Eugène-François Vidocq (French: [øʒɛn fʁɑ̃swa vidɔk]; 24 July 1775 – 11 May 1857) was a French criminal turned criminalist, whose life story inspired several writers, including Victor Hugo, Edgar Allan Poe, and Honoré de Balzac. He was the founder and first director of France's first criminal investigative agency, the Sûreté Nationale, as well as the head of the first known private detective agency. Vidocq is considered to be the father of modern criminology and of the French national police force. He is also regarded as the first private detective.
