Aubin was a very clever and talented locksmith working from the end of the Georgian period through to the mid-Victorian period.

He had a very high sence of pride in his workmanship, which amongst other factors eventually led to the failure of the company. However Aubinís influence on the lock trade is considerable and can still be seen in products today.

The reliability of springing could be considered essential as far as locking devices are concerned. Aubin was noted as having perfecting the technique of integral lever springs, which had hitherto been of both steel and separate construction. It was to be much later technologies that allowed for reliable steel springing.

Until all levers were aligned any attempt at withdrawing the bolt would cause the anti-pressure device to come into play. One additional feature that Aubin incorporated in his 'A1' locks was a dead lift lever. Any attempt at manipulating the lock would almost certainly lift this lever and allowing the anti-pressure device to come into play.
