Finding the lost girls of the Holocaust has been Heather Dune's mission for the past thirty years. "It still shocks me that no one knows that girls were the first targets in the mass genocide that is the Holocaust. That I have met so many of them and had the honor to listen to their stories is an honor that I do not have words to describe. I just want their stories to be recognized and to give them their place in history."

History is written by the victors - most of whom were men. It is only in the past five years that these women are finally being given their due. Thanks to Macadam's work, which is rec­og­nized by Yad Vashem in the UK and Israel, the USC Shoah Foun­da­tion, the Nation­al Muse­um of Jew­ish His­to­ry in Bratisla­va, Slo­va­kia, and the Panstowe Muse­um of Auschwitz in Oswiec­im, Poland.

She has a rescue lamb, horse, Dalmatian and calico cat, though who rescued whom is up for debate.
