Who was a significant contributor during the Reform era of policing?

August Vollmer is recognized as a significant contributor during the Reform era of policing due to his pivotal role in professionalizing the police force in the early 20th century. He championed the use of scientific methods in policing and emphasized the importance of education and training for police officers. Vollmer was instrumental in promoting the idea that policing should be based on principles of accountability and a desire to serve the community, moving away from the political influences that had previously plagued law enforcement. His efforts, particularly in establishing police academies and advocating for the incorporation of social sciences into policing practices, helped shape modern law enforcement and laid the foundation for contemporary approaches to policing.

Other contributors mentioned, while influential in their own rights, did not have the same direct impact on policing practices during the Reform era. J. Edgar Hoover shaped the FBI's policies and practices, but his era of influence aligns more with the post-Reform period. The FBI, as an organization, began to grow significantly under Hoover, but it wasn't a singular contributor to the Reform era in the way that Vollmer was. The Wickersham Commission investigated police practices and highlighted many issues within the system, but it was the application of Vollmer's ideas that led to the implementation of solutions.
