Dr. Weissmark is best known for her groundbreaking social experiment of bringing children of Holocaust survivors face-to-face with children of Nazis, and later, grandchildren and great-grandchildren of African American slaves with grandchildren and great-grandchildren of slave owners.

Her research provided a new framework for understanding the psychology of injustice, which has been applied to many conflicts stemming from centuries-old disputes, such as those in Israel, Northern Ireland, Bosnia, and Rwanda.

Dr. Weissmark's pioneering research was profiled on Dateline, CBS Morning News, WDR German TV, PBS, and in the New York Times, the Guardian, the Jerusalem Report, JUF News, Harvard Magazine, Jewish Federation News, Psychology Today, Frankfurter Allgemeine Zeitung, Harvard University Gazette, the Psychiatric Times, and the Chicago Sun Times.
