[1] Saint-Hubert offered the patronage to Hereditary Grand Duchess Marie-Adelaide, but she declined, as a Roman Catholic feminist organisation was due to be set up.
This campaign achieved success in 1911 when the Chamber of Deputies unanimously voted to establish publicly funded girls' schools in Luxembourg City and Esch-sur-Alzette.
[5] She and her husband moved to Colpach in 1920, and after the war they received many German and French intellectuals here under the name of Cercle de Colpach, such as Paul Claudel, Jean Guéhenno, Jacques Rivière, Karl Jaspers, Bernard Groethuysen, André Gide, Jean Schlumberger, Ernst Robert Curtius, Annette Kolb and Richard von Coudenhove-Kalergi.
From 1898, she published articles on German painters and literary criticisms, amongst others on L'Immoraliste by André Gide, in the Belgian avant-gardist review L'Art moderne.
It was in this same review that she published articles on the intellectual situation in Germany after the First World War, as well as her autobiographical travel account Paysages de la trentième année, which, starting in the island sceneries of Corsica and Iceland, evoked the confrontation with emptiness, absurdity and nothingness.
In collaboration with Marie Delcourt and Bernhard Groethuysen, Aline Mayrisch also translated the sermons of the medieval mystic Meister Eckhart, L'enfant qui s'accuse by Jean Schlumberger and Le mythe de Sisyphe.
