Nobel Prize controversies necessarily sympathize felt that it was wrong to (deliberately) offend Germany. Hitler's decree prevented three Germans from accepting their prizes: Gerhard Domagk (1939 Nobel Prize in Physiology or Medicine), Richard Kuhn (1938 Nobel Prize in Chemistry), and Adolf Butenandt (1939 Nobel Prize in Chemistry).
