About the author
Born in Dumbarton in 1745, Patrick Colquhoun built his early career in trade before moving into public life. He became a leading civic figure in Glasgow and later worked in London as a magistrate, combining practical experience in commerce with a strong interest in social policy and administration.
Colquhoun is most often remembered as a pioneer of preventive policing. He helped establish the Thames River Police, widely described as the first regular preventive police force in England, and argued that crime could be reduced through organized, professional systems rather than relying only on punishment after the fact.
He also wrote extensively on policing, political economy, and statistics. His books and public work made him an important voice in debates about urban government, trade, poverty, and security at the turn of the nineteenth century, and his ideas left a lasting mark on the development of modern public administration.
