Karl Killinger was a devout Jehovah's Witness who remained faithful to his beliefs despite massive persecution by the Nazi regime. After his arrest, he was deported to the Dachau concentration camp and later transferred to the especially brutal subcamp, Gusen. He died there under inhumane conditions—exhausted, malnourished, yet steadfast in his faith.

• His life and death stand as an example of the quiet resistance of religious minorities against the Nazi dictatorship.
