Königswarter family

Königswarter (French: Kœnigswarter) is a Jewish Austrian-Hungarian noble family originating from Königswart, Bohemia. In the middle of the eighteenth century, their ancestor Jonas Hirsch Königswarter emigrated to Fürth, Bavaria, where he established a business that made him wealthy. At his death (1805) he left five sons, who founded banking houses successively in Frankfurt, Vienna, Amsterdam, and Hamburg.
