George Prochnik in The New Yorker:
The Austrian émigré writer Stefan Zweig composed the first draft of his memoir, “The World of Yesterday,” in a feverish rapture during the summer of 1941, as headlines gave every indication that civilization was being swallowed in darkness. Zweig’s beloved France had fallen to the Nazis the previous year. The Blitz had reached a peak in May, with almost fifteen hundred Londoners dying in a single night. Operation Barbarossa, the colossal invasion of the Soviet Union by the Axis powers, in which nearly a million people would die, had launched in June. Hitler’s Einsatzgruppen, mobile killing squads, roared along just behind the Army, massacring Jews and other vilified groups—often with the help of local police and ordinary citizens.
