Dimensions in Testimony: Interactive Biography in Spanish Aliza Liberman’s upbringing in Panama is inextricably tied to the Holocaust: it’s where her Polish-Jewish grandfather, a survivor, immigrated to after World War II. This deep connection to the Holocaust is the main reason Liberman chose to support the Institute’s Dimensions in Testimony (DiT) program, which enables people to engage with a prerecorded video image of a genocide survivor by asking him or her questions and hearing the survivor’s answers in real time.
