Born Jean Margaret Lodge on 4 August 1927 in Hull, Yorkshire, she began her career on the stage at the Windsor Repertory Company. Her first two films arrived in 1949: Dick Barton Strikes Back and Dr. Morelle: The Case of the Missing Heiress.

Lodge's best-remembered role came as Guinevere, wife of King Arthur, in The Black Knight — a Technicolor adventure that also featured Peter Cushing alongside Hollywood star Alan Ladd. She co-starred with Kenneth More in the 1952 comedy Brandy for the Parson, and her film credits spanned White Corridors (1951), Final Appointment (1954), Accidental Death (1963), The Eyes of Annie Jones (1963), and Invasion (1966).

Off-screen, Lodge was the centre of a family deeply rooted in British and American television. Her husband, Alfred Shaughnessy, was a two-time Emmy-nominated screenwriter who developed and served as head writer and producer on Upstairs, Downstairs, the ITV drama series that ran from 1971 to 1975. The couple married in 1948 and remained together until Alfred's death in 2005.

Their two sons carried the family name further into the industry. Charles Shaughnessy is best known to American audiences as Maxwell Sheffield on the sitcom The Nanny and as Shane Donovan on the daytime drama Days of Our Lives. David Shaughnessy worked as a producer on The Young and the Restless and a director on The Bold and the Beautiful — both long-running American soap operas.

Lodge is also survived by granddaughters Jenny, Katie, Maddy, and Josie, and great-grandsons Julian and Noa. Her career, stretching from post-war British cinema through the golden age of ITV drama and into the American soaps her sons helped shape, placed her at the intersection of three distinct eras of screen entertainment.
