Henry S. Parmalee

From Wikipedia, the free encyclopedia

Henry S. Parmalee, a piano maker from New Haven, Connecticut, invented a fire sprinkler system in 1874 to protect his piano factory. While other patents for fire sprinklers predated Parmalee's work, he is credited with the first practical automated sprinkler head.

His piano company The Mathushek Piano Manufacturing Co, is credited as being the first building in the United States to be equipped with a fire suppresion system (automated sprinkler system).
