Clara Immerwahr - Death

Death

Shortly after his return, Immerwahr picked up Haber's military pistol and shot herself in the chest. She died in her son's arms. The morning after her death, Haber immediately left home to stage the first gas attack against the Russians on the Eastern Front. Her suicide remained largely in the dark; it was never in the newspapers and there is no evidence of an autopsy. The undocumented nature of her death has led to much controversy as to her motives.

Fritz Haber eventually fled the Nazis in Germany and died in Basel, Switzerland in 1934. His and Clara's ashes were buried together in a cemetery in Basel. Subsequently, their son Hermann Haber emigrated to the United States, where he committed suicide in 1946. Ludwig ("Lutz") Fritz Haber (1921–2004), the son of Fritz Haber and his second wife, Charlotte, published a book on the history of poison gas, The Poisonous Cloud (1986).
