Auguste Joseph-Marie François Le Guennant (10 January 1881 – 17 May 1972) was a French organist, church musician and composer.
Le Guennant studied at the Schola Cantorum de Paris – the organ with Alexandre Guilmant and composition with Vincent d'Indy.
[2] He held for some time the position of organist at the grand organ of Notre-Dame de Clignancourt,[3] and left Paris in 1905 to become head of the chapel at Notre-Dame-de-Bon-Port in Les Sables-d'Olonne, and from 1908 at the Basilica of Saint-Nicolas in Nantes.
[1] When Maurice Duruflé thought about basing his Requiem on Gregorian chant, he asked Le Guennant for advice, and gratefully acknowledged his understanding.
[5] In 1960, Duruflé dedicated a composition to Le Guennant, his Quatre Motets sur des thèmes grégoriens which were also based on chant.
