Von Geldern is a nobiliary predicate, borne by several relatives of the German poet Heinrich Heine. Members of Heine’s family who were ennobled adopted the predicate von along with the name Geldern, reflecting their elevation to Austrian nobility rather than indicating a separate hereditary family name.https://www.jewishencyclopedia.com/articles/7505-heine-gustav-freiherr-von-geldern?
