Félix-Alexandre Guilmant (1837-1911), French organist and composer, was the organist of La Trinité from 1871 until 1901 and was a well-respected performer and improviser. Guilmant helped found the Schola Cantorum de Paris. He was appointed as Professor of Organ at the Paris Conservatoire in 1896.

Although Guilmant is best known for his extensive solo organ output, he was quite skilled as an orchestrator as evidenced by two of his organ sonatas which were successfully transformed into symphonies for organ and full orchestra.  In addition to Symphonie nos. 1 and 2, included here are two other lesser known works, the Final alla Schumann based on a French Noel and the reverent "Two Pieces" (two sections titled "Marche Elegiaque" and "Adoration").
