How a fifteen-year-old redesigned reading

The story usually told, including on this page until recently

The usual account opens on a battlefield: an old artillery captain called Charles Barbier invented a code for soldiers to read at night, came to the school for the blind in Paris to demonstrate it, and a blind boy improved it. Philippa Campsie, who went back to Barbier’s own letters and publications, calls that story “almost wholly fiction”. This page told a version of it too. What follows is what the sources named at the foot of the page support.

Barbier was not a soldier when he invented it

Charles Barbier de la Serre entered the French artillery in 1784 and resigned his commission in May 1792, two days after being made captain. He went to the United States that year. When he came back to France is not known, and he did not rejoin the military.

His Essai sur divers procédés d’expéditive française appeared in 1815, twenty-three years after he left the army. It argues that ordinary writing takes more time to learn than “country people and city artisans” have. Campsie’s reading of his papers is that he meant his methods for people who could not see, for people who were deaf, and for people with no schooling, not for the army.

It was a grid, and he never called it sonography

The word “sonography” is often attached to Barbier’s method. Later writers used it; Barbier himself never did.

His book of 1815 rests on a grid: the letters of the alphabet in five rows of five, each written as a row number and a column number. W is missing, because it was not a regular part of the French alphabet at the time. There was a second grid for sounds, and the method existed in both versions, one phonetic and one using ordinary spelling.

How it reached the school

Barbier sent his method to the Institution Royale des Jeunes Aveugles in Paris, and its director, Sébastien Guillié, rejected it. The school taught reading from raised type, and Guillié had invested heavily in raised-type books.

In 1821 Guillié was replaced by Alexandre-René Pignier, and Barbier wrote again. Pignier had someone at the school learn the method and demonstrate it, first to the board and then to the pupils. Barbier did not demonstrate it himself, and it was not used at the school in its phonetic version. With it the pupils could take notes and read them back, which raised type had not let them do.

Halving the cell

Louis Braille was born in Coupvray on 4 January 1809. At the age of three he was blinded in an accident with a tool in his father’s harness shop; sympathetic ophthalmia and total blindness followed. He entered the school in Paris in 1819.

In 1824, at fifteen, he took Barbier’s system as his starting point and cut its twelve-dot cell in half. He wrote with the tools Barbier had invented. Barbier and Braille did not meet until 1833, after Braille had published.

The dashes he removed

The system was first published in 1829, and that version is not the braille in use today: it had dots and dashes. Perkins School for the Blind, which holds a copy of the book, records that Braille dropped the dashes in the second edition because they were hard to tell from dots by touch. A fuller account of the system appeared in 1837.

The school banned it for four years

When Pierre-Armand Dufau replaced Pignier as director in 1840, the use of Braille’s system at the school was banned. Braille kept the support of friends and colleagues, and its official use was restored in 1844 through the deputy director, Joseph Guadet.

In the last years of his life Braille was ill with tuberculosis. He died in Paris on 6 January 1852, two days after his forty-third birthday.

Adopted after his death

Britannica’s account is that the system “was immediately accepted and used by his fellow students, but wider acceptance was slow in coming”. The school in Paris did not adopt it officially until 1854, two years after Braille died. A century after his death his remains were moved to the Panthéon.

What the French origin left in the alphabet

Braille designed the code for French, and the structure still shows it. The first ten letters use only the top four dots; the next ten add dot 3; the next add dots 3 and 6. The letter w does not fit: it is dots 2-4-5-6, in the group formed by adding dot 6. W was not a regular part of the French alphabet at the time, and Barbier’s grid of 1815 had left it out as well.

Standardisation took another century and a half

A single braille code for the English-speaking world was not agreed until 1932, when agencies for the blind in Great Britain and the United States met in London and settled on Standard English Braille. Unified English Braille, the standard this site follows, was ratified by the International Council on English Braille in 2004 and has since been adopted in all of its member countries. That is recent enough that older reference material may not match, and recent enough that the tables software ships are still catching up. The braille guides carry on from here.
