At an early age, she commenced the study of singing and pianoforte at the Academy of Budapest.

Her first public appearance as a coloratura soprano under the name of Alpár was in 1923 at the Budapest State Opera House.

The debut marked the beginning of a long career, promoted by eminent conductors such as Erich Kleiber, which led her singing at the great opera houses of Vienna, Berlin, and all over the world.

An ensemble member of the Berlin State Opera from 1927 to 1930, she excelled in performances of Mozart's The Magic Flute, Rossini's The Barber of Seville, as well as in Verdi's Rigoletto and La Traviata.

Alpár appeared on "Hitler's hit list", along with Charlie Chaplin and others, in the pages of the anti-semitic book, Juden sehen Dich an by Johann von Leers.
