Nadezhda Yakovlevna Mandelstam (Russian: Наде́жда Я́ковлевна Мандельшта́м, née Khazina; 30 October [O.S. 18 October] 1899 – 29 December 1980) was a Russian writer and educator, and the wife of the poet Osip Mandelstam who died in 1938 in a transit camp to the gulag of Siberia. She wrote two memoirs about their lives together and the repressive Stalinist regime: Hope Against Hope (1970) and Hope Abandoned (1974), both first published in the West in English, translated by Max Hayward.
Of these books the critic Clive James wrote, "Hope Against Hope puts her at the centre of the liberal resistance under the Soviet Union. A masterpiece of prose as well as a model of biographical narrative and social analysis it is mainly the story of the terrible last years of persecution and torment before the poet [her husband Osip] was murdered. The sequel, Hope Abandoned, is about the author's personal fate, and is in some ways even more terrible, because, as the title implies, it is more about horror as a way of life than as an interruption to normal expectancy. [The two books] were key chapters in the new bible that the twentieth century had written for us."
Nadezhda Khazina was born in Saratov, southern Russia, the youngest of four children (she had an older sister and two older brothers) of a middle-class Jewish family. Her parents were Yakov Arkadyevich Khazin and Vera Yakovlevna Khazina, and the family was wealthy enough to travel. Her mother was among the first group of women in the Soviet Union to complete training as a medical doctor, and her father was an attorney. The family did not practice Judaism, and kept Russian Orthodox holidays. Later they converted to Christianity. The family moved to Kiev, Ukraine, for her father's work, and the greater cultural and educational opportunities of the larger city. There she attended school. After gymnasium (secondary school), Nadezhda studied art.
