"In January 2007, the United States Holocaust Memorial Museum Archives received a donation of a photograph album. The inscription "Auschwitz 21.6.1944" on its first page signaled the uniqueness of the album—there are very few wartime photographs of the Auschwitz concentration camp complex, which included Auschwitz-Birkenau, the largest Nazi killing center. Though his name does not appear anywhere in the album, the dates of the photographs and various decorations including adjutant cords on the uniform of the album's owner, indicate that the album almost certainly belonged to and was created by SS-Obersturmführer Karl Höcker, the adjutant to the commandant of Auschwitz, SS-Sturmbannführer Richard Baer. Höcker was stationed at Auschwitz from May 1944 until the evacuation of the camp in January 1945. The photographs depict Höcker with other SS officers in Auschwitz in the summer and fall of 1944 and provide us with a new understanding of their lives and activities in the camp."
