Giulio Leonardo Cantoni (29 September 1915 – 25 July 2005) was the director of the United States' National Institutes of Health's Laboratory of Cellular Pharmacology, later renamed the Laboratory of General and Comparative Biochemistry.
Shortly after the fascists abolished the parliament, and introduced anti-Semitic laws, Cantoni, who was Jewish, fled with his family first to England.
As Cantoni was boarding a ship heading for the America, World War II broke out, and as an Italian citizen he was interned in England and later in Canada.
Cantoni got a job at University of Michigan's medical school, where he worked until he became an assistant professor of pharmacology at Long Island College of Medicine in 1945.
Before Cantoni died, he had four grand children, Ariella, Brendan, Ethan and Elliot.
