The police officials, detectives, federal agency directors and criminal justice administrators this atlas documents for their operational role rather than a published theory or forensic technique, from Eugene Francois Vidocq's founding of the Surete and Allan Pinkerton's private detective agency through J. Edgar Hoover's FBI directorship, Kate Warne as the first woman detective, and the FBI Behavioral Science Unit profilers John E. Douglas and Robert Ressler. Belongs here: any person whose primary documented role is leading, founding, staffing or directing a law enforcement, investigative or criminal justice administrative body. Does not belong here: people whose primary documented contribution is a published theory, grouped under Criminological Theorists and Social Scientists, or a forensic laboratory technique, grouped under Forensic Science Pioneers, even where an official also holds a criminology credential (several FBI profilers here also published academic research; their placement reflects the operational role this atlas documents most). This grouping is a browsing convenience organized around each person's primary documented professional role and is not a ranking or a complete account of a career.
