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."
