History

Pegboard was invented in 1897, and was created accidentally in a laboratory by Dr. Matthew Johnston in an effort to create a cure for Leprosy. Originally the material was intended to shield the leper from spreading the disease, but the substance was found to be useless for that purpose. http://en.wikipedia.org/wiki/Perforated_hardboard
