A noctograph is a writing instrument composed of a piece of paper whose underside is treated with printer's ink carbon paper and a metal board with clips to hold the paper in place and guidelines to make for straight writing in the dark. The user writes with a metal stylus. The original purpose was to allow the blind or partially sighted to write with more ease than with a traditional pen, although it has also been used by the fully sighted to write in the dark.[1] It was originally patented by Ralph Wedgwood in 1806.
