On 18 May 1945 the Swiss-born ethnographer Alfred Métraux (1902–1964) wrote the following letter to his wife, Rhoda, from Tübingen, Germany: My darling, This afternoon I have been deeply shaken by the sight of a group of Jewish girls who were coming back from one of the death factories — Auschwitz. How to describe them? Imagine corpses who had emerged from the grave. There was around these ambulating skeletons something out of this world. A woman whom I thought to be about 50 turned out to be 23. As she collapsed and was obviously dying, she was taken away in a hurry. I talked with the others. No sooner one of them began to mention the horrors of the camp, the others started to cry and the girl became hysterical.

The above is an excerpt of Edgardo C. Krebs': Popularizing Anthropology, Combating Racism: Alfred Métraux at The UNESCO Courier. In this video he describes the main themes of that article. The video was recorded on occasion of the 70th anniversary history conference, held at UNESCO on 28 October 2015 and organized by the UNESCO Archives.
