Louis Braille and Voltaire rest in the Pantheon in Paris

20130626-153348.jpg Voltaire was a French Enlightenment writer, historian and philosopher.
Louis Braille invented a way for people with blindness to read. Braille was based on a tactile military code called night writing that was developed by Charles Barbier. Napoleon wanted a way for his soldiers to communicate silently at night and without any light so Barbier used raised dots for the men to feel. Because of new technology for sight-impaired people to read and write, Braille usage has declined considerably.
