Richter's aunt had been murdered by the Nazis in the name of euthanasia, a crime for which his father-in-law from his first marriage, a Nazi doctor named Heinrich Eufinger, had been partially responsible. Richter painted a portrait of his aunt in 1965, based on an old photo. It was called 'Tante Marianne' / 9Aunt Marianne).
