Plume, a widow with extensive business connections, appears for the first time in 1321. She was the founder of the most influential Jewish family in Klosterneuburg and of the Jewish community there. Plume bought a house, formerly belonging to the castle, in which a synagogue was established. She was the mother of Hetschlein and Rotlein-Judlein who also engaged in moneylending. Her son-in-law Abraham, husband of daughter Rachel/Redl, served as a rabbi. Her grandson, David Steuss, became in Austria the most prominent and influential Jew of his times. She died soon after 1346.
