Rosl Schwaiger (5 September 1918 – 19 April 1970) was an Austrian operatic coloratura soprano. She was a member of the Vienna State Opera and the Bayerische Staatsoper, known for singing Mozart roles such as Blonde, Susanna and Zerlina. She appeared at European opera houses and festivals and was especially popular at the Salzburg Festival, where she appeared for decades in opera and sacred concerts.
Schwaiger also appeared in operetta, including Arsena in Der Zigeunerbaron by Johann Strauss.[2] In 1952 she performed the leading role in the WDR production of the operetta The Geisha by Sidney Jones, directed by Franz Marszalek. In 1966 Schwaiger, who had been appointed a Bavarian Kammersängerin, sang the role of Maria at the premiere of the Salzburger Passion by Cesar Bresgen at the Großes Festspielhaus in Salzburg.[1]
In 1954 Schwaiger undertook a successful tour of North America. Three years later she sang at the Glyndebourne Festival Opera as Blonde, Papagena, and Najade in Ariadne auf Naxos by Richard Strauss.[1] She gave lieder recitals in Greece and Turkey in 1958.[1]
