German and Jewish (Ashkenazic): habitational name from a place on the Rhine, between Mainz and Worms, so named from an unexplained first element + Old High German heim ‘homestead’. There was an important Jewish settlement here before the Holocaust. Due to persistent persecution, members of the Oppenheim community were periodically forced to flee from their native city and hence the surnames Oppenheim and Oppenheimer became widespread throughout southern and western Germany.
History: This is one of the old Ashkenazic surnames. In Eastern Europe, it was used by rabbinical families well before the mass adoption of surnames by local Jews at the turn of the 19th century.
