Biography

Zeisberg was born Ingmar Muhes in Danzig (present-day Gdansk). At the outbreak of World War II, Ingmar, with her ailing, widowed mother in tow, made her way to Denmark where both languished for two years in an internment camp. At war's end, Ingmar returned to Berlin to study journalism. By 1950, her career plans now changed, she enrolled at the prestigious Max Reinhardt Academy of the Deutsches Theater to study drama. Her stage debut in a production of Goethe's Faust followed soon after. Upon graduation, Ingmar found work as a theater and film critic in Cologne and also authored several screenplays.

In 1954, Ingmar was hand-picked by the director Georg Wilhelm Pabst to appear in the marital drama Afraid to Love (1954). She then had a successful run, appearing in many entertainments of varied genres: Heimatfilms, musical comedies, costume dramas and post-war Trümmerfilms, in most of which she worked under high profile directors like Helmut Käutner, Géza von Cziffra, Victor Tourjansky and Arthur Maria Rabenalt. By the early 60s, Ingmar starred in a couple of commercially popular Edgar Wallace-based potboilers (The Strangler of Blackmoor Castle (1963), The Inn on Dartmoor (1964)) and crime thrillers (Meet Peter Voss (1959), Nebelmörder (1964)). After a three-year long hiatus, she then also conquered the TV market, her most memorable role being the mariticidal Diana Stewart in the miniseries Wie ein Blitz (1970), adapted from a work by British crime novelist Francis Durbridge. Ingmar rounded off her career with seven appearances in the hit TV police series Tatort (1970).

The actress was married five times. Her exes included the producer Klaus Stapenhorst and the director Wolfgang Staudte. She was predeceased by her fifth husband, the architect and town planner Albert Speer Jr., son of the infamous former German Reich Minister of Armaments and War Production.
