Simon Wiesenthal - Survivor, scholar, and Nazi hunter - has died in Vienna at 96.
"Survival is a privilege which entails obligations. I am forever asking myself what I can do for those who have not survived."
"Hatred can be nurtured anywhere, idealism can be perverted into sadism anywhere. If hatred and sadism combine with modern technology the inferno could erupt anew anywhere."
"If you know from history the danger, then part of the danger is over because it may not take you by surprise as it did your ancestors."
"There is no denying that Hitler and Stalin are alive today... they are waiting for us to forget, because this is what makes possible the resurrection of these two monsters."
Never, ever, ever forget.
