Who Invented the Combination Lock?
The combination lock presents a puzzle to its opener — only one correct key or combination is able to open the lock’s unique design. These particular designs, however, have varied greatly throughout the last couple thousand years. Thus, the history of the combination lock is complicated and vague. With traces back to 704 B.C., improvements and modifications have culminated in the simple single- and multiple-dial locks ubiquitously found today.
