Mona Lisa – an influential painting

This has nothing to do with smile though. For me, as Secretary of Homeland
Security, the Mona Lisa, or more specifically the theft of the painting in 1911,
made way to the mean of identifying people we use today: The fingerprinting
system. Its predecessor, Bertillonage, worked quite differently. In
Bertillonage, which was invented in the 19th century by the
Frenchman Alphonse Bertillon, several distinctive body features, like width of
head or length of right ear, were measured and catalogued. So when a criminal
was caught his body measurements were compared to those in the catalogue in the
hope of getting a match. This system contained a number of flaws, for example
were the measurements often inexact as every officer took them a lit bit
differently.
Critcs’ voices rose but it was the theft of
our lovely smiling lady that was the undoing of Bertillonage. As the theft had
caused a public uproar and one conspiracy theory chased the other the
government wanted the case resolved as soon as possible. Bertillon was
personally summoned to the crime scene and even managed to secure a
fingerprint. He and his colleagues engaged in seven months of comparing I with thousands
of data cards but found no match.
When the painting was finally regained two years later it turned out
that the thief had actually beenin Bertillone’s files all along. They just
could not find a match because it was the left thumbprint that was left on the
crime scene and the right one that was in the files. Needless to say, this
incident caused the police to rethink their tactics.
