The Evolution of Night Writing to Braille

During the Napoleonic Wars, Captain Charles Barbier invented 'night writing' to send messages without revealing positions. Although the military ignored it, Barbier introduced it to the Royal Institute for Blind Youth in Paris. Louis Braille, a student there, refined the system into a six-dot cell alphabet, which became the universal writing system for the blind, now used in over 130 languages.
