Jonathan Wild, also spelled Wilde (1682 or 1683 – 24 May 1725), was a London underworld figure notable for operating on both sides of the law, posing as a public-spirited crimefighter entitled the "Thief-Taker General".
Wild was exploiting a strong public demand for action during a major London crime wave in the absence of any effective police force.
As a powerful gang-leader himself, he became a master manipulator of legal systems, collecting the rewards offered for valuables which he had stolen himself, bribing prison-guards to release his colleagues, and blackmailing any who crossed him.
He was responsible for the arrest and execution of Jack Sheppard, a petty thief and burglar who had won the public's affection as a lovable rogue.
However, Wild's duplicity became known, and his men began to give evidence against him.
After a suicide attempt, he was hanged at Tyburn before a massive crowd.
He was featured in novels, poems, and plays, some of them noting parallels between Wild and the contemporaneous Prime Minister Walpole, known as "The Great Corrupter".
