Cesare Lombroso (born Ezechia Marco Lombroso; 6 November 1835 – 19 October 1909) was an Italian criminologist, phrenologist, physician, and founder of the Italian School of Positivist Criminology. Lombroso rejected the established classical school, which held that crime was a characteristic trait of human nature. Instead, using concepts drawn from physiognomy, degeneration theory, psychiatry, and Social Darwinism, Lombroso's theory of anthropological criminology essentially stated that criminality was inherited, and that someone "born criminal" could be identified by physical (congenital) defects, which confirmed a criminal as savage or atavistic.
