Cesare Lombroso was an Italian criminologist who argued that criminal behavior could be tied to inherited biological traits. In Criminology, he is known for early ideas about the “born criminal” and for shaping biological theories of crime.
Cesare Lombroso is the 19th-century criminologist most associated with biological explanations of crime. In Criminology, his name comes up when the course shifts from older ideas about crime as a rational choice to theories that look at the body, heredity, and physical traits.
Lombroso argued that some people are born with a criminal disposition. He thought crime was not just a matter of bad decisions or weak morals, but could be linked to inherited features that made certain people more likely to offend. That idea is called biological determinism, the belief that biology strongly shapes behavior.
His best-known work, L'uomo delinquente, or The Criminal Man, pushed the claim that criminals could be identified by physical characteristics such as skull shape, facial structure, or other bodily traits. He even suggested that some offenders were an evolutionary throwback, which is why his work is often connected to atavism. Today, those claims are rejected, but at the time they helped launch a more scientific, research-based approach to crime.
A lot of Lombroso’s conclusions came from studying incarcerated people and looking for patterns in their bodies. The problem is that prison samples do not represent all offenders, and physical appearance does not prove criminality. That is why his work is now taught as an early, flawed theory rather than a valid way to identify criminals.
Even with those flaws, Lombroso matters because he helped create the conversation around biological theories of crime. Later criminologists kept asking the same big question, just with better science: how much of criminal behavior is influenced by genes, brain chemistry, or other biological factors, and how much comes from environment and socialization?
Lombroso matters because he is one of the first names you need when tracing how Criminology became a distinct field. His work marks a shift away from purely moral or legal explanations of crime and toward theories that try to explain why certain people offend in terms of science.
He also gives you a starting point for biological theories of criminal behavior. Even though his specific ideas about skull shape and facial features were wrong, the larger question he raised did not disappear. Modern criminology still looks at biological influences, but it does so with genetics, neuroscience, and brain development instead of phrenology-style observation.
Lombroso is useful anytime a class asks you to compare old and new theories of crime. If you can explain why his approach was attractive in the 1800s and why it is considered unscientific now, you can handle discussion questions about determinism, bias, and the limits of early criminological research.

view galleryAtavism
Atavism is Lombroso’s idea that some criminals are evolutionary throwbacks, showing traits from earlier stages of human development. It is one of the clearest examples of how he tried to explain crime through biology instead of choice or environment. When you see atavism in a reading, think of it as the theory behind the “born criminal” label.
Positivism
Positivism is the broader approach that says crime should be studied with observation, measurement, and scientific methods. Lombroso fits inside this tradition because he tried to classify offenders by physical traits and patterns. In a course discussion, positivism is the bigger framework and Lombroso is one of its earliest, most famous examples.
Phrenology
Phrenology and Lombroso’s work are often grouped together because both tried to connect body shape to behavior. Phrenology focused on bumps on the skull, while Lombroso looked at facial features, skull structure, and other traits. Both are now seen as pseudoscientific, but they are useful for showing how early criminologists tried to make crime measurable.
Raffaele Garofalo
Raffaele Garofalo was another early criminologist linked to the positivist school. He shared Lombroso’s interest in scientific explanations of crime, but he focused more on the social and moral danger posed by offenders. Pairing the two helps you see that biological criminology was never just one idea, it developed through several related thinkers.
A quiz or short essay might give you a quote, a prison study, or a historical theory question and ask you to identify Lombroso’s view of crime. You should connect him to biological determinism, the “born criminal” idea, and the attempt to read criminality from physical traits.
If a prompt asks how criminology developed, Lombroso is a good example of the field’s move toward scientific explanation, even though his methods were weak. In a compare-and-contrast question, you can set him against classical thinkers like Cesare Beccaria, who stressed choice and punishment, instead of biology.
When you analyze a case scenario, the key move is to spot whether the theory assumes crime comes from inherited traits rather than social conditions. If it does, Lombroso is usually the right reference point.
Cesare Lombroso is best known for arguing that some people are born with criminal tendencies.
His work is tied to biological determinism, the idea that biology strongly shapes behavior.
He tried to identify criminals through physical traits, which is why his theory is now considered outdated and unscientific.
Lombroso still matters because he helped launch biological criminology and the scientific study of crime.
If a theory focuses on inherited traits or the “born criminal” idea, Lombroso is usually the historical reference.
Cesare Lombroso was an early criminologist who argued that criminal behavior could be explained by biology. He claimed some people are born criminal and tried to connect offending with physical traits like skull shape and facial features.
Lombroso believed crime could come from inherited biological traits rather than just choice or environment. He thought some offenders had characteristics that marked them as different from non-offenders, which is why his theory is linked to biological determinism.
Not in the way he proposed it. Criminologists reject the idea that you can identify criminals by looking at their bodies, but they still study biological influences such as genetics, brain structure, and neurochemistry.
Beccaria focused on rational choice, deterrence, and punishment, while Lombroso focused on biology and inherited traits. Beccaria explains crime as a decision, and Lombroso explains it as something rooted in the offender’s body or nature.
