Born in Vienna, Schörg first trained for the profession of typist. In 1937, at the age of 23, she won a beauty contest and became " Queen of Danube ". That same year she made her stage debut in Ostrava at the Antonín Dvořák Theatre in the world premiere of Ödön von Horváth's play Der jüngste Tag. She spent the next two years performing at that theatre, and at theatres in Karlovy Vary, Ostrava, Marienbad, and Vienna (Theater in der Josefstadt). In 1939 she joined the opera house in Aussig (now Usti nad Labem) where she became popular as a performer in operettas. She made her professional opera debut at that house as Hannerl in Heinrich Berté's arrangement of Franz Schubert's Das Dreimäderlhaus.
