Anna Abrikosova
Anna Ivanovna Abrikosova (Russian: Анна Ивановна Абрикосова; 23 January 1882 – 23 July 1936), later known as "Mother Catherine of Siena" (Russian: Екатери́на Сие́нская, Ekaterína Siénskaya), was a Russian Greek Catholic religious sister and literary translator, who died after more than a decade of solitary confinement as a prisoner of conscience in Joseph Stalin's concentration camps. Born into a family that had risen within only a few generations from serfdom into Chekhovian members of the hereditary Russian nobility, Abrikosova grew up as a family friend of Lev Tolstoy, Peter Kropotkin, and many other important figures in Russian political and intellectual life during the Silver Age.
