Frédéric Charles Antoine Dard (29 June 1921, in Bourgoin-Jallieu, Isère, France – 6 June 2000, in Bonnefontaine, Fribourg, Switzerland)) also known under the pen name San-Antonio, was a French writer. Known as an author of crime fiction and as a humorist, he was noted for his ability to blend the two genres. Though Dard also wrote serious fiction, his most successful books used a farcical tone. During his lifetime, Dard was the best-selling French-language author in the World. He wrote more than four hundred novels, including the San-Antonio book series, dozens of plays and several screenplays, under his own name and a variety of pseudonyms. Dard used San-Antonio both as his most famous pen name and as the name of the titular hero of his main series. The San-Antonio books eventually became so popular that Dard started using that pen name also for books that did not belong to the series. Dard was best known for his raunchy humor and his inventive use of the French language, notably French slang. Source: Wikipedia (en)
