Before there was braille, books for the blind consisted of large 3-D letters. The books were very heavy and expensive. Louis got the idea for dots by hearing about the code the French army was using to deliver messages at night. The code was made up with dots and dashes which Louis simplified to dots. And then voila! A more sufficient way to make books for the blind.
