Helena Petrovna Blavatsky (née Hahn von Rottenstern; 12 August [O.S. 31 July] 1831 – 8 May 1891), often known as Madame Blavatsky, was a Russian mystic and author who co-founded the Theosophical Society in 1875. She gained an international following as the primary founder of Theosophy as a belief system. Born into an aristocratic family in Yekaterinoslav, then in the Russian Empire (now Dnipro in Ukraine), Blavatsky traveled widely around the empire as a child. Largely self-educated, she developed an interest in Western esotericism during her teenage years.
