Louis Braille, a French young blind student, invented the braille code in the early 19th century.

The Braille alphabet largely follows the French alphabetical order. It is based on a logical construction by series of ten characters.

• First series: the first ten letters (A to J) are made up only of combinations using the four dots at the top of the cell.
• Second series: the next ten letters (K to T) are composed of the same combinations as the first series, to which dot 3 has been added. Thus, to write letter L (dots 1, 2, 3), the two dots used in the cell for letter B (points 1, 2) have been retained, with the addition of dot 3.
• Third series: the next five letters (U to Z) are composed of the same combinations as the second series, to which dot 6 has been added. Thus, letter V has the dots 1, 2, 3 of letter L, and dot 6.

Only W (dots 2, 4, 5, 6) escapes this rule. Indeed, at the time of the invention of the braille code, this letter was not useful to write French words. It therefore had to be added later.
