According to Konrad Kwiet, "After the war, the Australian Jewish community changed dramatically: It became a survivor community. Today, we have 100,000 Jews in Australia, and almost every second one must have some relationship to Holocaust survivors." A handful of the letters I found written to my grandfather are datelined Sydney. When I spoke to him on the phone before our meeting in Bad Arolsen, Kwiet explained further that he is interested in that migration to Australia—rather than to the United States or to Palestine. "Where Arolsen becomes important—almost as important as for academics—is for genealogical research. … They can now trace relatives … where they didn't know what happened to them. For individual genealogical research it is a gold mine."
