The condition has long been recognized. A 5000-year-old pre-Columbian mummy discovered in the Chilean mountains offers the earliest documented evidence of frostbite. More recently, Napoleon's surgeon general, Baron Dominique Larrey, provided the first description of the mechanisms of frostbite in 1812, during his army's retreat from Moscow. He also noted the harmful effects of the freeze-thaw-freeze cycle endured by soldiers who would warm their frozen hands and feet over the campfire at night only to refreeze those same parts by the next morning.
Although frostbite used to be a military problem, it is now a civilian one as well. The nose, cheeks, ...
