Cosima Wagner
Cosima Wagner (née Liszt; 24 December 1837 – 1 April 1930) was the illegitimate daughter of composer Franz Liszt and author Marie d'Agoult, who became the second wife of Richard Wagner and a central figure in preserving his musical legacy.[1][2] Born in Bellagio, Italy, she married conductor Hans von Bülow in 1857, bearing two daughters, before beginning an affair with Wagner that resulted in three children: Isolde, Eva, and Siegfried.[1][3] Divorcing Bülow in 1869, she wed Wagner in 1870 and supported his work at Tribschen and Bayreuth, including the festival's founding in 1876.[4] Following Wagner's death in 1883, Cosima assumed directorship of the Bayreuth Festival, managing it until 1908 and ensuring the performance of his major operas in dedicated settings, thereby establishing it as a pilgrimage site for Wagnerian devotees.[5][3] Her diaries, spanning 1869 to 1883, provide detailed insights into Wagner's creative process and domestic life, though they also reflect her own pronounced views on culture, politics, and Judaism, which aligned with and amplified her husband's ideologies.[1] Known for her unyielding commitment to Wagner's vision, she resisted modern interpretations and maintained traditional stagings, shaping the festival's character amid financial and artistic challenges.[4][3]
