Johannes Hadlaub
German musician
Johannes Hadlaub (fl. 1300, d. before 1340) was one of the Minnesingers whose works are recorded in Codex Manesse. He was a citizen of Zürich, and is on record as buying a house there in 1302.
This assumption was fictionalised in a poetic novella, "Hadlaub" (in the Züricher Novellen, 1878), by Gottfried Keller.
