Pictures taken by the SS
Pictures taken by SS man Dietrich Kammann showing prisoners digging and building barracks and crematoria, and also showing the inside of the crematoria with the furnaces, were concealed in the same way.
The Poles Ludwik Lawin and Taduesz Kubik worked in the camp photography studio. They stole 52 of Kammann’s negatives, wrapped them carefully, and buried them near a construction office barracks. After the war, Lawin led investigators to the spot.
Two Poles employed in the identification service (Erkennungsdienst) office, Bronisław Jureczek and Wilhelm Brasse, saved nearly 39 thousand contact prints of prisoner mug shots from destruction at the time of evacuation.
