Safety matches were invented by Johan Edvard Lundstrom of Sweden in 1855. Lundstrom's new match was the first simple and safe way to make a fire. His new safety match could only be lit by striking the match against the specially-prepared surface that came attached to the box. Lundstrom put red phosphorus on the rough striking paper (on the outside the match box); the other fire-starting chemicals were on the match's head. Previous matches gave long-time users an ailment called "phossy jaw;" this was a painful and deadly disease caused by the older matchs' yellow phosphorus that ate into the users' jaws.
