In 1940, Maeterlinck and Dahon were forced to flee their home in Paris with her parents due to the advance of the Germans.[5] They arrived in the United States in July 1940, and resettled in New York City, moving into an apartment in the Hotel Esplanade.[5] After the war, they were able to return to their home "Orlamonde" in Nice in 1947.[6] Despite their age difference, friends reported them to be devoted to each other.[7]
