9413 Eichendorff           Discovered 1995 Sept. 21 by F. Börngen at Tautenburg.
Named for the Silesian poet Joseph Freiherr von Eichendorff (1788-1857). He studied philosophy and law in Halle and Heidelberg. From 1816 to 1844, he was in the Prussian civil service. The most popular writer among the German romanticists, he sings of nature, walking, the woods and the night. The highlights of his work, some of which have been set to music, include "In einem kühlen Grunde", "O Täler weit, o Höhen", "Wer hat dich, du schöner Wald"). His most beautiful short story is "Aus dem Leben eines Taugenichts".
