When Jews in the Austro-Hungarian Empire were required to assume last names, some chose the nicest ones they could think of and may have been charged a registration fee by the authorities.
According to the YIVO Encyclopedia, “The resulting names often are associated with nature and beauty. It is very plausible that the choices were influenced by the general romantic tendencies of German culture at that time.” These names include: Applebaum — apple tree; Birnbaum — pear tree; Buchsbaum — box tree; Kestenbaum — chestnut tree; Kirshenbaum — cherry tree; Mandelbaum — almond tree; Nussbaum — nut tree; Tannenbaum — fir tree; Teitelbaum — palm tree.
