Paolo Tolentino (1914-1983), in 1960, became chief of the infectious diseases’ clinic at the Istituto Gaslini where he was put in charge of the whole patients testing process. Moreover, he gave the start to a new branch of public health since in 1957 he published a work on hospital infections, more specifically on hepatitis, for which he designed an innovative immunologic approach that eventually brought him to a very important recognition. Franco Soave (1917-1984) in the latest 50s was nominated Head of Pediatric Surgery at the Istituto Gaslini. In addition, in 1960 he elaborated a surgical technique on the congenital megacolon which is used as a treatment for Hirschsprung disease. Starting from 1970 Soave has also been the president of several societies, among which the Italian Society of Pediatrics and the American Pediatric Surgical Association. Silvano Mastragostino (1924-1998) in 1957 he became director of the child subdivision of orthopedics at the Istituto Gaslini. In 1954, he started studying orthopedic pathologies during evolutionary age, particularly the correction of the length differences of appendages, which lead him to perform the first tibial elongation in Italy. Moreover, in 1984 Mastragostino organized a voluntary work to help kids with locomotor difficulties in Kenya and in Benin. Such dedication brought him to receive a lot of awards, among which the famous Paul Harris Fellow.
