is the first comprehensive biography of Dawidowicz (1915–1990), a pioneer historian in the field that is now called Holocaust studies. Dawidowicz was a household name in the postwar years, not only because of her scholarship but also due to her political views. Dawidowicz, like many other New York intellectuals, was a youthful communist, became an FDR democrat midcentury, and later championed neoconservatism. Nancy Sinkoff argues that Dawidowicz’s rightward shift emerged out of living in prewar Poland, watching the Holocaust unfold from New York City, and working with displaced persons in postwar Germany. Based on over forty-five archival collections, chronicles Dawidowicz’s life as a window into the major events and issues of twentieth-century Jewish life.
