Biografia
Zeisberg was born Ingmar Muhes in Danzig (now Gdansk). At the start of World War II, Ingmar, accompanied by her ill, widowed mother, fled to Denmark, where they spent two years in an internment camp. After the war, she returned to Berlin to study journalism. By 1950, having changed her career path, she enrolled at the renowned Max Reinhardt Academy of the Deutsches Theater to study drama. Shortly after, she made her stage debut in a production of Goethe's Faust. Following graduation, Ingmar worked as a theater and film critic in Cologne and also wrote several screenplays.
In 1954, director Georg Wilhelm Pabst personally selected Ingmar to star in the marital drama Afraid to Love (1954). She then enjoyed a successful career, appearing in a variety of genres including Heimatfilms, musical comedies, costume dramas, and post-war Trümmerfilms, often collaborating with prominent directors such as Helmut Käutner, Géza von Cziffra, Victor Tourjansky, and Arthur Maria Rabenalt. By the early 1960s, Ingmar starred in several commercially successful Edgar Wallace adaptations (The Strangler of Blackmoor Castle (1963), The Inn on Dartmoor (1964)) and crime thrillers (Meet Peter Voss (1959), Nebelmörder (1964)). After a three-year break, she transitioned to television, delivering a memorable performance as the mariticidal Diana Stewart in the miniseries Wie ein Blitz (1970), based on a novel by British crime writer Francis Durbridge. Ingmar concluded her career with seven appearances in the popular TV police series Tatort (1970).
The actress was married five times. Among her former husbands were producer Klaus Stapenhorst and director Wolfgang Staudte. She was predeceased by her fifth husband, architect and town planner Albert Speer Jr., son of the notorious former German Reich Minister of Armaments and War Production.
