Some exceedingly rare photos of SS officers at the Auschwitz death camp enjoying some leisure time after a hard day of gassing Jews and other "undesirables" have surfaced after more than 60 years.

From the NYT.com story:

As Ms. Rebecca Erbelding (archives at the U.S. Holocaust Memorial Museum) and other archivists reviewed the album, they realized they had a scrapbook of sorts of the lives of Auschwitz’s senior SS officers that was maintained by Karl Höcker, the adjutant to the camp commandant. Rather than showing the men performing their death camp duties, the photos depicted, among other things, a horde of SS men singing cheerily to the accompaniment of an accordionist, Höcker lighting the camp’s Christmas tree, a cadre of young SS women frolicking and officers relaxing, some with tunics shed, for a smoking break.

In all there are 116 pictures, beginning with a photo from June 21, 1944, of Höcker and the commandant of the camp, Richard Baer, both in full SS regalia. The album also contains eight photos of Josef Mengele, the camp doctor notorious for participating in the selections of arriving prisoners and bizarre and cruel medical experiments. These are the first authenticated pictures of Mengele at Auschwitz, officials at the Holocaust museum said.

The photos provide a stunning counterpoint to what up until now has been the only major source of preliberation Auschwitz photos, the so-called Auschwitz Album, a compilation of pictures taken by SS photographers in the spring of 1944 and discovered by a survivor in another camp. Those photos depict the arrival at the camp of a transport of Hungarian Jews, who at the time made up the last remaining sizable Jewish community in Europe. The Auschwitz Album, owned by Yad Vashem, the Israeli Holocaust museum, depicts the railside selection process at Birkenau, the area where trains arrived at the camp, as SS men herded new prisoners into lines.

The comparisons between the albums are both poignant and obvious, as they juxtapose the comfortable daily lives of the guards with the horrific reality within the camp, where thousands were starving and 1.1 million died.

Arbeit macht frei.
