EINSTEIN, Albert (1879-1955). Autograph letter signed ("A. Einstein"), in German, to Herr [Herman] Bernstein. Berlin, 6 May 1929. 1 page, 4to, on personal stationery. Einstein thanks the recipient and his friends for defending his "wretched self." He further comments: "[I] don't think taking a personality cult to such extremes is good. But I think that by doing so you wanted to serve the Jewish cause. In this regard, I thank you kindly."
