François-Clément Théodore Dubois (24 August 1837 – 11 June 1924) was born in Rosnay in Marne. He studied first under Louis Fanart (the choirmaster at Reims Cathedral) and later at the Paris Conservatoire under Ambroise Thomas. He won the Prix de Rome in 1861. In 1868, he became choirmaster at the Church of the Madeleine, and in 1871 took over from César Franck as choirmaster at the Basilica of Sainte-Clotilde. In 1877, Dubois returned to the Church of the Madeleine, succeeding Camille Saint-Saëns as organist there. From 1871 he taught at the Paris Conservatoire, where his pupils included Pierre de Bréville, Guillaume Couture, Gabrielle Ferrari, Gustave Doret, Paul Dukas, Achille Fortier, Xavier Leroux, Albéric Magnard, Édouard Risler, Guy Ropartz, Spyridon Samaras, and Florent Schmitt.)
Although he wrote many religious works, Dubois had considerable hopes for a successful career on the operatic stage. His fascination with Near-Eastern subjects lead to the composition to his first staged work, La guzla de l'émir. His music also includes ballets, oratorios and three symphonies. His best known work is the oratorio Les sept paroles du Christ ("The Seven Last Words of Christ" ); his Toccata in G (1889), for the organ, is a recital staple, by no means solely in France. The rest of his large output has almost entirely disappeared from view. He has had a more lasting influence in teaching, with his theoretical works Traité de contrepoint et de fugue (on counterpoint and fugue) and Traité d'harmonie théorique et pratique (on harmony) still being sometimes used today.
"Adoramus te, Christe", from (Les sept paroles du Christ) is heard in a lovely arrangement for organ solo by Pierre Gouin.
