Oscar Ludwig Levy (28 March 1867 – 13 August 1946) was a German Jewish physician and writer, now known as a scholar of Friedrich Nietzsche, whose works he first saw translated systematically into English. His was a paradoxical life, of self-exile and exile, and of writing on and (as often taken) against Judaism. He was influenced by the racialist theories of Arthur de Gobineau. He also admired Benjamin Disraeli, two of whose novels he translated into the German language.
