Tatiana Kisseleff (1881–1970) was born in Warsaw, Poland, to Russian parents. She studied law in France and later moved to Moscow, where she met and married the painter Nikolai Kisseleff. The couple became interested in Theosophy, and in 1911 Tatiana met Rudolf Steiner and Marie von Sivers in Hanover, Germany. Although Tatiana's interests lay in social work, Steiner directed her toward the art of eurythmy and took her on as a personal student. She studied eurythmy in Berlin before being invited to Dornach in 1914 to teach eurythmy. She devoted the rest of her life to practicing and teaching eurythmy.
