The Fact
The origin of the word “locksmith” is incredibly murky. Although many sources have guessed or proposed to offer a derivation, the truth is that there is no consensus. Without consensus, therefore, we must infer that nobody knows for sure.

A Little History

The earliest known form of lock appears as a simple door slide or draw bar, usually positioned on the inside of a door and moved into a hole in the surrounding frame or structure. The Chinese may have offered the next advance in locks with the tumbler lock.

After the tumbler lock, we see an evolution of the invention with the Etruscans and the warded lock. The Roman locks were of this design also. This type of lock introduces the idea of a spring or some other component that, when used with the key, provides a feeling similar to that of a tumbler (but does nothing to increase the security of the device.) In about 1650 a fourth kind of lock appeared. Invented by M. Regnier, a director at the Mas√©e d’Artillerie at Paris.
