9909 Eschenbach           Discovered 1971 Mar. 26 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.
Wolfram von Eschenbach (1168-1220) was, with von Aue and Gottfried von Strassburg, one of the greatest poets of medieval times. Beginning as a song writer, he later wrote three great epics: Parzifal, with the fragmentarian Gralsepos of Chrèstien de Troyes as a basis, and the two unfinished works Titurel and Willehalm.
