For 10 points, name this French organist and composer of the Symphony in D Minor.
The Andante Quietoso in E-flat minor and Grand Duo for Piano and Violin are respectively numbered five and six in Wilhelm Mohr's catalogue of this man's work.  His final works were his Trois Chorales and one collection includes his piece Cantabile as well as a rhapsody on two themes known as the Piéce Heroique. Another collection contains the complicated Prélude, Fugue, et Variation, as well as a Pastorale, a Priére, and the famous (*) Grand Piéce Symphonique. The latter piece frequently draws comparison to an even larger work dedicated to his student Henri Duparc and is noted for the melody of the English horn over the harp and strings in the Allegretto second movement.
