[The CROFF pavilion at the Policlinico Hospital in Milan: the beginnings].

This article collects the personal stories of the young doctors who in the early sixties contributed to the birth and development of the Croff pavilion at the Policlinico Hospital in Milan. Inaugurated on October 19, 1964, this has been the first institute in Italy entirely devoted to patients with kidney diseases. Since its inception, it has significantly contributed to the progress of nephrology thanks to important and pioneering investigations in the main fields of our specialty, which still continue nowadays. The different stories reported here follow the chronological order in which the young doctors arrived at Croff, each story representing a personal narrative that interweaves and integrates that of others. This gives rise to a vivid many-voiced account, from which emerge not only the figures of these young doctors, but also those of patients, nurses, and laboratory technicians.
