In Omeljan Pritsak and the intellectual origins of the Ukrainian “Harvard Miracle” (HURI, 2026), Andrii Portnov offers the first English-language biography of the co-founder of the Harvard Ukrainian Research Institute and the first professor of Ukrainian history at Harvard. Yevhen Yashchuk writes that Portnov shows why Pritsak is a special case to consider for those who are interested in the intellectual history of the twentieth century in general and the history of diaspora and exile scholars in particular.
