German writer best known for his novel Der Streit um den Sergeanten Grischa (1927; The Case of Sergeant Grischa).

In 1933 Zweig left Germany for Czechoslovakia. He later lived as an émigré in Palestine until 1948, when he moved to East Germany. He served as president of the East German Academy of Arts from 1950 to 1953.

The Case of Sergeant Grischa depicts the social workings of the German army during World War I through the story of the Russian prisoner Grischa's tragic encounter with the vast machine of Prussian military bureaucracy. Zweig's other works include Junge Frau von 1914 (1931; Young Woman of 1914), De Vriendt kehrt Heim (1932; De Vriendt Goes Home), Erziehung vor Verdun (1935; Education Before Verdun), and Einsetzung eines Königs (1937; The Crowning of a King), each of which pursues the fortunes of characters introduced in The Case of Sergeant Grischa.
