Kater Martinchen, collection of stories in German

According to Wikipedia: "Ernst Moritz Arndt (December 26, 1769 - January 29, 1860) was a German patriotic author and poet. Early in his life, he fought for the abolition of serfdom, later against Napoleonic dominance over Germany, and had to flee to Sweden for some time due to his anti-French positions. He is one of the main founders of German nationalism and the movement for German unification. After the Carlsbad Decrees, the forces of the restoration counted him as a demagogue and he was only rehabilitated in 1840."
