Louis Braille

Louis Braille is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Louis Braille rather than just read about it. In short: Louis Braille ( brayl; French: [lwi bʁɑj]; 4 January 1809 – 6 January 1852) 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.

Key takeaways

  • Louis Braille belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Louis Braille to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Louis Braille from memory before moving on to harder problems.

Reference excerpt

Louis Braille ( brayl; French: [lwi bʁɑj]; 4 January 1809 – 6 January 1852) 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. Braille was blinded in one eye at the age of three. This occurred as a result from an accident with a stitching awl in his father's harness-making shop. Consequently, an infection set in and spread to both eyes, resulting in total blindness. At that time, there were not many resources in place for the blind, but he nevertheless excelled in his education and received a scholarship to France's Royal Institute for Blind Youth. While still a student there, he began developing a system of tactile code that could allow blind people to read and write quickly and efficiently. Inspired by a system invented by Charles Barbier, Braille's new method was more compact and lent itself to a range of uses, including music. He presented his work to his peers for the first time in 1824, when he was fifteen years old. In adulthood, Braille served as a professor at the Institute and had an avocation as a musician, but he largely spent the remainder of his life refining and extending his system. It went unused by most educators for many years after his death, but posterity has recognized braille as a revolutionary invention, and it has been adapted for use in languages worldwide.

Early life

Louis Braille was born in Coupvray, a small town about twenty miles east of Paris, on 4 January 1809. He and his three elder siblings – Monique Catherine (b. 1793), Louis-Simon (b. 1795), and Marie Céline (b. 1797) – lived with their parents, Simon-René and Monique, on three hectares of land and vineyard in the countryside. Simon-René maintained a successful enterprise as a leatherer and maker of horse tack. As soon as he could walk, Braille's time was spent playing in his father's workshop. At the age of three, he was playing with some of the tools, trying to make holes in a piece of leather with an awl. Squinting closely at the surface, he pressed down hard to drive the point in, and the awl glanced across the tough leather and stabbed him in one of his eyes. A local physician bound and patched the affected eye and even arranged for Braille to be met the next day in Paris by a surgeon, but no treatment could save the damaged organ. In agony, the young boy suffered for weeks as the wound became severely infected. He eventually lost sight in the other eye, likely due to sympathetic ophthalmia. Braille survived the torment of the infection, but by the age of five he was completely blind in both eyes. Due to his young age, he did not realize at first that he had lost his sight, and often asked why it was always dark. His parents made many efforts – quite uncommon for the era – to raise their youngest child in a normal fashion, and he prospered in their care. He learned to navigate the village and country paths with canes his father hewed for him, and he grew up seemingly at peace with his disability. Braille's bright and creative mind impressed the local teachers and priests, and he was accommodated with higher education.

Blind education Braille studied in Coupvray until the age of ten. Because of his intelligence and diligence, Braille was permitted to attend one of the first schools for blind children in the world, the Royal Institute for Blind Youth, since renamed to the National Institute for Blind Youth in Paris. The last of his family's children to leave the household, Braille departed for the school in February 1819. At that time the Royal Institute was an underfunded, ramshackle affair, but it provided a relatively stable environment for blind children to learn and associate together. While a student at the school, Braille made lifelong friends, including Gabriel Gauthier, Hippolyte Coltat, and Jean-Pierre Binet.

Haüy system

The children were taught to read using a system devised by the school's founder, Valentin Haüy. Not blind himself, Haüy was a philanthropist who devoted his life to helping the blind. He designed and manufactured a small library of books for the children by embossing heavy paper with the raised imprints of Latin letters. Readers would trace their fingers over the text, comprehending slowly but in a traditional fashion which Haüy could appreciate. Braille was helped by Haüy's books, but he also despaired over their lack of depth: the amount of information retained in such books was necessarily minor. Because the raised letters were made in a complex artisanal process using wet paper pressed against copper wire, the children could not hope to "write" by themselves. So that the young Louis could send letters back home, Simon-René provided him with an alphabet made from bits of thick leather. It was a slow and cumbersome process, but the boy could at least trace the letters' outlines and write his first sentences. The handcrafted Haüy books all came in uncomfortable sizes and weights for children. They were laboriously constructed, very fragile, and expensive to obtain: when Haüy's school first opened, it had a total of three books. Nonetheless, Haüy promoted their use with zeal. To him, the books presented a system which would be readily approved by educators and indeed they seemed – at the time – to offer the best achievable results. Braille and his schoolmates, however, could detect all too well the books' crushing limitations. Nonetheless, Haüy's efforts still provided a breakthrough achievement – the recognition of the sense of touch as a workable strategy for sightless reading. The Haüy system's main drawback, in the opinion of at least one author, was that it was "talking to the fingers with the language of the eye".

Worked examples

Example 1 — a first encounter with Louis Braille

Start with the simplest possible case. Write down what Louis Braille claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Louis Braille before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Louis Braille ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Louis Braille

In research
Louis Braille appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Louis Braille in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Louis Braille is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1809 births, 1852 deaths, 19th-century French inventors, so understanding it makes those chapters shorter.
In everyday life
Look for Louis Braille outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
