question: What group was the author of "The Assignment" a member of?
answer: Gruppe Olten
context: Title: The Assignment (novella)
  Passage: Der Auftrag (English: The Assignment , subtitled "Or, on the Observing of the Observer of the Observers") is a 1986 novella by the Swiss writer Friedrich Dürrenmatt.  The first English publication appeared in 1988, translated by Joel Agee.  The experimental narrative is divided into twenty-four parts, each one a single sentence spanning many pages.  In his forward to the 2008 English language edition, Theodore Ziolkowski notes that the inspiration for the twenty-four sentence structure came after listening to a recording of Glenn Gould performing the first half of Bach's "The Well-Tempered Clavier I", itself a work in twenty-four movements.  Inspiration for the plot came from the Austrian poet Ingeborg Bachmann's unfinished novel "The Franza Case", which Dürrenmatt's second wife, documentary filmmaker Charlotte Kerr, was attempting to turn into a film at the time of their meeting.
