Yvonne Mitchell was born on July 7, 1915, in London and was first and foremost a stage actress who, after being educated at St Paul's Girls School in London and The London Theatre Studio, began her theatrical career in the late 1930s. By the time of her death, she had performed under the theatre lights for over four decades. Her output in films and TV paled in comparison, but the work she put out in those mediums were of unusually high quality with mature themes. The dark-haired actress made her starring film debut in The Queen of Spades (1949) and proceeded to become a moving, thoughtful, often anguished presence throughout the 1950s, winning the British Film Award for her touching, sterling performance as the biological mother of a foster child in The Divided Heart (1954). Her slovenly, cuckolded wife in Woman in a Dressing Gown (1957) won her the Berlin International Film Festival Award. Other important films included Escapade (1955), Sapphire (1959), The Trials of Oscar Wilde (1960) and Johnny Nobody (1961). On the sly, Yvonne was a novelist of both children and adult books and an award-winning playwright. She also penned an enormously successful biography entitled "Colette--A Taste for Life" based on the famed French writer. The wife of film and stage critic Derek Monsey, she wrote her biography in 1957. She died of cancer on March 24, 1979, in London.
