  • In a Moment of Vision...

  • Early 1800s.

  • It's the middle of the Napoleonic Wars in the middle of Europe,

  • and it's the middle of the night.

  • One Captain Charles Barbier of Napoleon's army

  • is trying to relay a message to one of his troops.

  • But sending written communications to the front lines

  • can be deadly for the recipient.

  • Lighting a candle to read the missive can give away their positions to the enemy.

  • In a moment of vision,

  • Barbier pokes a series of holes into a sheet of a paper with his blade,

  • creating a coded message that can be deciphered by fingertip,

  • even in the pitch black.

  • The merits of his so-called night writing are never acknowledged by the military,

  • but in 1821, Barbier approaches the Royal Institute for Blind Youth in Paris

  • in the hopes that they might find a use

  • for his innovative, new communication method.

  • There, a precocious teen by the name of Louis Braille does just that.

  • Louis spends the next several years improving on Barbier's idea,

  • creating an organized alphabet fitting into a six dot standardized cell.

  • The system catches on.

  • Today, Braille is the universally accepted system of writing for the blind,

  • adapted for more than 130 languages.
