Every letter, A to Z.

Where it comes from

Louis Braille, blind from the age of three, published his system in 1829 when he was twenty. He built it from a soldier's night-writing code and cut it down to a cell of six dots that a fingertip reads in one touch.

A message worth knowing: Six dots. Every Braille letter fits in a cell of two columns of three dots, small enough to read in one touch.
