Theo Markus Verderber's mother, Gelle, was among the Jews of Polish nationality expelled from Germany in October 1938. Theo and his younger brother were born in Germany, but went with their mother to a refugee camp in the border town of Zbaszyn. Hungry and cold, the refugees were stranded on the border, unwelcome in either Germany or Poland.
Theo was ultimately chosen to join a Kindertransport to England, arriving there in February 1939. His mother, sister and youngest brother remained in Europe and were killed in Limanow, Poland (near Krakow), in 1942. His older brother, Israel Moses, survived and immigrated to Israel
