Weiss, Peter (Ulrich) (1916–1982)

German-born Swedish dramatist, novelist, and film producer. His first play, Marat/Sade 1964, achieved international success. It was followed by Die Ermittlung/The Investigation 1965, based on the Auschwitz trials; Gesang vom Lusitanischen Popanz/Song of the Lusitanian Bogey 1967, about the Portuguese exploitation of Angola and Mozambique; and Viet-Nam Diskurs/Vietnam Discourse 1968, tracing the political history of Vietnam.
