What did Louis Braille invent?

Louis Braille invented a writing system for blind people, now known as braille. It uses raised dots that readers feel with their fingertips to represent letters, numbers, punctuation, and even musical notation.

Braille was born in France in 1809 and lost his sight after an accident in his father’s workshop when he was a child. As a student at the Royal Institute for Blind Youth in Paris, he encountered a military “night writing” code developed by Charles Barbier. Braille simplified that idea into a compact six-dot cell, allowing many more symbols to fit beneath a fingertip.

He published an early version of his system in 1829 and refined it during the following years. The code was not immediately accepted by every teacher, but it eventually became a major route to literacy and independence for blind and visually impaired people worldwide. A common mix-up is crediting Braille with inventing only a reading code: his system supports writing as well as reading.
