Great Chicago Fire
"National Fire Prevention Week has its roots in the Great Chicago Fire of October 9, 1871. This quick-spreading fire killed 300 people, left 100,000 homeless, and destroyed more than 17,000 buildings. How did it start? One popular legend tells the story of Mrs. Catherine O’Leary milking her cow when the animal kicked over a lamp, setting the O’Leary’s barn on fire. The blaze burned more than 2000 acres in twenty-seven hours. The City of Chicago rebuilt quickly, and within a couple of years residents began celebrating their successful restoration by memorializing the anniversary of the fire."
