Locksmiths are people who design and make locks and other protective machines for buildings objects cabinets and others. This art has evolved over time with the developing technology. Locksmiths history dates back to ancient Babylon and Egypt over 4000 years ago.
Locks made in those many years ago were made of wood pins which could prevent moving bars. Wooden keys which were large were also used and made to move the pins in the locks. One of the oldest locks was found in Nineveh an ancient Egypt city which used crossbars with movable pins that dropped into the holes on the crossbar stopping their movement. The key inserted moved the pins in the crossbars to allow movement of the crossbars. The Greeks also used wooden locks.
Metal locks were first used by the Roman Empire due to its vast wealth and were designed using the Egyptian technology. The metal locks were stronger than the wooden locks and had the advantage of more improved ward locks which is the key hole having projections.
This made it possible for only specific key to be used for a specific lock unlike other earlier locks which could be opened by any key. As the Roman Empire flourished in its economy and wealth there was an increasing demand in locks and keys which led to more numbers of locksmiths. The locksmiths majored in designs and aesthetics of the locks with less improvement in the technology of the locks. By the 14th century locksmiths had spread across the major cities.
In the 18th century bonuses were given to locksmiths who could invent more secure and newer locks and this influenced the growth of the industry with some locksmiths even going to form companies and during this time Jeremiah Chubb invented the lock that could not be picked by any other key.
This lock was invented since all locks had leaked their mode of opening them and fake keys could be made and open the locks In Portsmouth Dockyard there was a breaking using keys by thieves that led into the British government invoking a competition for locksmiths to develop a lock that could be opened only by its unique key.
It was during this time that Jeremiah invented a lock that could detect the key and incase of a wrong key it would malfunction hence it could be opened by a unique key to open it. This invention worn him 100 pounds prize and he emerged as a lock brand name up to today.
Yale is the other prominent brand that emerged in the 19th century. Linus Yale junior came up with a cylinder lock which is still in use today in Europe and America. This cylinder lock is an improved design of the Egyptian lock smiths.
With the introduction of industries leading to mass production the locksmiths have now moved into a repair person work or duplicating keys for those in need of extra keys. In the current world they work in shop or intelligence bodies.
