Leonie Rysanek

She was appointed curator of the Vienna Festival a few months after her retirement, a post she held until her death in Vienna at age 71 (she had been diagnosed with bone cancer during her last Met performances). Two days later, a Metropolitan Opera production of Wagner's Lohengrin with Ben Heppner in the title role was dedicated to her memory. In that opera, she had sung the role of Ortrud in the 1985–86 production.

Leonie Rysanek's voice is regarded as in-line with the spinto and dramatic soprano categories. Although her voice fell in the upper end of the jugendlich-dramatisch and dramatischer Sopran categories in the German repertoire, it was exclusively dramatic by Italian operatic standards. Her endurance in the high tessitura of Strauss' operas is widely praised.

She is known for singing the music of Richard Strauss. She was especially praised as the Empress (Kaiserin) in Die Frau ohne Schatten, the title role in Salome, the Marschallin in Der Rosenkavalier and Chrysothemis in Elektra. She occasionally sang Ariadne/Prima Donna in Ariadne auf Naxos and female leads in Strauss operas rarely staged (Die ägyptische Helena and Die Liebe der Danae). However, cautious of playing out of her league, she didn't tackle Salome until 1972 when she was age 46, although she kept the role of Sieglinde in her active repertoire from her early 20s until age 62. She avoided offers to sing Isolde in Wagner's Tristan und Isolde despite speculation that the role would be perfect for her. She sang Brünnhilde in Die Walküre in 1950 in Innsbruck but did not return to this role. She stated in interviews that her great respect for her colleague Birgit Nilsson was a factor in her avoidance of that soprano's signature roles. One of her performances in Die Walküre took place in the same week as her appearance as Gilda in Rigoletto.
