Jean Francois Casimir Delavigne was a French poet and dramatist. He was born in 1793 at Havre and died in 1843. At the restoration he published a set of elegies, entitled Les Messeniennes, which deplored the faded glories of France. He produced in 1819 his tragedy of Les Vepres Siciliennes; Lea Comediens appeared in 1820, and the tragedy of Le Paria in 1821. Of his other plays which followed these may be mentioned: L'Ecole des Vieillards; Marino Faliero; and the dramas of Louis XI - founded on Cornmines' Memoirs and Quentin Durward - and Don Juan d'Autriche. His hymn's La Parisienne and La Varsovienne, and the ballad La Toilette de Constance, are among his more popular poetical pieces. He died a member of the Academy. Research Jean Delavigne
