The salon of Marie von Schleinitz, whose first marriage was to the Prussian minister of the royal household Alexander von Schleinitz (1807–1885), was among the most prominent of Imperial Germany. Influential guests from the court and cultural circles of Berlin gathered there. As an important patron of Richard Wagner, Countess von Schleinitz-Wolkenstein played a central role in establishing the Bayreuth Festspiele and helped the composer to make his breakthrough.
