Henry Parmelee created the fire sprinkler in 1864 to protect his piano factory. Parmelee patented his idea and had great success with it in the U.S. He then traveled to Europe to show people that there was finally a way to help stop a building fire before everything was destroyed.

His invention did not get as much attention as he had planned. Most people could not afford to install a sprinkler system. Once Parmelee realized this, he turned his efforts on educating the insurance companies about his system. He talked about how the sprinkler system would reduce the loss ratio, thus saving money for the insurance companies. He knew that he could never succeed in obtaining contracts from the business owners to install his system unless he could at the same time ensure for them a reasonable return in the shape of reduced premiums.

In this connection he was fortunate enough to enlist the sympathies of two men, who both had connections in the insurance industry. The first of these was Major Hesketh, who, in addition to being a cotton spinner in a large business in Bolton, was Chairman of the Bolton Cotton Trades Mutual Insurance Company. The Directors of this Company and more particularly its Secretary, the late Peter Kevan, took an interest in Parmelee
