Luise Helletsgruber (1901-1967) was an Austrian soprano, active in opera and concert repertory. She sang at the Vienna State Opera and in important interwar recordings.

In the Pristine catalogue she appears in Weingartner’s 1935 Beethoven Ninth and in Fritz Busch’s Le nozze di Figaro from Glyndebourne.

Helletsgruber’s singing brought Viennese poise, clarity and lyric charm to repertory ranging from Beethoven to Mozart opera.

Her page is justified by repeated catalogue presence and historical context. Helletsgruber gives the early Mozart and Beethoven shelves a bright Austrian soprano line.
