Decapoint

As Raphigrafie or Raphigraphie (also: Raphigraphy ) was later called by Louis Braille in 1839 also developed point font for the display of the Latin letters.

After the Braille of Louis Braille slowly sat as effective Braille with his students and peers, a new problem arose: Braille's classmates now wanted to write letters home, but no one there could read their writing. Therefore, Louis Braille developed another Braille system, which helps the blind students could also write family and friends, who did not know Braille.

In 1839 he published his writing in the form of long columns of figures that help the small and capital letters of the Latin alphabet and numbers and punctuation marks could be formed only of points that followed a strict grid. His letters were ten points high and varies widely, which is why the Scripture in English was named Decapoint. Through the numerical code and the blind were able to write Latin letters for the first time, clean.

These letters were not easy to write because of their height of ten points despite grid for the blind. It therefore did not take long to Braille 's blind friend François- Pierre Foucault 1841, the first apparatus, the Raphigraph, was built, which could push all the points of a column of characters at a time into the paper. This font was named Raphigraphy.

When the first typewriters were invented, they repressed, despite the impossibility for the blind to read their writing, quickly complicated Raphigrafie. Thus it was forgotten, but still the Raphigrafie was (or Decapoint ), the first digital font at all.
