Ludwig Achim von Arnim (Carl Joachim Friedrich Ludwig Achim von Arnim) was born on January 26, 1781, in Berlin. Ludwig Achim von Arnim studied law and mathematics in Halle an der Saale and in Göttingen from 1798 until 1801.
He composed a series of articles for natural science journals and undertook an educational journey through Europe with his brother from 1801 until 1804. Of particular importance was his friendship with the poet Clemens Brentano, with whom he published the four volume collection of folk songs "Des Knaben Wunderhorn" in Heidelberg from 1806 to 1808 and the important Romantic "Zeitung für Einsiedler" ("Journal for Settlers") in 1808.
He married Brentano's sister, the writer Bettina von Arnim, in 1811 and had seven children with her. As of 1809, Arnim lived in Berlin, where he worked on Heinrich von Kleist's "Berliner Abendblätter." He stayed in close contact with Prussian nationalists such as Friedrich de la Motte, Fouqué and Kleist. In Berlin, he also founded the political group "Deutsche Tischgesellschaft" (German Table-Society) in 1811 and edited the Berlin daily paper "Der Preußische Correspondent" ("The Prussian Correspondent") in 1813 and 1814. He returned to his castle manor Wiepersdorf in 1814, though from there he still participated in the literary life of Berlin with many articles and stories in newspapers, magazines, and almanacs, as well as his own independent publications.
Next to Clemens Brentano, Ludwig Achim von Arnim is considered the chief representative of Heidelberg Romanticism. He died on January 21, 1831 in Wiepersdorf.
