The inventor of the braille is Louis Braille, a young man of the 1821 era who discovered the braille. Braille himself is a blind. The shortcomings it becomes a motivation for himself to be able to read like people in general who see. A strong sense of learning to recognize letters raises an idea of Braille's self that is to find a way to be able to read and finally able to find the way that is forming letters with dots that arise that form letters so that blind people can recognize the letters by fingering the embossed dots.

Braille or Louis Braille is a French national youth born on January 4, 1809 in the French Coupvray. Braille suffered blindness at the age of 4 years because of his eyes pierced by a needle. At a young age at the time of school there was a soldier who visited the school that is a special school of the blind and explained about a code of soldiers at night that is known by the writing of the night. The writing tonight uses twelve dots of points. Young Braille interested in these points then refine into six points and form the writing and the series of writings are recorded so-called braille books. January 6, 1852 Braille dies in Paris France. Quoted from pramukasolid.blogspot.co.id (19/11/2016).
That is the history of braille that is very helpful for the blind. From the above we are still given the completeness of the senses should be unyielding and also grateful.
