History
The warded lock is one of the most ancient lock designs still in modern use. During the Middle Ages they were used prolifically on monasteries where, because money and time were not issues, their complexity grew. All had the same inherent problem: by removing most parts of the key, except the bare minimum to operate the bolt, and so producing a skeleton key, the wards could be bypassed.

Famous quotes containing the word history:
“No one can understand Paris and its history who does not understand that its fierceness is the balance and justification of its frivolity. It is called a city of pleasure; but it may also very specially be called a city of pain. The crown of roses is also a crown of thorns. Its people are too prone to hurt others, but quite ready also to hurt themselves. They are martyrs for religion, they are martyrs for irreligion; they are even martyrs for immorality.”
—Gilbert Keith Chesterton (1874–1936)
“It is remarkable how closely the history of the apple tree is connected with that of man.”
—Henry David Thoreau (1817–1862)
“Like their personal lives, women’s history is fragmented, interrupted; a shadow history of human beings whose existence has been shaped by the efforts and the demands of others.”
—Elizabeth Janeway (b. 1913)
