In November 1931, at the age of nineteen, he married twenty-nine year old Mary Westwood Steel at Gretna Green, Scotland (they had a second marriage ceremony in a London registry office in February 1932) and their only child, a daughter Phyllida, was born in March 1932. The marriage did not succeed and he became engaged in 1935 to ballet choreographer and designer, Susan 'Susy' Salaman, older sister of Merula Salaman Guinness, wife of Alec Guinness. Tragically, Susy contracted acute encephalitis in late 1935 and was left brain damaged. Marius wanted to go ahead with the wedding but Susy's father, Michel Salaman, would not allow it.
Marius first met Lucie Mannheim in late 1936.
After the success of "Nina" Lucie Mannheim was looking for a partner for her next play, "The Unknown Girl" by Franz Molnar, and decided on a certain Marius Goring, whose photo in the theatre almanac "Spotlight" she thought quite passable. Lehnhardt, Rolf. Die Lucie-Mannheim-Story. [The Lucie Mannheim Story] (Remagen-Rolandseck, Verlag Rommerskirchen + Co., October 1973), 47.
In June 1941, he and Lucie, who was thirteen years his senior, were married. Lucie had been a principal actress in the Berlin Theatre but had to leave Germany when the Nazis came to power as she was Jewish. She worked with him 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.
“The question must arise whether this was, like some other marriages at this time, a marriage of convenience, intended to give Mannheim British nationality, but it seems unlikely that was the main purpose. Goring had divorced his first wife in order to marry Mannheim and might well have married her earlier, if he had not been obliged to wait for his divorce to come through. It was not a short-lived marriage, lasting thirty-five years and ending only with Mannheim’s death in 1976, only after that did Goring marry for a third time.” 1.
After their marriage, Marius and Lucie were living at Cobham in Surrey, 20 miles south west of London but it was only 5 miles from the Vickers Aircraft Factory at Brooklands. The Luftwaffe successfully bombed the Vickers Factory buildings and extensively damaged the facilities on 4 September 1940. Nearly 90 aircraft workers were killed with at least 419 injured.
"Before the elementary horror of the war, which fell on London with the bombing raids and later with the bombardment with the V1 and V 2 rockets, Lucie Mannheim crept home like a terrified animal. She was simply unable to concentrate on any work; she admired her husband and his colleagues, who were meanwhile calmly playing Shakespeare's "Tempest" in London's Old Vic, like heroes. Later, on top of her own creature fear of the threat from the air, came the tormenting thought that people were in the old homeland and that her Berlin friends and relatives were no better off. With the move to a "quiet" country house twenty kilometres from the city, she went from bad to worse, because the Vickers aircraft works were nearby, a first rank magnet for German bombers, which in turn attracted the British interceptors. Only when their little house had a solid basement did Lucie's nerves solidify back to the point where she was capable of occupational therapy." Lehnhardt, Rolf. Die Lucie-Mannheim-Story.
