Johannes Hadlaub
Johannes Hadlaub (fl. c. 1300, died before 1340) was a Zurich Minnesinger and one of the last poets of Middle High German courtly song. A citizen of Zurich, he is documented buying a house there in 1302. Fifty-one of his songs survive in the Codex Manesse.
His work included love songs, dawn songs and longer lyrical compositions. Because his verse seems to have shaped the collection, scholars commonly assume he helped compile it. Gottfried Keller later made him the hero of the novella Hadlaub, which strongly influenced later perceptions of the poet.
