The twofold-exhibition (Zeitzeuge und Pioniere der Mundartdichtung) presents the travelling exhibition ‘Schweizerreise – Johann Peter Hebel as Aufklärer’ (Journey through Switzerland – Johann Peter Hebel as a philosopher of the Enlightenment) of the Dreiländermuseum and the Hebelbund in Lörrach (Germany), and a selection of manuscripts, letters and drawings from the legacy of the poet-priest and Hebel admirer Jonas Breitenstein (1828-1877) from the canton of Basel-Landschaft. Johann Peter Hebel (1760-1826) travelled through Switzerland in 1805 and recorded his observations in a travel diary. His notes offer a remarkable insight into a time when Napoleon also ruled Switzerland. Jonas Breitenstein is considered one of the most influential authors of his canton. He was the first to publish in the Baselbieter dialect. The exhibition offers uncommon and good insight into this period of the nineteenth century.
