Louis Braille
Louis Braille (4 January 1809 - 6 January 1852) was a French inventor. He was born in Coupvray. He invented the script braille system, which helps blind people to read. Braille is read by passing one's fingers over characters made up of an arrangement of one to six raised points. It has been adapted to almost every known language. Numbers can be written normal in Braille and there are as well some short forms for common words.
