Anatomy
Andreas Vesalius (1514–1564) (Latinized from Andries van Wezel), professor of anatomy at the University of Padua, is considered the founder of modern human anatomy. Originally from Brabant, Vesalius published the influential book "De humani corporis fabrica" ("the structure of the human body"), a large format book in seven volumes, in 1543. The accurate and intricately detailed illustrations, often in allegorical poses against Italianate landscapes, are thought to have been made by the artist Jan van Calcar, a pupil of Titian.
Francesco Rizzoli
Francesco Rizzoli (11 July 1809 - 24 May 1880) was an Italian politician, surgeon and physician, considered one of the fathers of modern orthopedics.
Doctor Joseph Ruggi speaks of him in his 1924 memoirs: "During the intervention he was in such a state that he was screaming like a madman, 
sustaining and railing against his assistants who were confused and upset [...] while the patient, who was awake, shouted from his lungs, unheeded, throwing insults at the surgeon and his assistants."
