Fritz Haber
Immerwahr's ashes were moved from Dahlem to Basel and buried together with Haber's after his death in 1934. Subsequently, their son Hermann Haber emigrated to the United States, where he eventually 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).
