Fritz Lickint Finds Evidence that Links Lung Cancer and Cigarettes

Fritz Lickint of Dresden published the first good statistical evidence of a lung cancer tobacco link in 1929, based on a case series showing that lung cancer sufferers were likely to be smokers. Lickint also argued that tobacco use was the best way to explain the fact that lung cancer struck men four or five times more often than women (since women smoked much less) and that in countries where women also smoked, the sex difference was much smaller.
