Sobibór extermination camp
When the war ended, she returned to Prague, where she learnt of her husband's death; her mother, who had been deported early in 1942, had died at Sobibór extermination camp. Helen began to correspond with Harry Lewis, a Czech with British nationality whom she had known at school and with whom she had had a brief romance before she met Hermann. She married Lewis in Prague in the summer of 1947 and in October moved to Belfast.
