[2] Sieg studied first under his father and then at the Conservatoire de Paris under François Benoist (organ) and Ambroise Thomas (composition).

[a] The cantata premiered on 18 November 1864 at the Paris Opera with Jean Morère in the title role and was well received.

[4] Ivanhoé proved to be Sieg's only major composition, although he later published several piano pieces including Trois Impromptus, Tarentelle and Caprice-Valse.

After he returned from Rome where he had worked on composing an opéra-comique, he took up a post in Paris as organist at the church of Notre-Dame de Clignancourt and devoted himself to teaching.

He also served as the organist of the Church of Saint-Merri and as the singing inspector for Paris city schools.
