What did I learn today – Fire hydrant irony

A quick one today. Nobody can verify who invented the fire hydrant, because the patent was destroyed in a fire…

The invention of a post- or pillar-type fire hydrant is generally credited to Frederick Graff Sr., Chief Engineer of the Philadelphia Water Works around the year 1801. It had a combination hose/faucet outlet and was of “wet barrel” design with the valve in the top. It is said that Graff held the first patent for a fire hydrant, but this cannot be verified because the patent office in Washington D.C. caught on fire in 1836 destroying many patent records from that period in the process.[3]
