Fritz Lickint Finds Evidence that Links Lung Cancer and Cigarettes

It is interesting to note, however, that in 1929 (presumably too late to be included in the handbook) the German physician, Fritz Lickint published a paper in which he showed that lung cancer patients were particularly likely to be smokers. He then went on a crusade against smoking, and antitobacco activism actually became widespread in Germany.
