Her suicide remained largely in the dark. Six days after her death, only the small local newspaper "Grunewald-Zeitung" reported that "the wife of Dr. H. in Dahlem, who is currently on the front, has set an end to her life by shooting herself. The reasons for this act of the unhappy woman are unknown." There is no evidence of an autopsy. The poorly documented circumstances of her death have resulted in considerable discussion and controversy as to her reasons, including that she opposed Haber's work in chemical warfare and her suicide was a response to him personally overseeing the first successful use of chlorine gas during the Second Battle of Ypres, resulting in over 67,000 casualties.
