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.
Prior to this system most blind schools in France used something called a Tactile alphabet, with letter forms were printed raised on the paper. Louis Braille learned this system as a child. These were expensive to print, heavy to hold and clumsy to use.
