O. W. Wilson

Wilson, together with his wife Ruth Elinor Wilson, had one daughter. Wilson had another son and daughter, by a previous marriage. After retiring from the Chicago Police Department in 1967, Wilson lived in Poway, California until his death in 1972.

In 1960, Chicago mayor Richard J. Daley, in the wake of a major police scandal, established a commission headed by Wilson to find a new police commissioner. In the end, Daley decided to appoint Wilson himself, as Commissioner. Beginning on March 2, 1960, Wilson served the Superintendent of Police of the Chicago Police Department until his retirement in 1967.

By the 1950s, Wilson's ideas of police professionalism, presented in Police Administration, were widely implemented in police agencies across the United States. These ideas remained popular until the advent of community policing. Wilson believed that preventive patrol and rapid response to calls would be effective, creating a sense of police omnipresence among criminals.

Wilson had also taught at Harvard University in the 1930s, working with the Harvard Bureau for Street Traffic Research. He also served as director of the New England Traffic Officers' Training School, which offered intensive two-week courses to police officers on traffic safety and enforcement. In 1939, Wilson became Professor of Police Administration at Berkeley. He served as the President of what would become the American Society of Criminology from 1942 through 1949. From 1950 to 1960, Wilson was the dean of Berkeley's School of Criminology. Wilson authored several books, including Police Records, Police Planning, and the highly influential work, Police Administration which was first published in 1943. While at Berkeley, Wilson also served as a consultant, advising cities including Dallas, Nashville, Birmingham, and Louisville, Kentucky on reorganization of their police agencies.

In 1925, Wilson became chief of police of the Fullerton Police Department for two years. He then spent two years as an investigator with the Pacific Finance Corporation. In 1928, at age 28, he became chief of police of the Wichita Police Department, where he served until 1939. In Wichita, he led reforms to reduce corruption. There he instituted professionalism in the department, requiring new hires to have a college education, and introduced innovations, such as the use police cars for patrol, mobile radios, and use of a mobile crime laboratory. He believed that use of two-way radio allowed for better supervision of patrol officers, and therefore more efficient policing. When the war ended, he remained in Europe until 1947, leading reorganization of police forces in Europe.
