In addition to defining the character of the Wisconsin Law School and the university as a whole, Frank Remington had a major influence nationally in the fields of criminal law, criminal procedure, and criminal justice administration. He had a distinctive ability to bridge the gap between academics and practitioners. In one of his early articles, he presented his vision of how lawyers, especially law teachers, could contribute to criminal law and its administration. He advocated law teachers becoming involved in the specification of criminal conduct by proposing law reform and drafting statutes (the legislative task), in the work of committees that recommend procedural rules (the court rulemaking process), and in helping criminal justice agencies articulate administrative policies (the agency policymaking role). He also emphasized the roles of law teachers in training law students for involvement in all stages of criminal justice administration, the continuing education of the bar (the educational role), and in directly representing individuals or agencies in the operations of the system (the advocate role). He lived out his own model for the role of the law teacher. Remington's pioneering contribution has been in creating the field of study called criminal justice administration. He identified the important administrative decisions made at the lowest levels in criminal justice agencies and exposed the pervasive role that discretion has in the criminal justice system. In addition to profiling his efforts in the field of criminal justice administration, this biography also has chapters on his contributions in the fields of policing, corrections, court procedures, preparation of students for a career in law, and legal assistance to institutionalized persons. The concluding chapter explains how he applied his expertise in criminal justice to the regulation of intercollegiate athletics, as he provided guidance for the NCAA Committee on Infractions. A biographical summary includes his positions, publications, service, and recognition and honors.
