Sitting under a quote from former President Ronald Reagan, Helen Tannenbaum, a Polish Holocaust survivor from Dallas, waits for a memorial service to begin Nov. 2 at the United States Holocaust Memorial Museum. The museum celebrated its 10th anniversary earlier this month by bringing together thousands of Holocaust survivors in what may be one of the last gatherings of its kind. The quote from Reagan, referring to people who died in the Holocaust, reads: “We who did not go their way owe them this: We must make sure that their deaths have posthumous meaning. We must make sure that from now until the end of days all humankind stares this evil in the face … and only then can we be sure that it will never arise again.”
