The Bow Street Runners were one of the first organized detective efforts in London, created by Henry Fielding, who served as a magistrate at Bow Street. He recruited and supervised a small group of men dedicated to investigating crimes, tracking down suspects, and bringing offenders to justice, laying the groundwork for modern detective work beyond simple patrols. That makes Henry Fielding the best answer. The other names refer to later policing developments: August Vollmer helped reform American policing in the early 20th century, Sir Robert Peel established the Metropolitan Police in 1829, and the London Metropolitan Police is the organization Peel created, not the founder of the Bow Street Runners.
