed Chicago’s business district.
