Gottfried von Strassburg (died c. 1210) is the author of the Middle High German courtly romance "Tristan", an adaptation of the 12th-century "Tristan and Iseult" legend.
 Gottfried's work is regarded, alongside Wolfram von Eschenbach's "Parzival" and the "Nibelungenlied", as one of the great narrative masterpieces of the German Middle Ages.
 He is probably also the composer of a small number of surviving lyrics.
 His work became a source of inspiration for Richard Wagner's opera "Tristan und Isolde" (1865).
Andrew C. von Eschenbach (born October 30, 1941 in Philadelphia, Pennsylvania) was the Commissioner of the United States Food and Drug Administration from 2006–2009.

 He was previously the 12th director of the National Cancer Institute.
Ulrich von Türheim (c. 1195 – c. 1250) was a German writer from the Augsburg area writing during the first half of the 13th century.
 Three of his works have survived: a conclusion to the version of the Tristan legend left unfinished by Gottfried von Strassburg; "Rennewart", a continuation of "Willehalm", left unfinished by Wolfram von Eschenbach; and fragments of a version of "Cligès" based on that of Chrétien de Troyes.
 It is not known whether this last work was a separate work or also a continuation, in this case of a now lost "Cligès" by Konrad Fleck.
 The relative chronology of these works is disputed, though "Rennewart" is generally regarded as the last.
Parzival is a medieval German romance written by the poet Wolfram von Eschenbach in Middle High German.
 The poem, commonly dated to the first quarter of the 13th century, centers on the Arthurian hero Parzival (Percival in English) and his long quest for the Holy Grail following his initial failure to achieve it.
Hartmann von Aue (born "c." 1160-70, died "c." 1210-20) was a Middle High German knight and poet.
 He introduced the courtly romance into German literature and, with Wolfram von Eschenbach ("c." 1170–"c." 1220) and Gottfried von Strassburg (died "c." 1210), was one of the three great epic poets of Middle High German literature.
 He was also a Minnesänger, and 18 of his songs survive.
Parsifal (WWV 111) is an opera in three acts by German composer Richard Wagner.
 It is loosely based on "Parzival" by Wolfram von Eschenbach, a 13th-century epic poem of the Arthurian knight Parzival (Percival) and his quest for the Holy Grail (12th century).
