Locksmithing is an art, as well as a science. The history of locks goes back to Ancient Egypt and Babylon, approximately 4000 years ago, when wooden devices used a tin tumbler principle to prevent free movement of a door bar. After the adoption of advanced metallurgy in 18th century Europe, locksmiths were finally able to create much more durable locks and keys. The development of the lock industry in America was led by men of genius who developed their own machinery to produce better locks, at lower costs, than those imported from other countries. Although the introduction of electronic locking systems revolutionized the industry once again, there is still high demand for the technical skills, locksmith experience, and industry knowledge found at Anderson Lock.
