organ and improvisation at the Nancy Conservatoire (1950–1952) and the Conservatoire Royal in Liège (1952–1968). Among her students were Marie-Madeleine Duruflé, Pierre Labric, and Louis Thiry. In 1967, after several years of negotiations, she signed a contract with Decca Records for a recording of the complete organ works by Olivier Messiaen at Notre-Dame de Paris, with which she could not comply to due to health reasons. According to her biographer, Christiane Trieu-Colleney, Demessieux underwent medical treatment and did not perform in concert for most of the last year of her life. Jeanne Demessieux died on November 11, 1968 in Paris, at age 47, from throat cancer. She was buried in the Demessieux family tomb in the Cimetière du Grau-du-Roi, not far from Aigues-Mortes. Demessieux wrote more than 30 compositions. A third of these were written for the organ, but she also produced pieces for piano, numerous songs, a handful of choral works (including an oratorio, La Chanson de Roland), and orchestral works. About half of her output has been published as of 2021. In 2021, Decca Records released an 8-CD box set with her complete recordings for this label between 1947 and 1967, including the above-mentioned 1959 world-premiere recording of Franck's complete organ works.
