Karl Hass (5 October 1912 – 21 April 2004) was an SS Hauptsturmführer and German spy who helped deport more than 1,000 Italian Jews to Auschwitz. A perpetrator in the Ardeatine massacre, in which 335 civilians were murdered, he was tried and convicted in Italy in 1998. He spent the last years of his life under limited house arrest in "the splendor of the beautiful Swiss Alps".
