“Criminal Man,” originally conceptualized by Cesare Lombroso and expanded by Gina Lombroso, presents an in-depth classification of criminal types. Gina Lombroso’s analysis refines her father’s theories, categorizing criminals into atavistic, impulsive, and habitual offenders based on physical traits and social environment. By integrating psychological insights, she emphasizes rehabilitation over punishment, advocating training and support. This classification highlights the role of biological predisposition and environmental factors in criminal behavior, offering a nuanced framework for modern criminology. “Criminal Man” remains a pivotal reference for understanding the roots and remedies of crime.
