About

Walter Gerhard Martin Sommer was an SS Hauptscharführer who served as a guard at the concentration camps of Dachau and Buchenwald. Sommer, known as the "Hangman of Buchenwald", was considered a depraved sadist who reportedly ordered two Austrian priests, Otto Neururer and Mathias Spannlang, to be crucified upside-down.
