German playwright.
After fleeing Germany in 1934, his family settled in Sweden. Weiss painted and made avant-garde films in the 1950s, then turned to fiction and drama, establishing a reputation in Germany with his novel Exile (1962). He won international acclaim for his play The Persecution and Assassination of Jean-Paul Marat as Performed by the Inmates of the Asylum of Charenton Under the Direction of the Marquis de Sade (1964; usually referred to as Marat/Sade ), which addressed themes of individualism, revolution, and violence. Associated with the Theatre of Fact movement, he also wrote the documentary dramas The Investigation (1965), The Song of the Lusitanian Bogey (1967), and Discourse on Vietnam (1968).
