Louis Braille's original publication, Procedure for Writing Words, Music, and Plainsong in Dots (1829), credits Barbier's night writing as being the basis for the braille script. It differed in a fundamental way from modern braille: It contained nine decades (series) of characters rather than the modern five, utilizing dashes as well as dots. Braille recognized, however, that the dashes were problematic, being difficult to distinguish from the dots in practice, and those characters were abandoned in the second edition of the book.

Louis Braille was a French educator and the inventor of a reading and writing system named after him, braille, intended for use by visually impaired people. His system is used worldwide and remains virtually unchanged to this day.
