Soviet Jews lived through a record number of traumatic events: the Great Terror, World War II, the Holocaust, the Famine of 1947, the Doctors' Plot, the antisemitic policies of the postwar period, and the collapse of the Soviet Union. But like millions of other Soviet citizens, they married, raised children, and built careers, pursuing life as best as they could in a profoundly hostile environment. One of the first scholars to record and analyze oral testimonies of Soviet Jews, Anna Shternshis unearths their everyday life and the difficult choices that they were forced to make as a repressed minority living in a totalitarian regime. Drawing on nearly 500 interviews with Soviet citizens who were adults by the 1940s, When Sonia Met Boris describes both indirect Soviet control mechanisms?such as housing policies and unwritten quotas in educational institutions?and personal strategies to overcome, ignore, or even take advantage of those limitations. The interviews reveal how ethnicity was rapidly transformed into a negative characteristic, almost a disability, for Soviet Jewry in the postwar period. Ultimately, Shternshis shows, after decades living in a repressive, nominally atheistic state, these Jews did manage to retain a complex sense of Jewish identity, but one that fully disassociates Jewishness from Judaism and instead associates it with secular society, prioritizing chess over Talmud, classical music over Hasidic tunes. Gracefully weaving together poignant stories, intimate reflections, and witty anecdotes, When Sonia Met Boris traces the unusual contours of contemporary Russian Jewish identity back to its roots.
