లూయీ బ్రెయిలీ జీవిత చరిత్ర
Louis Braille (4 January 1809 – 6 January 1852) was a French educator and inventor of a reading and writing system for use by people who are visually impaired. His system remains virtually unchanged to this day, and is known worldwide simply as braille.
Braille was blinded at the age of three in one eye as a result of 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 nevertheless, he 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 the system invented by Charles Barbier, Braille constructed a new method that 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.
In adulthood, Louis 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.
