Ernst Rosmer

Writing under the name Ernst Rosmer, Elsa Bernstein was a German author and playwright born in 1866 and died in 1949. She is especially associated with Königskinder, the fairy-tale drama that later became the basis for Engelbert Humperdinck’s opera.

Bernstein worked in a period when women often published under male pseudonyms, and the name Ernst Rosmer became closely linked with her dramatic writing. Her work has continued to draw interest because it connects late 19th-century literary theater with opera and musical adaptation.

Although the pseudonym can look like a separate author entry in library records, it refers to Bernstein’s literary identity rather than a different person. That makes Ernst Rosmer an especially interesting figure for readers who enjoy the overlaps between authorship, performance, and cultural history.
