Automatic fire suppression systems control and extinguish fires without human intervention. It was not until Feb. 10, 1863 that the first fire extinguisher patent was issued to Alanson Crane of Virginia. The first fire sprinkler system was patented by H.W. Pratt in 1872. But the first practical automatic sprinkler system was invented in 1874 by Henry S. Parmalee of New Haven, CT. He installed the system in a piano factory he owned.
