Research and studies on tobacco's effects on the population's health were more advanced in Germany than in any other nation by the time the Nazis came to power. The link between lung cancer and tobacco was first proved in Nazi Germany, contrary to the popular belief that American and British scientists first discovered it in the 1950s. The term "passive smoking" (""Passivrauchen"") was coined in Nazi Germany. Research projects funded by the Nazis revealed many disastrous effects of smoking on health. Nazi Germany supported epidemiological research on the harmful effects of tobacco use. Hitler personally gave financial support to the "Wissenschaftliches Institut zur Erforschung der Tabakgefahren" (Scientific Institute for the Study of Tobacco Hazards) at the University of Jena, headed by Karl Astel. Established in 1941, it was the most significant anti-tobacco institute in Nazi Germany.
