All Criminologists and Reformers

Named individuals whose research, writing or practical reform shaped criminology or criminal justice: theorists who built the field's explanatory models, empirical researchers, and practitioners such as prison and police reformers whose changes to practice are independently notable. The subcategories below sort these individuals by the school or era of the discipline their work belongs to. It excludes the theory or school itself, catalogued under Criminology Theories and Schools even when it carries the individual's name, and the institutions such a person founded or led, catalogued under Criminal Justice Institutions; a criminologist's page links to both rather than absorbing their content.
