D'Hermanoy sang with the Brussels opera for four seasons, and for three seasons in
Cairo. During
World War I, unable to return from France to Belgium, she went instead to Switzerland, where she sang with the Geneva Opera and volunteered as a Red Cross nurse, giving rise to her billing as "the Florence Nightingale of Song". She sang at the Belgian celebration of the end of war, and for a season at the
Royal Opera House in
Covent Garden in 1920. In 1922 she was in the cast of Massenet's
Manon in New York, with
Tito Schipa and
Edith Mason. She toured with the Chicago Civic Opera's productions of
Namiko-San (1925) in Chicago, with
Tamaki Miura,
La Traviata (1926, 1927, 1928, 1929, 1930) with
Claudia Muzio and Tito Schipa,
Rigoletto (1926, 1927, 1928) with
Charles Hackett and
Devora Nadworney,
Lucia di Lammermoor (1926, 1930, 1931), and
Il trovatore (1927, 1928, 1930). In 1931 she toured with the Chicago Civil Opera to California and the Pacific Northwest. Alice D'Hermanoy also kept poultry at her farm in Belgium. She attended poultry shows in the United States to buy birds, and reportedly sang arias for her chickens to improve them. ==Personal life==
