The Criminal Man According to the Classification of Cesare Lombroso. Professor Lombroso was able before his death to give his personal attention to the volume prepared by his daughter and collaborator, Gina Lombroso Ferrero (wife of the distinguished historian), in which is presented a summary of the conclusions reached in the great treatise by Lombroso on the causes of criminality and the treatment of criminals. The preparation of the introduction to this volume was the last literary work which the distinguished author found it possible to complete during his final illness. The first idea came to me in 1864, when, as an army doctor, I beguiled my ample leisure with a series of studies on the Italian soldier. From the very beginning I was struck by a characteristic that distinguished the honest soldier from his vicious comrade: the extent to which the latter was tattooed and the indecency of the designs that covered his body. This idea, however, bore no fruit.
