Ruth Sellers (nee Hirsch) was born in Karlsruhe in 1922 to a Jewish father and non-Jewish mother who converted on marrying. Her childhood before 1933 was happy before she suffered increasing pressure of antisemitism. She was sent to Britain on the Kindertransport in December 1938. Her parents and younger sister remained in Germany. Her father and sister were deported to Theresienstadt towards the end of the war and survived. Ruth went to Cambridge, met her husband there and settled with him and their three sons near Chelmsford.
