The history of National Fire Prevention Week has its roots in the Great Chicago Fire, which occurred on October 9, 1871. This tragic conflagration killed some 300 people, left 100,000 homeless, and destroyed more than 17,000 structures. The origin of the fire has generated speculation since its occurrence, with fact and fiction becoming blurred over the years. One popular legend has it that Mrs. Catherine O'Leary was milking her cow when the animal kicked over a lamp, setting the O'Leary's barn on fire and starting the spectacular blaze. However the massive fire began, it swiftly took its toll, burning more than 2000 acres in 27 hours. The City of Chicago quickly rebuilt, however, and within a couple of years residents began celebrating their successful restoration by memorializing the anniversary of the fire with festivities. 

Intending to observe the fire's anniversary with a more serious commemoration, the Fire Marshals Association of North America (FMANA), the oldest membership section of the National Fire Protection Association (NFPA), decided that the 40th anniversary of the Great Chicago Fire should be observed not with festivities, but in a way that would keep the public informed about the importance of fire prevention. So on October 9, 1911, FMANA sponsored the first National Fire Prevention Day. 

In 1920, President Woodrow Wilson issued the first national Fire Prevention Day proclamation. For more than 70 years, the nonprofit NFPA has officially sponsored and selected the theme for the national commemoration of Fire Prevention Week, honoring the anniversary of the Great Chicago Fire and using the event to increase awareness of the dangers of fire. And every year since 1925, the President of the United States has signed a proclamation pronouncing the Sunday-through-Saturday period in which October 9 falls a national observance. 

When President Calvin Coolidge proclaimed the first National Fire Prevention Week, October 4-10, 1925, he noted that in the previous year some 15,000 lives were lost to fire in the United States. Calling the loss "startling," President Coolidge's proclamation stated, "This waste results from conditions which justify a sense of shame and horror; for the greater part of it could and ought to be prevented... It is highly desirable that every effort be made to reform the conditions which have made possible so vast a destruction of the national wealth." 

NFPA continues today to make National Fire Prevention Week a priority and counts on the participation and effort of tens of thousands of fire and safety professionals, American Red Cross volunteers, and individuals working to reduce the risk of fire and the toll its takes on our society.
