Walther Stutzman was the husband of Esther Stutzman, and the father of Anna and Gottlieb. He and the rest of he family were secretly Jews living in Berlin. He and his family were present when their friends, the Gimpels, also Jews, informed their eldest daughter Alicia of her true heritage. More mundanely, Stutzman's suggestion of stealing Japanese computer technology to enhance Germany's computer capability was approved of by his boss, Gustav Priepke. This, despite the German assertion that the Japanese, as non-Aryans, were incapable of true innovation.
