Why was Braille invented?
Louis Braille invented the Braille system in 1824 to enable the blind to read by using a combination of 6 raised dots for each letter or number. These could be read by the blind with their fingertips. Braille’s system was based on an idea of Charles Barbier, a French army officer, who used a combination of 12 dots pressed into paper for each number or letter in military communications that could be read in the dark of night.
