Ernestine Pisk-Mittler was the mother of the notorious leader of the Jewish Security Forces in Camp Westerbork, Arthur Pisk (1891-1963), the "most hated man in Westerbork". Arthur Pisk was, through his collaboration with the SS in Westerbork, able to save the lives of his wife and son and escape to Australia after the war, but apparently was unable to save his own mother from deportation. It is also possible that the Nazis used Arthur Pisk's mother as a hostage in for blackmail purposes against him. (Stadsarchief Amsterdam Cards, Australian Death Notices)
