In addition to his literary activity in medical science, he devoted himself to Jewish learning. Under the pseudonym "Dr. Essenna" he translated Joseph Salvador's Histoire des institutions de Moïse et du peuple hébreu into German, with an introduction by Gabriel Riesser. Under the same pseudonym he published Gedanken aus dem Tagebuche eines Juden über die Drei Grossen Propheten der Europäischen Geschichte.
