On wintry nights in a German concentration camp, a hungry teenager named Jack Sittsamer left his hard, wooden bunk, crept into the dark and risked his life just to steal a few potatoes from a warehouse in the compound.

Back in bed, the native of Poland often dreamt of sitting at a table with an entire loaf of bread and eating as many pieces as he wished.

“Before you went to sleep, they gave you a slice of bread, and you were supposed to eat it the next morning. But you were so hungry, you ate it that night,” said Mr. Sittsamer. After a terrifying odyssey through six concentration camps, he weighed 72 pounds when he was liberated in 1945.
