The fifth through ninth used dashes as well as dots, but proved to be impractical and were soon abandoned. The dash occupying the top row of the original sixth decade was simply dropped, producing the modern fifth decade. Assignment[ edit ] Historically, there have been three principles in assigning the values of a linear script print to Braille: Under international consensus, most braille alphabets follow the French sorting order for the 26 letters of the basic Latin alphabetand there have been attempts at unifying the letters beyond these 26 see international braillethough differences remain, for example in German Braille and the contractions of English Braille.
Barbier was an artillery captain in the French Army who had devised a system for soldiers to communicate at night without a sound. His system combined 12 dots to represent sounds and he called it sonography.
It is also referred to as "night writing. Both students and teachers at the Institute were intrigued by the promise of sonography, and, despite the difficulty of the system, sonography was introduced in the school as an auxiliary teaching method.
Louis and his classmates soon identified one of the chief flaws of Barbier's system in addition to its complexity: Louis determined to take Barbier's system and improve upon it.
Between the ages of 13 and 16 Louis worked on perfecting an embossed dot system. Like Barbier's, Louis' system used raised dots, but beyond that similarity Louis' ideas were his own. For three years Louis spent his free time refining his code.
On the weekends, evenings, and summer vacations in Coupvray, Louis could be found with paper, slate, and stylus diligently working. When at age 15 he felt he had an adequate code, he shared it with Dr. Pignier, who had become his mentor.
Louis' system, based on a six-dot cell, was both simple and elegant.
A full braille cell consists of six raised dots arranged in two parallel rows, each having three dots. Sixty-four combinations are possible using one or more of these six dots.
A single cell can be used to represent an alphabet letter, number, punctuation mark, or even a whole word. Pignier encouraged the students at the Institute to use Louis' code. With it, they were able to achieve a level of literacy previously unavailable to them.Creator of night writing.

A soldier in Napoleon’s army, Barbier developed a system in that used 12 dots with a five line musical staff (Kersten, )/5(18).
Braille was based on a tactile military code called night writing, developed by Charles Barbier in response to Napoleon's demand for a means for soldiers to communicate silently at night and without a light source.
In Barbier's system, sets of 12 embossed dots encoded 36 different sounds. It proved to be too difficult for soldiers to recognize by touch and was rejected by the military.
Barbier’s night writing was deemed too difficult to use and was not further developed for use in warfare. Years later, however, in , the French Academy of Sciences recommended that Barbier use his concept to help teach the blind to read.
