Dumas, Alexandre, fils (1824–95), French dramatist, natural son of the above, who approached the theatre by way of a dramatization of his own novel
La Dame aux camélias (1848). First acted in 1852, this became one of the outstanding theatrical successes of the second half of the 19th century, and is still occasionally revived. As
Camille, it was equally popular in England, America, and Italy; but in spite of its success it was destined to remain the younger Dumas's only Romantic play. He turned to social drama and, though himself an agnostic, sought to enforce Christian virtues and conventional morality by using the stage as a pulpit, as in
Les Idées de Madame Aubray (1867). Dumas had little liking for the bohemian society in which his childhood had been passed and which he summarized in the title of his play
Le Demi-Monde (1855). The bitterness of his own illegitimacy found expression in
Le Fils naturel (1858) and
Un père prodigue (1859), while the question of sexual morality was ventilated in such plays as
La Femme de Claude (1873), L'Étrangère (1876), and his last play
Francillon (1887). Only occasionally, as in
La Question d'argent (1857), did he deal with social issues of more general interest, and most of his plays have disappeared with the conditions which gave rise to them. In his own day a popular and powerful social dramatist, he is now remembered only by his least typical work,
La Dame aux camélias, on which Verdi based his opera
La Traviata (1853).
