"Cosima Wagner (born Francesca Gaetana Cosima Liszt; 24 December 1837 – 1 April 1930) was the daughter of the Hungarian pianist and composer Franz Liszt and Franco-German romantic author Marie d'Agoult. She became the second wife of the German composer Richard Wagner, and with him founded the Bayreuth Festival as a showcase for his stage works; after his death she devoted the rest of her life to the promotion of his music and philosophy. Commentators have recognised Cosima as the principal inspiration for Wagner's later works, particularly Parsifal.
In 1857, after a childhood largely spent under the care of her grandmother and with governesses, Cosima married the conductor Hans von Bülow. Although the marriage produced two children, it was largely a loveless union, and in 1863 Cosima began a relationship with Wagner, who was 24 years her senior. She married him in 1870; after his death in 1883 she directed the Bayreuth Festival for more than 20 years, increasing its repertoire to form the Bayreuth canon of ten operas and establishing the festival as a major event in the world of musical theatre." - (en.wikipedia.org 06.07.2021)
