At the 1941 World Championships in Cortina d'Ampezzo, Cranz won three additional titles and then retired. Taking place during World War II with only Germany-friendly athletes, the championship was not acknowledged by the International Ski Federation. After her active career, Cranz publicly donated her skis and equipment, meticulously exploited by the NS-propaganda, for the "Winterhilfswerk" to support the Nazi-German troops and aggression against the Soviet Union.
