From 1839 to 1841, Dumas, with the assistance of several friends, compiled Celebrated Crimes, an eight-volume collection of essays on famous criminals and crimes from European history. He featured Beatrice Cenci, Martin Guerre, Cesare and Lucrezia Borgia, as well as more recent events and criminals, including the cases of the alleged murderers Karl Ludwig Sand and Antoine François Desrues, who were executed.
Alexandre Dumas (24 July 1802 – 5 December 1870), also known as Alexandre Dumas, père, was a French writer. His works have been translated into nearly 100 languages, and he is one of the most widely read French authors. Many of his historical novels of high adventure were originally published as serials, including The Count of Monte Cristo, The Three Musketeers, Twenty Years After, and The Vicomte de Bragelonne: Ten Years Later. His novels have been adapted since the early twentieth century for nearly 200 films. Dumas' last novel, The Knight of Sainte-Hermine, unfinished at his death, was completed by a scholar and published in 2005, becoming a bestseller. It was published in English in 2008 as The Last Cavalier.
Prolific in several genres, Dumas began his career by writing plays, which were successfully produced from the first. He also wrote numerous magazine articles and travel books; his published works totaled 100,000 pages. In the 1840s, Dumas founded the Théâtre Historique in Paris
The English playwright Watts Phillips, who knew Dumas in his later life, described him as, "the most generous, large-hearted being in the world. He also was the most delightfully amusing and egotistical creature on the face of the earth. His tongue was like a windmill – once set in motion, you never knew when he would stop, especially if the theme was himself."
