Charles Gounod
Later in his life, Gounod became very interested in religion again. He wrote a lot of religious music, including his famous musical setting of Ave Maria based on the first prelude from Book I of The Well-Tempered Clavier by J.S. Bach and Hymnus Pontificius the anthem of Vatican. He also wrote two oratorios, including Mors et vita which Queen Victoria liked so much that she asked for it to be played in the Royal Albert Hall in 1886.
