Decapoint

The reason for the development of this writing was that relatives of the students could not read braille.

These letters were not easy for the blind to write because of their height of ten dots despite grid. It therefore did not take long for the blind friend of Louis Braille, Pierre-François-Victor Foucault, to build in 1841 the first apparatus, the Raphigraph, which could push all the points of one column of characters at the same time into the paper. This font was now named Raphigraphy (Raphigrafie or Raphigraphie).

When the first typewriters were invented, they quickly replaced the complicated Raphigraphy or decapoint, despite the impossibility for the blind to read the writing of typewriters.
