Clara Helene Immerwahr (German pronunciation: [ˈklaːʁa heˈleːnə ˈʔɪmɐvaːɐ̯]; 21 June 1870 – 2 May 1915) was a German chemist. She was the first German woman to be awarded a doctorate in chemistry from the University of Breslau, and is credited with being a pacifist as well as a "heroine of the women's rights movement". From 1901 until her death from suicide in 1915, she was married to the eventual Nobel Prize-winning chemist Fritz Haber.
