In 19th century, the Central Association of German Citizens of Jewish Faith began to publish lists of spas and hotels at which Jewish guests were not welcome. Some resorts even advertised themselves as judenfrei (“free of Jews”). After World War I, the phenomenon known as Bäder-Antisemitismus (“spa antisemitism”) increased, and with the Nazi rise to power in 1933, it became official policy. By 1935, Jews had been effectively banned from the Northern German bathing resorts, and from spas in the interior of the country by 1937. It was not until the Anschluss in March 1938 that Jews were pushed out of Austrian spas as well. Bad Ischl and other locations in the Salzkammergut region were particularly popular with Jews, to the point that in 1922, the Austrian-Jewish writer Hugo Bettauer quipped that “it caused a stir when people suspected of being Aryans showed up.” In a notice from June 2, The Jewish Telegraphic Agency reports that at the behest of the Nazi commissioner in charge, Jews were to be “segregated in Jewish hotels and pensions” and were no longer permitted to attend cultural events in Bad Ischl.
