The remarkable diaries of Zinaida Poliakova, deftly edited by ChaeRan Freeze, open onto the world of the “Russian Rothschilds,” a world of high culture, vast privilege and the skillful, constant fashioning of a hybrid Jewish-Russian identity. A superb biographical essay extends Poliakova’s story to fin-de-siècle Paris; the whirlwind of the Holocaust; and the harsh realities, both personal and financial, of her postwar life in England. … An important contribution to modern Jewish history.
