Mannheim, who was Jewish, had been a principal actress in the Berlin Theatre but had to leave Germany when the Nazis came to power. She worked with Goring in many stage productions from the 1930s onwards and in seven episodes of The Adventures of the Scarlet Pimpernel, one of which he wrote especially for her, as well as in several films. Mannheim died in 1976, and the next year Goring married television director/producer Prudence Fitzgerald (1930-2018), who had directed him in many episodes of The Expert.
