Claire Croiza (née Conelly, or O'Connolly) was born in Paris, the daughter of an expatriate American father and an Italian mother, and as a child she excelled at piano and singing. She was taught singing privately at first and then went to the Polish tenor
Jean de Reszke for further study. She made her opera début in
Nancy in 1905 in
Messaline by
Isidore de Lara. In 1906 she made her first appearance at
La Monnaie in Brussels, as Dalila in
Samson et Dalila, beginning a long association with that theatre which included the roles of Dido (Berlioz), Clytemnestra (
Elektra), Erda, Carmen, Léonor (
La favorite), Charlotte (
Werther) and the title role in
Fauré's opera
Pénélope. In 1910 she performed as Alays in the world premiere of
Cesare Galeotti’s
La Dorise and created the title role in the world
premiere of
Pierre de Bréville's
Éros vainqueur at La Monnaie. It was again as Dalila that she made her
Paris Opera début in 1908. Although she first established herself as an operatic singer, she increasingly developed her career as a recitalist specialising in
mélodies, and she undertook recital tours in numerous countries, including frequent visits to London where she was very well received. She had a great feeling for the French language and was always able to enunciate the words in clear and natural way without sacrificing the flow of the music. Several contemporary composers chose to accompany her personally in performances of their songs, including
Ravel (in
Shéhérazade),
Fauré (in the premiere of
Le jardin clos ),
Poulenc,
Roussel, and
Swiss-French composer Arthur Honegger. From 1922, she also worked as a teacher, giving classes in interpretation at the
École Normale, and from 1934 at the
Paris Conservatoire. Her pupils included
Janine Micheau, Suzanne Juyol, and the baritones
Jacques Jansen,
Camille Maurane and
Gérard Souzay. In 1926 Croiza gave birth to a son, Jean-Claude (1926–2003), whose father was Honegger, but the parents did not marry. She died in Paris in 1946 at the age of 63. Her reputation was concisely summed up by a reviewer in
The Times reporting on a
Wigmore Hall concert in 1932: "Mme. Croiza is a supreme interpreter of modern French songs. She brings to them an exquisite sensibility that reveals every shade of meaning in the poems." This view was reinforced in an obituary tribute also in
The Times: "Her consummate musicianship, unerring in its intuition, sensitiveness, charm and subtlety, exquisite diction and phrasing, combined with deep poetical feeling and a restrained but profoundly moving dramatic sense allied to an unusually wide culture, made her the friend and chosen interpreter of the chief contemporary French composers from Debussy to Poulenc and of the poets Valéry and Claudel." ==Recordings==
