Herman Goldstein is professor emeritus at the University of Wisconsin-Madison Law School and the original architect of the problem-oriented approach to policing. His first experiences in working with the police were in Philadelphia as a graduate student in governmental administration at the University of Pennsylvania and subsequently as an assistant to the city manager of Portland, Maine. He spent two years observing the on-the-street operations of the police in Wisconsin and Michigan as a researcher with the American Bar Foundations Survey of the Administration of Criminal Justice, and then participated in the analysis phase of that landmark project. From 1960 to 1964, he was executive assistant to the superintendent of the Chicago Police Department, O.W. Wilson, the widely recognized architect of the professional model of policing. Professor Goldstein has published widely on problem-oriented policing, the police function, police discretion, the political accountability of the police, and the control of police misconduct. He was co-author of the American Bar Association Standards Relating to the Urban Police Function. His 1977 book, Policing a Free Society, is among the most frequently cited works on the police. He first described the problem-oriented approach to policing in a 1979 article, which he expanded upon in his 1990 book, Problem-Oriented Policing. Professor Goldsteins research and writings have inspired many efforts to implement and advance problem-oriented policing in police agencies around the world.
