The two scrapbooks were compiled by Sophie Newman, mother of the donor, during World War II. The seven photographs of a concentrations camp were taken by the late Col. Max J. Mackler of the Army Corp of Engineers at the time of liberation. The photographs were originally donated to the Holocaust Library of the Hillel School in Tampa, Florida. From correspondence in the donor file, there is evidence to show that the Hillel Library Staff was able to identify the photographs.The Hill Staff used Inside the Vicious Heart: Americans and the Liberation of Nazi Concentration Camps by Robert H. Abzug, 1985, p. 54 and p. 131 and World at War: the Holocaust, by R. Conrad Stein, p. 35 and p. 42, for references. After collection by the Hillel Library staff, the photographs and the Sophie Newman scrapbooks were forwarded to United States Holocaust Memorial Museum. Esther Weiss seems to have acquired the photographs from Col. Mackler and included that as a part of her donation.
