Wolters' longtime secretary, Marion Riesser, was half-Jewish, and Wolters protected her throughout the war. In late 1944, word reached them that those with Jewish ancestry who remained free would be called up and used for cannon fodder. Wolters met with Riesser and the three other half-Jews in the Speer organizations, telling them if it became necessary (which it did not), the four would be transferred to essential war factories where they would be safe. Wolters told them, "With Albert Speer's help one can do anything."
