Dion Boucicault, Irish-American actor and playwright (born 1820)

Dionysius Lardner "Dion" Boucicault was an Irish actor and playwright famed for his melodramas. By the later part of the 19th century, Boucicault had become known on both sides of the Atlantic as one of the most successful actor-playwright-managers then in the English-speaking theatre. The New York Times hailed him in his obituary as "the most conspicuous English dramatist of the 19th century"; he and his second wife, Agnes Robertson Boucicault, applied for and received American citizenship in 1873.
