Before braille existed, there were books for blind readers, but many used raised versions of printed letters. These shapes were slow to read by touch, and students could not easily write them by hand.
Louis Braille lost his sight after a childhood accident and studied at a school for blind students in Paris. There he learned about “night writing,” a code created for soldiers to share information silently in the dark. It used twelve dots and was too complicated to read quickly with a finger.
Between the ages of thirteen and sixteen, Braille improved the idea. He created a small cell with only six dots. Different combinations could represent letters, numbers, and punctuation. The system was later used for music and mathematics too. Instead of copying shapes designed for the eye, it was designed for the fingertip.
Braille’s system was not officially recognized during his lifetime. France adopted it in 1854, two years after his death. It later spread around the world. Today, braille is used not only in paper books but also on electronic displays that raise and lower tiny pins. The technology has changed, but the basic six-dot cell remains powerful because it lets people both read and write through touch.
