Quick Summary

Jean-Charles-Pierre Lenoir was a French police official who served as Lieutenant General of Police. He was commissioned by King Louis XVI to write an account of the French police system, particularly in Paris, for Empress Maria Theresa of Austria.1

Lenoir's writings highlighted the effectiveness of inspectors in public safety, noting that those responsible for public safety secured more arrests than other police divisions. He explained that these inspectors patrolled at night with irregular forces, relying on informers to locate targets. This reliance on covert informants became a characteristic of French policing. The French police system, with its roots in the monarchy, evolved over time, with significant reforms occurring after the revolution under figures like Joseph Fouché.12
