By Pedro Zurita Louis Braille, who was born two hundred years ago, did not have the chance in his lifetime to witness the unbridled success of his simple but brilliant invention, a system which revolutionised the lives of blind people by opening the doors to knowledge and culture, fields which were hitherto out of bounds to them.
The birth pangs were not, however, insignificant. Braille completed his code in 1825, when he was barely 15 years old, but he passed away two years before France officially adopted his system in 1854. For decades his method faced rejection from both teachers at the Young Blind People’s Institute in Paris, where Braille himself studied and taught, and from sighted people. It was even banned for some time, and it was not until 1878 when an international congress held in Paris recognised the braille system, giving it the boost it needed to be implemented gradually worldwide. Since then training, development and independence for blind people have relied largely on this reading and writing system that is now, two hundred years after it was invented, used in practically every language in the world. Although in the past few years many have hailed the replacement of the braille system due to technological breakthroughs, no alternative method capable of substituting it completely has yet been developed. What is more, there are numerous signs that it enjoys rude health as it is used increasingly in everyday settings to enable blind people to become more independent. Braille is still irreplaceable in this respect, as we can see, for example, with the cosmetics firms, food companies and wine merchants who market their products with braille labeling, the European Union directive that makes it obligatory to have braille signage in new lifts, or the fact that since October 2005 all medicines in the European Union must carry braille labeling. Yet more initiatives can be found in the field of citizens’ rights. Countries such as France, Germany, Spain, India, Mexico, Colombia and Costa Rica are using braille to come up with different methods to ensure blind people are able to exercise their vote independently in elections. The logic of an alphabet The simple and logical structure of the braille system is based on the presence or absence of dots in a cell containing two parallel columns, each with three dots. The different permutations of dots in the six-dot cell give us 63 different combinations representing all the letters of the alphabet. Louis Braille based his system on the so-called "night writing" developed by Charles Barbier, a captain in the artillery, to enable the military to send messages in the dark. Braille learnt about this tactile code when he was just 10 years old and, after studying it, he reached the brilliant conclusion that the two columns containing six dots each put forward by Barbier should be reduced to two columns of three, an ideal size for the perception of a fingertip. Braille also showed that the sense of touch was significantly more sensitive to dots than to the linear system used in the code created some years previously by Valentin Haüy. Haüy’s system, which used lines to represent the letters of the visual alphabet, was the one Braille had learnt when he began at the Young Blind People’s Institute in Paris, founded by Haüy himself in 1784. Using this knowledge, Louis Braille came up with a very logical code: the first ten letters of the alphabet are formed using combinations only of the top two rows in the cell; the next ten are the same as the first ten with the addition of the bottom dot in the left-hand column, and the following ten letters use the bottom dots in both columns. After that only the bottom right-hand dot is used, and so on. Punctuation marks are represented by combinations of dots using only the two bottom rows. Louis Braille, however, did not stop after inventing the braille alphabet; he is also responsible for adapting his system for mathematics, creating a clever system of abbreviations, and for music, developing a vertical system that is still used to this day. Braille and new technologies We do not have accurate figures on the number of braille users, nor do we have research showing a correlation between the use of the reading and writing system and academic qualifications. However, from the information we do have and available estimates we can deduce it is used by a minority of the blind and low vision. This is for a variety of reasons, among them the difficulties older people have in learning braille and the high cost of producing braille resource material. In addition, in recent times we have witnessed the development of new technologies based on text to speech which have reduced noticeably the extent to which braille is used, especially because a lot of information and books are easier to get hold of using electronic methods. Both methods, however, far from being mutually exclusive, can complement each other. In the 80s and 90s there were significant breakthroughs in computing and electronics, and we are now able to produce much more material in braille a lot more cheaply. Suitable complementary computer programmes make it possible to present the same information that is written on the computer in braille. There are now many resources that are an improvement on what most people used to have, but for people with a visual impairment many of these technological breakthroughs have opened up possibilities that were previously unimaginable. For example, a huge amount of information can now be stored on a CD-ROM, a DVD or other tiny storage devices that are now available and accessible to more and more people with vision loss who use a computer. Internet also opens up brand new horizons for those of us who cannot see but have access to an adapted computer. Reading the newspaper is now no longer a utopian pipe dream for the blind. Nevertheless, the truth is that all these innovations do not take anything away from the value of braille, and in fact they contribute to strengthening its merit. Nowadays the ideal system is to combine braille and text-to-speech software when using a computer and, more generally, when handling information. Braille as a universal system Although braille is used by a minority of people with vision loss, it must be recognised as a truly universal system since it is used in all languages, including Chinese, Japanese and Arabic. In the last few years it has also been applied in minority languages such as Guaraní, widely spoken in many parts of Paraguay, Tibetan and Dzongkha, one of Bhutan’s official languages. In Africa, braille has expanded recently to include Kinyarwanda and Kirundi, the official languages in Rwanda and Burundi respectively. The World Braille Council, set up under the auspices of UNESCO in 1950, played a leading role in the application of braille in the written languages of the world. It carried out the very important task of preserving unity in dots that were common to several languages and made a vital contribution to extending braille to languages less widespread than English, French or Spanish. Its chairman at the time, Sir Clutha Mackenzie, published World Braille Usage in 1953, a magnificent work that sets out general principles and includes braille alphabets in those languages where they were available at the time. The World Braille Council then came under the wings, firstly, of the World Council for the Welfare of the Blind (WCWB) and later, following its foundation in 1984, of the World Blind Union. Information has led to change in the main linguistic groups and in specific languages. These changes have been undertaken without taking other languages into account and without the involvement of a universal authority, thus leading to less consistency in the use of certain punctuation marks such as, for instance, brackets, even in closely-related languages like French, English and Spanish, while there is still a wide range of alternative forms of representing the now ubiquitous "@" in E-mail addresses. Unification is, for many, a desirable objective, but the goal is difficult to achieve when it involves giving up things one considers to be the best for one’s own language. An international braille code does exist and is used more and more, but the WBU Braille Council still has an important task ahead of it to unify and promote it. Louis Braille (1809-1852) 1809: Louis Braille was born on January 4th in Coupvray, a small town east of Paris. 1812: at the age of three, he accidentally stabbed himself in the eye with an awl when he was playing in his father’s saddle-maker’s workshop. The infection spread to his other eye and he became totally blind. 1819: Louis joined the Young Blind People’s Institute in Paris, founded in 1784 by Valentin Haüy. He stayed at the Institute for 24 years, first as a student and later as a teacher. 1820: Braille was introduced to the night writing system developed by army captain Nicolas-Marie-Charles Barbier for the army. He studied the system, made some improvements and developed his own method, which he completed in 1825 when he was just 15 years old. 1827: Braille became a teacher at the Young Blind People’s Institute, where he taught grammar, history, geography, arithmetic, algebra, geometry, piano and cello. 1829: the first version of his method was published. The second version, including some improvements, was published eight years later and contains the braille method as we know it today. 1852: on January 6th, Braille died of tuberculosis aged 43. He was buried in Coupvray, where the house in which he was born still stands and is now a museum. 1952: Braille’s body was moved to the Pantheon in Paris, not far from the Young Blind People’s Institute where he spent most of his life.
