Félix-Alexandre Guilmant (March 12, 1837 – March 29, 1911) was a French organist and composer. He was a student of his father, then of Jacques-Nicolas Lemmens, he became an organist and teacher in his place of birth. In 1871 he was appointed as organist of la Trinité church in Paris, a position that he held for 25 years. From then on he followed a career as a virtuoso; he gave concerts in Europe as well as in the USA.
Guilmant created the Schola Cantorum in 1894 with Charles Bordes and Vincent d’Indy. In 1896 he succeeded Charles-Marie Widor as organ teacher of Conservatoire de Paris. With André Pirro, he published a collection of scores, Archives des Maîtres de l’Orgue (archives of the masters of the organ), a compilation of the compositions of numerous classical French composers in ten volumes, from 1898 to 1914. He proceeded in the same manner for foreign masters of the organ, publishing l’École classique de l’Orgue (classical school of the organ).
Guilmant was an accomplished composer, particularly for his own instrument, the organ. His organ repertoire includes his 18 collections of Pièces dans différents styles (pieces in differing styles), the more liturgical Soixante interludes dans la tonalité grégorienne (60 pieces in Gregorian tonality) and his 12 books of l’Organiste liturgique (the liturgical organist). He also wrote chamber music, vocal music, a sinfonia cantata (Ariane) as well a lyric scene (Bathsheba).
