" As historian A. Roger Ekirch explains in his 2005 book, At Day’s Close, the idea of lighting the streets of Paris back in the 1600s originally came from the police. Streetlights were one of many new patrol tools implemented by Louis XIV’s lieutenant general of police, Gabriel Nicolas de la Reynie. De la Reynie’s plan ordered that lanterns be hung over the streets every sixty feet—with the unintended side effect that Paris soon gained its popular moniker, the City of Light. The world’s most romantic city takes its nickname from a police operation. "
