Anyone interested in the life of a dwarf at Auschwitz should read Primo Levi's excellent memoir, whose title has been translated both as "Survival in Auschwitz" and "If this is a man". Levi himself was not a dwarf, but he encountered one in the year he spent in Auschwitz, and the entire book is very well written. http://appliedsciencefreelibraryguide.org/view.php?id=388132
