A doll, a rosary and a key are the treasured effects of two survivors, that will help tell the harrowing story of two of the 20th century's worst genocides. The three objects, from the Holocaust and the Rwandan genocide, were handed over at the dedication ceremony of the Johannesburg Holocaust and Genocide Centre.In a year's time the plan is to have them displayed when the centre is opened to the public.Yesterday dignitaries, academics, and a few survivors of the two genocides gathered to mark the event and remember.One of the guest speakers.
