Walter was born on February 27, 1926 to a family of wholesale paper merchants in Heilbronn, an industrial hub in southern Germany. When the antisemitism he experienced from his classmates and teacher became unbearable, 9-year-old Walter was sent to Luxembourg to live with relatives and attend school there. When the Nazi Aryanization laws came into effect in 1938, Walter’s father was forced to relinquish control of their business; on Kristallnacht, the family home was destroyed and his father was taken to Dachau, where he lost a finger to frostbite after being made to stand out in the rain all night. The Germans eventually released his father and both parents left the country to join Walter.
The remaining family got word that the Jews were relatively safe in the Italian-occupied part of France, so they made their way to Nice, where they were directed by the local Jewish community to a nearby village by the name of Saint-Martin-Vésubie, which became a safe haven for Jews1.
Walter joined the Underground in 1944. Because his spinal injury left him unable to walk without a cane, his primary responsibility was to solicit food from Italian farmers and manage paperwork. They lived up in the mountains in groups no larger than 20-25 people. The area was under partisan control: the local population was largely supportive, and the local authorities issued most of the partisans fake ID documents. To explain his thick accent, Walter's ID stated that he was born in France, near the German border.
One day, Walter was rounded up while attempting to buy food and taken to a jail in Cunio. After several days, as he was being taken to interrogation, a man walked up to him and offered to help him if Walter would act as an Italian interpreter for the German SS. Walter agreed, and to his surprise, the policemen that were escorting his group to interrogation simply let the strange man lead him away, out of their sight. As an Italian interpreter for the SS headquarters, he gathered critical intelligence, which he would relay every night to his liaison - a double agent working for the Underground. With the intelligence he learned, Walter even captured an Italian spy sent to locate Jews and partisans hiding in the mountainside. His unit actively engaged the Germans, once stalling a convoy of troops from advancing on a strategic road to France by employing mortar and small arms fire.
In 1997, Walter was invited by the Italian government to be honored for his role in the Underground. The woman who hid him in her parents' hotel — then in her 80s — was there in the crowd as he gave a speech, and when he mentioned her role in his story, she raised her hand and shouted, "I was that lady!" Walter eventually invited her to New York, where she spent a week with his family. This touching story made the front page of the New York Times.
Walter passed away on August 13, 2013. He is survived by his wife, three sons, and five grandsons.
Speaking about his odyssey through war-torn Europe, Walter would often tell his children, "the experience has helped me face life with a lot of courage, and surviving has given me a sense of pride."
