The fire hydrant, as a concept, does not have a single inventor, as it evolved over time. However, one of the early inventors associated with the modern fire hydrant is Frederick Graff Sr., who is credited with designing an early version of the fire hydrant system in Philadelphia in the early 19th century.

The claim that the patent for the fire hydrant was lost in a fire likely stems from the fact that the U.S. Patent Office building burned down in 1836, destroying many early patent records. This included countless patents issued before the fire, making it impossible to confirm who held the original patent for the fire hydrant.

So, while we attribute much of the early design to Graff, the anecdote about the patent being "lost in a fire" adds an ironic twist to the history of fire hydrants!
