Army interrogator at the Freising Prisoner of War facility, obtained carbon copies of the originals from\"one of his source\" shortly after the close of World War II. Hecksher made photographs of the carbons, and gave one set to Walter Jessel. Jessel donated his set to the United States Holocaust Memorial Museum Archives in Feb. 1993, together with some partial translations."@eng . .
