The lock

Man invented keys and locks to protect home and property. Simple locks and keys made of wood were used in Egypt 4000 years ago. Swedish inventor Christopher Polhem designed a padlock in the beginning of the 1700s, which was manufactured until the 1950s.

For as long as people designed locks, people have tried to crack them. In 1784 the Englishman, Joseph Bramah, invented a lock and offered a large sum of money to anyone who could open it without a key. After 67 years the lockmaker Hobbs managed to do it in the end, who himself invented a complicated lock for banks.

Modern locks are electronic and are opened with a code or key card. There are even locks with electronic fingerprint readers and locks which scan the iris of the human eye.
