Marie Steiner-von Sivers (1867-1948) was born in Wlotzlawek, in Russian Poland and grew up in St. Petersburg. She trained as an actor, but left the stage when she met Theosophy through Edouard Schuré, whose works she translated. In 1900, she met Rudolf Steiner, whom she later married and worked alongside in the development of Anthroposophy. She died in Beatenberg, Switzerland.
