Lorenzo Martini (1785–1844): A versatile scientific personality and his contribution to the history of hygiene

Abstract

Lorenzo Martini (1785–1844) was a physician devoted to promoting hygiene and preventive health. He combined clinical practice with public engagement and relied on both documentary records and debates to shape his practical advice. After a brief biographical profile, we turn to a close reading of the hygiene section of his Manuals of Hygiene and Medical Police (1835) and we examine how that part seeks to disseminate concrete hygienic practices among the population. The study rests on the original 19th-century edition of the Manual as a primary source, with other primary documents in the Historical Archives of the University of Turin and the State Archives of Genoa, and it is supported by secondary sources that help reconstruct Martini's life and situate his ideas within the medical culture of his time. Martini presents prevention as the primary route to protect health, and he argues that the best way to avoid or at least reduce the risk of chronic diseases is to maintain a general state of balance across all aspects of life, including daily habits, environment, diet. Traces of miasmatic and humoral theories of Hippocratic and Galenic origin remain in Martini's thought, showing how emergent preventive ideas coexisted with older medical doctrines.
