This study is the first to essay a systematic examination of the statements made by turn-of-the-century Viennese author Arthur Schnitzler (1862-1931) on Judaism and anti-Semitism. They are unique from various points of view, including their number, their continuity, and the long stretch of time they extend over (1880-1931). Over and above that, they are the expression of an intensive and many-sided engagement with Schnitzler's own Jewishness, with Austria, and with German culture. Further, they are remarkable for their seismographic sensitivity to anti-Semitic tendencies of any kind, a quality that was anything but widespread at the time.
