It was only after King Ludwig II of Bavaria became a sponsor of Wagner (he granted the composer a generous stipend, and supported Wagner's artistic endeavours in other ways) that enough resources could be found to mount the premiere of "Tristan und Isolde". Hans von Bülow was chosen to conduct the production at the Nationaltheater in Munich, despite the fact that Wagner was having an affair with his wife, Cosima von Bülow. Even then, the planned premiere on 15 May 1865 had to be postponed until the Isolde, Malvina Schnorr von Carolsfeld, had recovered from hoarseness. The work finally premiered on 10 June 1865, with Malvina's husband Ludwig partnering her as Tristan.
