She was an organist, teacher, and recording artist. She taught at the Paris Conservatory, where she had studied after World War II with Marcel Dupré and Maurice Duruflé.
She was the youngest child in a family of musicians. At age 11, she began assisting her father, Albert, at the organ in the church of Saint-Germain, and succeeded him there after he died in 1971.
She championed the organ works of her oldest brother, Jehan Alain, a composer who was killed in action against the German invasion of France in 1940.
I come from a musical family, and we played Bach virtually every evening, playing on the organ, singing cantatas - Bach was almost a family illness! (in an interview in British quarterly The Organ)
