Louis Braille was born in 1309 in Coup ray. He was a French teacher of the blind. He himself was blind from the age of three, and in 1818 he went to the National Institute for the Young Blind in Paris. Soon showing marked ability in both science and music, he became famous in Paris as an organist and violoncellist. In 1826 Braille began teaching the blind in the institute. Braille is known for his idea of modifying the Briberies. Point writing consists of embossed dots and dashes on cardboard; the Braille system derived from it is used successfully today, in slightly modified form, and in many countries.
