Audrey Hepburn, who appears in several movies I've enjoyed, lived as a refugee in the Netherlands during WWII.
During the Dutch famine over the winter of 1944, the Germans confiscated the Dutch people’s limited food and fuel supply for themselves. Without heat in their homes or food to eat, people in the Netherlands starved and froze to death in the streets. Hepburn and many other Dutch people had to resort to using flour made from tulip bulbs to bake cakes and cookies.
This post has artwork of hers from that time.
