In the beginning of 1929, Walser, who had suffered from anxieties and hallucinations for quite a time, went to the Bernese mental home Waldau, after a mental breakdown, at his sister Fani's urging. In his medical records it says: "The patient confessed hearing voices." Therefore, this can hardly be called a voluntary commitment. While in the mental home, his state of mind quickly returned to normal, and he went on writing and publishing. More and more, he used the way of writing he called the "pencil method": He wrote poems and prose in a diminutive Sütterlin hand( Sütterlin for short, is the last widely used form of the old German blackletter handwriting ("Spitzschrift"). In Germany, the old German cursive script developed in the 16th century is also sometimes called Fraktur the letters of which measured about a millimeter of height by the end of that very productive phase.) Werner Morlang and Bernhard Echte were the first ones who attempted to decipher these writings. In the 1990s, they published a six-volume edition, Aus dem Bleistiftgebiet ('From the pencil area'). Only when Walser was, against his will, moved to the sanatorium of Herisau in his home canton Appenzell Ausserrhoden, did he quit writing. Another reason might have been that with the rise of the Nazis in Germany, his works could no longer be published in any case. (source Wiki)
