Louis Braille's 200th birthday celebrated January 4
January 4 marks the 200th anniversary of the birth of Louis Braille; the Frenchman who developed the series of six dots that helps thousands of blind people around the world do everyday things such as read and write.
In the United Kingdom alone, there are over 18,000 adults using Braille.
From selecting a music CD, choosing a tin of baked beans over spaghetti hoops, reading music, and being able to tell the difference between aspirin and paracetamol, to taking notes at a lecture - Braille means independence for blind and partially sighted people.
David Blunkett MP said: "Braille is a choice.
"For some it means a lifeline to independence, for others, access to literature or information.
"Braille can be hi-tech, or can be produced using old-fashioned means just about anywhere in the world.
