Muselmann (German plural Muselmänner) was a slang term used amongst Jewish prisoners of German Nazi concentration camps during the Holocaust (World War II) to refer to those suffering from a combination of starvation (known also as "hunger disease") and exhaustion, as well as those who were resigned to their impending death. The Muselmann prisoners exhibited severe emaciation and physical weakness, an apathetic listlessness regarding their own fate, and unresponsiveness to their surroundings owing to their barbaric treatment.
