From 1947 to 1967, the writer Hans Werner Richter invited authors to the meetings of the Gruppe 47. Authors read unpublished texts aloud, and the others criticized them on the spot. The reader sat on the free chair next to Richter, which was jokingly called the elektrischer Stuhl, the electric chair. Zur wichtigen Maxime wurde, dass der Vortragende sich nicht verteidigen durfte, sowie dass die Kritik der konkreten Texte im Mittelpunkt stand. It became an important rule that the reader was not allowed to defend himself, and that the criticism focused on the actual texts. In 1958 Günter Grass read the first chapter of his still unpublished novel Die Blechtrommel at a meeting in the Allgäu and won the group’s prize.
