The Museum of the Department of Public Health and Infectious Diseases, Sapienza University of Rome.

This paper illustrates in detail the birth of the Museum of Public Health of the Sapienza University of Rome, which has been one of the most successful achievements of Prof Carmine Melino in the last few years of his academic career. Backed by a very thin group of enthousiastic coworkers and colleagues, he recuperated all the instruments which had been used by the research groups active since 1880 at the former Institute of Hygiene, to which he added samples of the different pieces of laboratory furniture, ancient reagents, etc. The goal was not to simply collect, restore and maintain the documents of the Institute's past, but to rebuild a vintage laboratory, as it was inhabited by the hygienists of the past and to describe the kinds of research being performed during a period more than a century long. Beginning from the days when Hygiene became a scientific discipline, he tried to demonstrate that only the transformation of Hygiene into an experimental discipline made it possible the numberless achievements, including the improvements of the environmental conditions, the reduction of infectious diseases and the successful fight against the chronic, degenerative diseases of the present times.
