Arnould Bonneville de Marsangy, born in Mons in 1802 and died in 1894 to Paris was a French magistrate.
He was a forerunner in the field of Criminology and originator of ideas such as the criminal (proposed in 1848 and introduced in 1850), parole (which he termed "preparatory liberations"), the generalization of fines in lieu of imprisonment or compensation for victims of a miscarriage of justice, as well, as recidivism.
