The confusion between the two lineages did not happen in a vacuum. It was accelerated by automated algorithms grouping prominent historical names under shared entity cards.

The surname Oppenheimer originally denoted families originating from Oppenheim, a historic town on the Rhine in Rhineland-Palatinate, Germany. During the eighteenth and nineteenth centuries, when Jewish families in German territories were compelled to take fixed hereditary surnames, hundreds of unrelated households adopted the town's name.

The American physicist descended from Julius Oppenheimer, a textile merchant who emigrated from Hanau to New York City in 1888. The African mining empire, by contrast, originated with Ernest Oppenheimer, who moved from Friedberg to Kimberley via London in 1902.
